Guwei Electronics' USG series RF signal generator has 5 models to choose from. The USG series is a lightweight and USB compatible RF signal generator, with an output frequency range from 35MHz to 4400MHz; The USG series only provides continuous wave (CW) signal output and has no signal modulation function. The USG series RF signal generator has a built-in electronic attenuator that can adjust the power range from -30dBm to 0dBm. The USG series offers several different operating modes such as single point continuous wave, frequency sweep, frequency hopping, and power sweep, with frequency band limitations. The signal generator of the USG series provides relatively low harmonic output performance.

The figure shows the test results of USG-LF44 with simultaneous power scanning and frequency scanning. The frequency range of this test result is from 35MHz to 4400MHz and the power range is from -30dBm to 0dBm. The yellow record line represents the test result of recording the peak value. The pink record line represents the test result of the output signal during scanning.
