Agilent E8257D is a fully synthesized signal generator with high output power, low phase noise, and modulation capability. Specifications apply over a 0 to 55 °C range unless otherwise stated, and apply after a 45-minute warm-up time. Supplemental characteristics denoted as typical, nominal, or measured, provide additional (non-warranted) information at 25 °C, which may be useful in the application of the product. Unless otherwise noted, this data sheet applies to units with serial numbers ending with 50420000 or greater.
Keysight (Agilent) E8257D is The Industry’s Best Performance up to 67 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 eliminate the need for 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
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.
