2 Theory of Operation

Overview

The 8990B is a peak power analyzer designed to provide accurate radar pulse
analysis measurement. A combination of the 8990B and the N1923/4A wideband
power sensor enables the RF pulse rise/fall time measurement of up to 5 ns.
The 8990B has a high sampling rate of 100 MSa/s for RF channels. This enables
the peak power analyzer to offer faster measurement speed and greater
measurement accuracy in key applications such as radar pulse analysis and
wireless pulse measurement.
The peak power analyzer is also able to perform auto-zeroing and calibration
function to eliminate the need to connect and disconnect from the calibration
source and reduces the test time and measurement uncertainty.
