May 19, 2015 - Signal Hound Introduces VSG25A vector signal generator that operates from 100 MHz–2.5 GHz with digital test pattern generation. It is USB-powered, weighs just 130 grams, and fits into a shirt pocket.
The VSG25A features a frequency range of 100 MHz to 2.5 GHz, output amplitude from -40 dBm to +10 dBm, and 100 MHz of modulation bandwidth. The VSG25A covers most telecom frequencies and two major ISM bands (902 MHz-928 MHz and 2.4 GHz-2.5 GHz).
Covering FM broadcast bands, it can be used down to 80 MHz with reduced amplitude accuracy.
Digital modulation comes as part of the VSG25A. Specific protocols are not supported—however, the modulation behind those protocols is supported. These include BPSK, QPSK, DQPSK, OQPSK, π/4 DQPSK, 8PSK, 16PSK, 16QAM, 64QAM, and 256QAM. Symbol rates from 4 kHz to 45 MHz are supported. Price: $495.
