Signal processing and analysis functions can be had for less than $1000 with the Model 625A SmartARB, a dc-to-20-MHz, fully synthesized arbitrary waveform generator. Modes include not only the standard sine, square, ramp, triangle and random waveforms, but also AM, FM, PM, SSB, FSK, BPSK signal modulation, DTMF generate, DTMF detect, voltage and power measurement, and data and word generation. Researchers can even collaborate over the Internet by downloading custom waveforms.
