Overview
About GDM-906x Series
The GDM-906x Series delivers 6.5-digit resolution with 0.0035% DCV accuracy across 12 measurement functions, providing laboratory-grade precision in a benchtop form factor. Dual VFD displays enable simultaneous monitoring of two measurements, improving workflow efficiency during multi-parameter testing.
| Measurement Function | Description |
|---|---|
| DCV | DC Voltage, 0.0035% accuracy |
| ACV | AC Voltage (True RMS) |
| DCI | DC Current |
| ACI | AC Current (True RMS) |
| 2-Wire Resistance | Standard ohms measurement |
| 4-Wire Resistance | Precision low-resistance measurement |
| Frequency | Signal frequency counting |
| Period | Signal period measurement |
| Diode | Forward voltage test |
| Continuity | Audible threshold-based test |
| Temperature | Thermocouple and RTD |
| Capacitance | Component capacitance measurement |
Math functions including dB, dBm, compare, percent deviation, and MX+B scaling allow real-time data transformation without post-processing. Built-in data logging and statistics (min/max/average/standard deviation) support detailed measurement analysis over extended test runs, making the GDM-906x well suited for drift monitoring and environmental stress screening.
Calibration laboratories, component inspection teams, and R&D engineers use the GDM-906x for incoming inspection, production-line calibration verification, and precision measurement tasks where accuracy and repeatability are paramount. USB, LAN, and GPIB remote control enables integration into automated test systems, supporting SCPI command-driven measurement sequences.

GW Instek Insights
Emulating Processor Power for Thermal Testing: Why Constant Power
A heat sink or a cold plate is qualified against a watt figure, not a volt figure. This application note explains why a thermal load is driven in constant-power mode, how the bench is built for air and for liquid cooling, and what to confirm before you buy.
CRPS and Rack Power Supply Testing: The Six Tests That Matter
A CRPS module has to hold up under an unbalanced grid, a 0 to 100 percent load step, a surge on the line and a redundancy handover. This application note sets out the six tests, and the one source capability that makes a long feeder reproducible on the bench.
GPU Power Board Testing: DC Input Verification Before Integration
A GPU power delivery board is cheap to reject on a bench and expensive to find in an assembled server. This application note covers the programmable DC input test that screens the board, and the same test applied to incoming server systems.
