Test & Measurement
Test, Measurement & Production Automation
From bench to factory floor, automated test stations, flash programming, power profiling, protocol analysis, and oscilloscope integration for India's production lines.
What We Measure
Test and Measurement Services in India
Six measurement disciplines backed by the instruments we supply. Every tool listed here is deployed in our own engineering lab and on customer production lines.
Automated Test Stations
GSAS designs and deploys production test stations that automate repetitive measurement, programming, and validation tasks on the factory floor. We integrate instruments via SCPI, VISA, and vendor APIs, build custom test sequencers, and deliver turnkey stations with operator interfaces, pass/fail logging, and traceability. From incoming inspection to final test, every station is designed for throughput and reliability.
- Custom test sequencer development
- SCPI/VISA instrument control and automation
- Operator UI with pass/fail and barcode logging
- Data logging, SPC, and traceability integration
- Fixture design consultation and DFT review
Flash Programming: SEGGER Flasher, ProMik, Xeltek
Production flash programming at scale requires speed, reliability, and traceability. GSAS deploys SEGGER Flasher (in-system J-Flash), ProMik MSP2300Net (multi-site gang programming), and Xeltek SuperPro (universal socket programmers) for high-volume manufacturing. We handle flash algorithm development, programming sequence optimisation, and integration with MES systems.
- SEGGER Flasher standalone and in-line programming
- ProMik MSP2300Net multi-site gang programming
- Xeltek SuperPro universal socket programming
- Custom flash algorithm development
- MES integration and serial number injection
Power Profiling and Energy Analysis
Battery life and energy efficiency are critical design constraints for IoT, wearable, and edge devices. GSAS uses the Joulescope JS220 for DC energy measurement with nanosecond resolution, and PicoScope oscilloscopes for correlating power events with firmware execution. We profile sleep/wake transitions, quantify peripheral current consumption, and optimise firmware for minimum energy per operation.
- Joulescope JS220 DC energy measurement and profiling
- Sleep/wake current profiling with nanosecond resolution
- Firmware energy optimisation and power mode tuning
- Battery life estimation and validation testing
- Power delivery network (PDN) analysis
Protocol Analysis: Total Phase Beagle and Promira
Debugging communication protocols requires visibility into what is actually on the wire. GSAS deploys Total Phase Beagle protocol analyzers for non-intrusive I2C, SPI, and USB monitoring, and the Promira Serial Platform for active protocol exercising and testing. We capture, decode, and diagnose protocol-level issues that oscilloscopes cannot resolve.
- Beagle I2C/SPI protocol analysis and capture
- Beagle USB 480/5000 for USB 2.0 and 3.0 analysis
- Promira platform for active I2C/SPI host/client testing
- Protocol conformance testing and timing validation
- Custom protocol decode and analysis scripting
Oscilloscope Integration: GW Instek and Pico Technology
Oscilloscopes remain the backbone of embedded hardware validation. GSAS integrates GW Instek benchtop oscilloscopes and Pico Technology USB-based PicoScopes into automated test workflows. We configure remote control via SCPI, build automated measurement scripts, and deploy oscilloscope-based test stations that capture waveforms, measure timing, and verify signal integrity without manual intervention.
- GW Instek DSO and MSO series deployment and SCPI control
- PicoScope USB oscilloscopes for portable and automated use
- Automated waveform capture and parametric measurement
- Signal integrity validation (rise/fall, overshoot, jitter)
- Integration with test sequencers and data logging
Production Test Workflows
A test station is only as good as the workflow around it. GSAS designs end-to-end production test workflows covering incoming component inspection, in-circuit test (ICT) integration, functional test, programming, calibration, and final acceptance. We document test procedures, train operators, and establish yield tracking and failure analysis processes.
- End-to-end production test workflow design
- Test procedure documentation and operator training
- Yield tracking, SPC, and failure analysis processes
- First Article Inspection (FAI) support
- Test coverage analysis and gap remediation

Test and Measurement Insights
100BASE-T1 Link Won't Come Up: A Vendor-Neutral Checklist
A 100BASE-T1 link that will not come up is almost never a mystery, but the answers on the web are written per silicon vendor and do not transfer. This is the ordered bring-up checklist that holds regardless of which PHY, switch or SoC you have: physical layer first, then the PHY over MDIO, then the master and slave pairing, then the causes of a link that comes up and drops. The standards and tooling claims trace to IEEE 802.3 task force records, the Linux ethtool and kernel documentation or published test material. Written by the GSAS Micro Systems engineering team in India.
100BASE-T1 Media Converters: How to Choose One
Search for a 100BASE-T1 media converter and you get SKU pages that document their own DIP switches, plus a pile of copper-to-fibre converters that have nothing to do with single-pair automotive Ethernet. This is the selection guide neither publishes: what the box does at the PHY layer, when a converter is the wrong box, and the nine criteria that decide fitness, each written as a question to put to the supplier rather than a specification we invented. Standards claims trace to IEEE 802.3 task force records and the public OPEN Alliance specifications. Written by the GSAS Micro Systems engineering team in India.
ADAS Sensor Data Logging: Bandwidth Budgets That Add Up
Every page that tells you an ADAS test vehicle produces terabytes a day states the headline and skips the arithmetic, so you cannot redo it for your own sensor set. This article publishes the arithmetic instead: one formula, every table row derived on the page, a worked eight-hour drive that chains those rows into a sustained write rate, a media count and an offload window, and the five places bandwidth budgets go wrong. Written by the GSAS Micro Systems engineering team in India.
Automotive Data Loggers: Capture Without Loss
Search for an automotive data logger and the results split into cheap OBD dongles at one end and enterprise ADAS recorders at the other, with nothing in between explaining the engineering that decides whether you lose frames. This is the loss budget end to end: mirror oversubscription upstream of the logger, encapsulation overhead on the capture path, sustained write rate against burst rate, rotation stalls, and storage arithmetic worked in full so you can redo it with your own numbers instead of trusting ours. Written by the GSAS Micro Systems engineering team in India.
Automotive Ethernet Conformance: TC8 and Testing Above It
Summarising TC8 as a layer 1 to layer 4 suite is wrong in both directions. The public OPEN Alliance ECU test documents run from transmitter distortion up to a SOME/IP chapter with its own standardised test stub, and they contain exactly one time synchronisation test case. This is what those documents enumerate, chapter by chapter, what genuinely lives above their boundary, why a passing ECU can still fail against a partner node, and how much pre-compliance work a Tier-1 in India can honestly do in-house before a test house visit. Written by the GSAS Micro Systems engineering team in India.
How to Choose an Automotive Ethernet Switch for the Lab
Search for an automotive Ethernet switch and you get silicon selection tables written for the engineer choosing a die for a zonal controller. The person searching from a validation lab wants a boxed switch that reproduces a vehicle network on a bench, and finds nothing addressed to them. This is that guide: how to separate the two products, how to count the ports you actually need, and an eight-row scoring matrix written as questions to put to a supplier rather than specifications we invented. Standards and documentation claims trace to IEEE 802.1 and 802.3, ASAM, AUTOSAR, the IETF and public Linux and Wireshark documentation. Written by the GSAS Micro Systems engineering team in India.
