Description
This is a high-performance 15 MHz synthesized function generator with built-in arbitrary waveform capability. Some of its features include 10 standard waveforms, a built-in 12 bi-bit 40 MSa/s arbitrary waveform capability and instrument state storage. The instrument includes control via an IEEE-488 (HP-IB) bus.
Note: sixteen of these instruments were purchased courtesy of a grant from Nortel.
