Introduction

Overview of the 8990B

The 8990B is a peak power analyzer that consists of two RF input channels
(1 and 4) and two video input channels (2 and 3). When used with a compatible
wideband power sensor, the 8990B is able to measure the dynamic or
time-dependent aspects of RF and microwave power. 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 video inputs of the 8990B allow the simultaneous
analysis of time-domain control signals.
The 8990B has a frequency range of 50 MHz to 40 GHz and a dynamic power
range of –35 dBm to 20 dBm, depending on the wideband power sensor used.
The 8990B is capable of measuring peak power, minimum power, average power,
peak-to-average power, pulse repetition interval, pulse repetition rate, rise time,
fall time, pulse off time, pulse top, pulse base, pulse width, duty cycle, and
overshoot. The 8990B also provides internal and external trigger functions.
