Overview
About USG-LF44
The USG-LF44 is a compact USB-powered RF signal generator covering 34.5 MHz to 4400 MHz with continuous wave output from -30 dBm to 0 dBm. Powered and controlled entirely through a PC USB interface, it eliminates the need for a standalone benchtop instrument when a simple, portable CW source is sufficient. Phase noise of -107 dBc/Hz at 100 kHz offset and 10 kHz frequency resolution provide clean, stable output across the full operating range.

| Control | External PC software via USB |
Four operating modes, fixed frequency, frequency sweep, frequency hopping, and power sweep, address a range of RF testing scenarios from single-tone receiver sensitivity checks to automated frequency-stepped measurements and power linearity characterization. The frequency hopping mode is particularly useful for simulating agile RF environments during receiver robustness testing.
The USG-LF44’s compact USB form factor makes it an ideal companion for field service, portable test setups, and lab environments where bench space is limited. It covers key wireless bands including cellular (LTE, 5G sub-6 GHz), Wi-Fi (2.4 GHz and 5 GHz), Bluetooth, GPS, and ISM bands in a single device.
GSAS Micro Systems offers the USG-LF44 across India with RF application guidance, cable and adapter recommendations, and technical support.

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.
