Introduction Model 5251 is a single-channel PXI-based Arbitrary Waveform
Generator. It is a high performance waveform generator that
combines five powerful instruments in one small package: function
generator, waveform generator, pulse generator, modulation
generator and a counter/timer. Supplied free with the instrument is
ArbConnection software, which is used for controlling the 5251 and
for generating, editing and downloading waveforms from a remote
computer. The following highlights the 5251 and ArbConnection
features.
