Automated Calibration Software Engineer

@maxscender

I’ll build you a hands-off calibration system that eliminates manual steps and delivers a defensible pass/fail verdict. The core architecture will be a VISA-compliant instrument layer with a generic SCPI parser, so detection and communication are handled automatically for all six device types. I’ll wrap that in an editable routine framework in Keysight VEE, where procedures are data-driven rather than hard-coded, allowing you to tweak measurement points, limits, and settling times without touching source code. For power sensor and microwave calibration specifically, I’ll implement routines that follow manufacturer specifications, including proper zeroing, calibration factors, and uncertainty analysis, with Test Uncertainty Ratios computed and displayed so your results are traceable and defensible. The GUI will show live instrument status, progress through each step, and a final summary report, but the system is designed to run fully unattended once the equipment is connected. I’m prepared for the long-term relationship and will work across your required time zones to ensure the system is maintained, extended, and documented to your standard.

The core challenge is building a calibration framework that is repeatable, instrument-aware, and precise enough to trust in a real lab—not just sending SCPI commands from a GUI. I have 9+ years of software engineering experience building automation, hardware-facing integrations, data logging, and test-oriented workflows, and I’m comfortable working with structured procedures, instrument drivers, and reproducible execution. I would design the Windows application around a VISA/SCPI abstraction layer, automatic instrument discovery, editable calibration routines, measurement capture, tolerance evaluation, and clear pass/fail reporting. Each device family would have its own driver module while sharing a common execution engine, so procedures can be modified without rewriting the whole application. I’d also preserve raw measurements and metadata so results can be audited and rerun consistently. Which exact instrument models and manufacturers are in your current six-device setup, and do you already have the Keysight VEE calibration template available for review?

For this calibration system, I’d build the instrument layer around VISA/SCPI so the six device types share one reliable communication framework while each calibration routine remains independently editable. The application would detect connected GPIB/LAN/USB instruments, identify the required driver, load the correct Keysight VEE-style routine, execute each measurement step automatically, validate results against the specified limits and generate a clear pass/fail record. Measurement data, instrument state and errors would be logged throughout so a failed run can be diagnosed rather than simply returning a failure. I’d keep the routine framework configurable so new procedures or instrument models can be added without rewriting the core application, then deliver the Windows executable, commented source and concise operating guide.

Hi, The difficult part is not just controlling six SCPI/VISA instruments it’s making them produce the same repeatable, hands-off calibration result every time, especially for the microwave power-sensor routines. I’d build the Windows application around VISA drivers for GPIB, LAN, and USB, with automatic instrument detection, routine selection, measurement capture, logging, and pass/fail evaluation. I’d keep the calibration procedures editable so specification changes or new routines don’t require rebuilding the application, while following your existing Keysight VEE template and manufacturer procedures. Could you share the VEE template and one representative power-sensor routine, including the required instruments and measurement sequence? Looking forward to hearing from you. Best Regards, Chand

@AneesaIBA

Hello, I have carefully read your project description and understand that you are looking for a skilled professional to develop a Windows-based automated calibration application for six laboratory instrument types, using SCPI/VISA control and Keysight VEE as the primary development environment. To approach your project I will first study your existing calibration template, instrument specifications, measurement sequences, and manufacturer procedures before building the driver and routine architecture. I will develop VISA-compliant instrument drivers for spectrum analyzers, power sensors, power loads, signal generators, VNAs, and directional couplers, supporting GPIB, LAN, and USB connections. The application will detect connected instruments, load the appropriate routine, execute measurements automatically, capture and validate results, log the data, and produce a clear pass/fail outcome. In terms of relevant experience, I have strong experience in automation, instrument control, SCPI/VISA integration, data acquisition, software development, and engineering workflows. I understand the importance of reliable communication, detailed logging, error handling, and repeatable measurement results in laboratory environments. I’d welcome the opportunity to review your existing VEE template and one representative calibration procedure so I can demonstrate how I would structure the driver and automation framework. Best Regards, Rabia Shaikh

@amadorjay

Hi there, The hard part is not just automating the calibration routines; it’s ensuring that each instrument functions flawlessly without manual intervention. For your project, a solid understanding of SCPI commands and the specific requirements of each device will be crucial. I can develop a Windows application that utilizes a user-friendly GUI and integrates with the required instrument drivers, ensuring compliance with VISA protocols. To clarify, how flexible is the routine framework you need? This will help me determine the best approach for your editable procedures. Looking forward to discussing the details in chat.

@mikes126

Hi there, let's have short meeting if you wanna discuss the calibration flow and your current Keysight VEE template. I can build the Windows automation around SCPI/VISA instruments, including spectrum analyzers, power sensors/loads, signal generators, VNAs and directional couplers. I’m comfortable with GPIB/LAN/USB communication, instrument drivers, automated test sequences, data logging and pass/fail logic. I’ll structure the driver layer and routine framework so you can easily add or modify calibration procedures later. I’ll also keep the source code clean and commented, with a simple GUI and user guide. The microwave/RF calibration side, power measurements, manufacturer procedures and uncertainty/TUR requirements can be handled carefully as part of the workflow. I’m also open to a long-term relationship and overlap with EST/CST/MST/PST hours.

@HamparProd

Hi, I can support the development and long-term maintenance of your automated calibration environment, working within the existing Keysight VEE architecture rather than attempting to replace an established laboratory workflow. I’m comfortable with SCPI/VISA-based instrument automation over GPIB, LAN and USB, including instrument discovery, command sequencing, measurement acquisition, limit evaluation, repeatable pass/fail logic, data logging and reusable calibration routines. I can work from your existing VEE template and manufacturer procedures to develop and validate routines for spectrum analyzers, signal generators, VNAs, power sensors/loads and directional-coupler workflows. I understand that repeatability, traceability and measurement uncertainty are more important here than simply getting an instrument to respond to commands. I’m also available for a long-term engagement during U.S. working hours.

Most instruments in that list speak SCPI over VISA, which makes the control layer tractable: a driver per instrument behind one common interface, so a routine reads the same whichever box it drives. The part that matters for calibration specifically is the record. Every run stores the instrument, serial number, firmware, the reference used, ambient conditions if you capture them, raw readings and the pass or fail against your tolerances. Certificates print from that record, so the paperwork always matches what actually happened. Two honest limits. I write the software; I am not a metrologist, so the procedures and tolerances have to come from you or your standard. And I cannot test against instruments I do not have, so I will need either remote access to a bench or a simulator plus your sign-off on real-hardware acceptance. Tell me the six models and their interfaces, GPIB, USB or LAN, and I will tell you which are quick and which will fight us.

@husainahmed2000

Hi There!!! You are looking for a software engineer to build an automated calibration application in Keysight VEE for testing six laboratory instruments using SCPI over VISA. WE HAVE ALREADY WORKED ON SIMILAR TYPE OF PROJECTS BEFORE Services provided for your project: * Custom automated laboratory equipment calibration routines development in Keysight VEE * VISA compliant instrument driver integration for SCPI command communication * Automated data logging framework for storing pass fail results in required formats * Microwave power sensor calibration procedure design per manufacturer specifications * Test Uncertainty Ratio calculations and editable procedure template setup Please join me in chat so we can discuss the specific instrument models you are testing. Best Regards, Hussain Ahmed

@thomasb726

Hello, The biggest risk is instrument heterogeneity and timing: differences in command sets, trigger behavior, and measurement latency across spectrum analyzers, power sensors, power loads, signal generators, vector network analyzers, and directional couplers will cause nondeterministic runs unless the driver layer enforces strict VISA-compliant session handling, standardized trigger and timeout policies, and a deterministic routine executor that serializes hardware access when needed. I have delivered multiple measurement and calibration projects where I built instrument driver layers, automated hands-off procedures, and produced Windows executables with editable routine frameworks. Relevant work includes a payroll API integration and a mission-critical tax filing system where I authored testable driver-like modules and full end-to-end automation, and several lab automation tasks using VISA and instrument control concepts. My background as a Senior Software Engineer and CTO-level contributor means I write maintainable source code, clear user guides, and I manage long-term support across EST, CST, MST, and PST schedules. I will start by creating a VISA-compliant driver abstraction for all six device classes, implement a routine framework that loads editable procedures, and add a deterministic executor with pass/fail logic and configurable logging formats. The first deliverable will be a working prototype that detects connected instruments and runs one complete calibration hands-off. - Do you have preferred manufacturers and models for each of the six instrument classes so I can target driver implementations up front? - Which logging formats and data fields are mandatory for acceptance: CSV, XML, binary, timestamps, uncertainty fields, or other? A quick call works for me whenever you are ready. Thomas Beigbeder

I’ll also create an editable routine framework, reusable instrument drivers, reliable error handling, and well-commented source code with a concise user guide. Timeline: 3 weeks I’m free to start immediately and can work across EST, CST, MST and PST hours. I’ll follow your existing Keysight VEE templates and specifications carefully and would be glad to build a long-term working relationship. Thanks

@SkillCrafts

I understand you require a robust, hands-off automated calibration solution for six laboratory instruments, similar to the SCPI-driven automation I've developed for spectrum analyzers and signal generators in previous projects. My experience with VISA interfaces (GPIB, LAN, USB) and SCPI command sets ensures seamless instrument communication. My proposed approach involves developing a Python application leveraging the `pyvisa` library for instrument control. I will create modular scripts for each instrument type, defining calibration routines based on industry best practices and your specific procedures. Data acquisition and storage will be handled via structured logging and CSV/database export. A clear pass/fail logic will be implemented for each calibration sequence. How are your existing calibration procedures documented? Are there specific SCPI commands you've found particularly reliable or challenging? I'm eager to discuss how we can implement this efficient, automated workflow.

Hello, I am a Software Development Developer with over 10 years of experience in the Software Engineering field. I understand the need for a custom software solution that automates calibration routines for laboratory instruments like spectrum analyzers and power sensors. My goal is to create an application that executes these procedures hands-off, with no need for operator intervention. I will develop a Windows executable application featuring an intuitive GUI. The software will detect connected instruments and load the appropriate routines automatically. Additionally, I will ensure that the application accurately logs and saves data in the required formats. This will allow for easy re-running of routines and consistent results within specification limits. My team will focus on building a robust instrument driver layer compliant with VISA standards, ensuring seamless communication with the specified devices. We will also provide an editable routine framework so you have full control over the calibration processes. I am open to a long-term working relationship and can accommodate various time zones as required. Thank you for reading my proposal to the end, and I sincerely hope to work on this project with you. Best, Stanislav

@rajeshrolen

Hi, At first glance, this looks straightforward but there’s usually one part that causes issues later. I’ve handled similar work before and can help you avoid that. Regards, Rajesh

@christopherm0620

Hello, Primary risk is achieving truly hands-off end-to-end calibration when instruments vary in firmware, SCPI dialects, or transient USB/VISA connectivity. I will mitigate this by implementing a resilient VISA-compliant driver layer with automatic device discovery, timeout/backoff, and stateful retries so routines never stall waiting for intermittent responses. I have implemented automated test and calibration systems for RF and microwave labs using instrument control frameworks comparable to Keysight VEE and LabView. That work included automated sweeps for spectrum analyzers and vector network analyzers, scripted control of signal generators and power sensors, and calibrated power load characterization. I have designed editable routine frameworks and GUIs that log data in CSV and XML, and produced user guides and full source repositories for handoff. I have direct experience with microwave power sensor calibration workflows and with documenting Test Uncertainty Ratios for lab procedures. I will start by reverse-engineering the set of instrument SCPI/driver peculiarities you have and building a modular, VISA-compliant instrument layer in Keysight VEE. The GUI will be an executable Windows app that loads editable routines and runs them fully unattended while producing pass/fail decisions and consistent recorded outputs. - Which specific models and firmware revisions of the six instruments will be in the initial scope? - Do you have preferred output formats for data logging and archival retention requirements? A quick call works for me whenever you are ready. Christopher
