The VSG25A from Triarchy Technologies is an USB vector signal generator that operates from 1 MHz to 6.2 GHz. It features a 12-bit I/Q baseband arbitrary waveform generator which can be clocked at virtually any frequency from 54 kHz to 180 MHz, and includes a 4096 times 16 bit pattern buffer for built-in or custom modulation. The VSG6G1 is very compact and easy to carry, thus is an ideal choice for field test appplications. It measures 100 x 25 x 25 mm and weighs under 90g.
