Description :
GW Instek debuts the brand new USG-Series RF signal generator, which 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 operational modes 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.
