System Description - Agilent Technologies 89410A Operator's Manual

Extending Analysis to 26.5 GHz with 20 MHz Information Bandwidth

System Description

The wideband vector signal analyzer system consists of two major
components: an 89410A two-channel vector signal analyzer and a 71910A
wideband receiver with a wideband IF and quadrature outputs.
Note
The 89441A consists of an 89410A (the IF section) and an 89431A (the RF section).
To use an 89441A with the 71910A, disconnect the RF section and connect the IF
section to the 71910A as described in this chapter.
The 89410A provides the user interface and display, and performs all of the
signal processing.
The 71910A is basically a microwave spectrum analyzer with additional
features to optimize it for and signal monitoring applications. In this
application, it converts the RF or microwave signal into a baseband signal
which can be further processed by the vector signal analyzer. As the front end
of the measurement system, it also provides the necessary gain or attenuation.
