Keysight / Agilent E8257D 007 1ED 520 PSG Microwave Analog Signal Generator, 250 kHz to 20 GHz

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 PSG analog signal generator's 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 (typically -126 dBc/Hz @ 10 GHz carrier and 10 kHz offset) 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 analog signal generator delivers the performance you demand. Modular Microwave Signal Generator Platform – Optionally Add AM, FM, ØM, and/or Pulse Modulation Generate continuous wave (CW) signals for LO substitution or swept stimulus response analysis. Optionally add AM, FM, ØM and/or pulse modulation to accurately characterize RF and microwave components and devices. Many performance enhancement options are also available to configure the signal generator to meet your specific test requirements. Tailor the PSG for today's RF and microwave test applications and easily upgrade in the future as your needs change.
