Wide-Band Noise Source (10 - 1600 MHz)
  • Frequency (10 - 1600 MHz)
  • ~15 dB ENR* (Calibrated ENR values measured at 72.3°F against calibrated Agilent 346B noise source)
  • Supply voltage (16 - 28 V)
  • Operating current ( < 10mA)
  • RF OUT ( N-Type Male)
  • Power Connector ( BNC Female)
  • Compatible with HP8970A/B and Ailtech/Eaton noise figure measuring instruments
  • Low cost add-on for spectrum analyzers without a tracking generator (May need additional high gain amplifiers)
  • One-year conditional warranty
  • Used by various universities, research and manufacturing facilities worldwide
  • Low cost alternative to traditional HP/Agilent noise sources for noise figure measurements

Please note picture is of a stock item for illustration only. You will receive a similar-looking  item but the frequency vs ENR values on the label may be different.

See our other listing if you require an SMA RF connector.

* Other lower value ENR tables also available by request.


FAQ: Why can’t I see my noise source on a spectrum analyzer?


"If you are attempting to measure a lower power noise source, < 30 dB ENR, in all probability the
spectrum analyzer Noise Figure, which usually is at a minimum of 25 dB and many times is 35
dB, is above the noise level of noise source. At these levels we can approximate Noise Figure
and ENR and compare directly to see if the noise source will be detectable. This source could be
measured with an LNA in front of the Spectrum Analyzer". - NoiseWave application note
