This unit includes options 520/UNX/1EA/1E1/1EH

The E8257D PSG analog signal generator delivers industry-leading output power, level accuracy, and phase noise performance up to 67 GHz (operational to 70 GHz). The E8257D PSG high output power and superior level accuracy often eliminates the need of an external amplifier for testing high power devices and minimizes test uncertainty to identify errors early in the design process. The world-class phase noise performance is ideal for local oscillator, low jitter clock substitution and adjacent channel selectivity tests. When testing advanced RF & microwave radar, communications, and control systems, the PSG delivers the performance you demand.
