Tektronix 492A-01

This is a Spectrum Analyzer with a frequency range of 50KHz to 21GHz.

It has calibrated amplitude and frequency coverage from 50KHz to 21GHz in coax, and to 325GHz using Tektronix WM490 Series high performance waveguide mixers.

Center frequency accuracy is excellent; typically 1KHz at 100MHz, 10KHz at 10GHz and 40KHz at 40GHz.

Negligible long term frequency drift ensures measurement repeatability.

It has 100Hz resolution bandwidth to 220GHz and 1KHz resolution to 325GHz with high sensitivity and low phase noise.
