Technology type: Signal Generators

GW Instek offers the brand new USG-Series RF signal generator, which comes with five models to meet users’ requirements and is a pocket-sized, USB interface compatible RF signal generator with the frequency range from 35 MHz to 4400 MHz. 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.

It has several operational modes including fixed frequency, frequency sweep, frequency hopping, and power sweep. The frequency bandwidth limitation of the USG-series provides lower harmonic output performance.
