Network Analyzer Calibrations
dynamic range of the system. Isolation cal is of great benet
when measuring lters or attenuators . High dynamic range
helps assure that low-level signals are not masked by crosstalk
responses .
P ARAM 1 1-P ort The 1-P ort calibration measures three classes of standards to
measure directivity , source match, and tracking (frequency
magnitude and phase) errors . A 1-P ort calibration is only
available for P arameter 1. However , you can redene
P arameter 1 to ratio any two inputs you desire .
Calibration Overview
In a typical application:
Set up your system for the measurement you want to make .
Select the type of cal you want to perform, Response , Response & Isolation, or P ARAM 1
1-P ort.
Connect the rst calibration standard and press the softkey for that standard. Repeat this
step for each required standard.
Save the calibration in any of eight calibration set memories .
Make actual measurements
The following diagram shows a typical operating sequence used when the device under test is
measured using more than one set of stimulus conditions (frequency range , number of points ,
source power).
