Specifications

The MS462XX is a self-contained, fully integrated measurement
system that includes an optional time domain capability. The system
hardware consists of the following:
q
Analyzer
q
Precision components required for calibration and performance
verification
q
Optional use of Anritsu 67XXB, 68X/ 69X or MG369X series
synthesizers as additional sources
The MS462XX internal system modules perform the following
functions:
Source Module
or Modules
This module provides the stimulus to the device un
-
der test (DUT). The frequency range of the source
and test set modules establish the frequency range
of the system. The frequency stability of the source
is an important factor in the accuracy (especially
phase accuracy) of the network analyzer. Hence, the
MS462XX always phase locks the source to an inter
-
nal (or optional external) 10MHz crystal reference.
Test Set
Module
The test set module routes the stimulus signal to
the DUT and samples the reflected and transmitted
signals. The type of connector used is important, as
is the “Auto Reversing” feature (462XB only). Auto
Reversing means that it applies the stimulus signal
in both the forward and reverse direction. The direc
-
tion is reversed automatically. This saves you from
having to reverse the test device physically to mea
-
sure all four scattering parameters (S-parameters).
Frequency conversion occurs in the analyzer.
