GW Instek USG-Series RF signal generator comes with five models to meet users’ requirements and is a pocket-sized, and USB interface compatible RF signal generator with the frequency range from 35MHz to 4400MHz. The USG-Series provides continuous wave (CW) signal outputs without any signal modulation function. The built-in electronic attenuator of the USG-Series allows an adjustable power range from -30dBm to 0dBm. The USG-Series has several operationalmodes including fixed frequency, frequency sweep, frequency hopping, and power sweep. The USB-Series RF signal generator, with the frequency bandwidth limitation, provides lower harmonic output performance.

Figure shows the test result of USG-LF44 simultaneous power sweep and frequency sweep. The test result covers the frequency range from 35MHz to 4400MHz and the power range from -30dBm to 0dBm. The yellow trace illustrates the test result of maximum hold and the pink trace shows the test result of signal output.

GWINSTEK USG RF Portable Signal Generator Introduction

GWINSTEK USG RF Signal Generator PC Application Program Demo

Primary RF Software Demo ( USG RF Signal Generator & GSP-730 Spectrum Analyzer)

A USG CD-ROM provides dedicated PC application programs, which were developed under JAVA software* structure. Users must install JAVA software to use USG PC application programs, which support operating systems such as Windows 2000/XP/Vista/7/8, Linux & Mac OS X through the USB interface.

Users can download USG APP to smart phone or tablet with Android 4.0 or above. To operate USG, use USB-OTG connecting cable to connect tablet (or smart phone) and USG. The Android APP application software for the USG signal generator is available on Google Play Store.

The USG signal generator can be designated as the tracking generator for GSP-730 spectrum analyzer to conduct measurement functions of scalar network analyzer. A USG CD-ROM provides PC application programs for the Primary RF software. Users can, using a Windows OS computer, control USG and GSP-730 via the Primary RF software. The NI-488.2 software** must be installed first before installing Primary RF software
