Test Set Cal and SelfCal
Test Set Cal: An Overview
CAUTION Although the Test Set Cal can calibrate out the effects of your external hardware, the
drift-removing features of the SelfCal cannot remove drift associated with any
external fixtures or cabling. See Figure 3-4.
Be sure that all external fixtures and cables are extremely stable. Agilent
recommends the use of semi-rigid cabling external to your multiport test set. Design
fixturing such that movement of all cables and connectors is minimized.
Determining the Type of Calibration Kit to Use
For the most accurate calibrations and measurements, you should select a calibration
kit to match each connector of your DUT. This will ensure that no adapters are
needed after a calibration has been performed. Procedures to select a calibration kit
is given below. For more information on calibration kits, refer to the
E5061A/E5062A User’s Guide.
Step 1. Press [Channel Next] or [Channel Prev] to select the channel for which you want
to select the calibration kit.
Step 2. Press [Cal].
Step 3. Press
Cal Kit.
Step 4. Select the calibration kit you use.
NOTE Alternatively, you can also use [Cal] - Test Set Cal - Calibration - Cal Kit to select a
mechanical calibration kit. Follow these steps.
Step 1. Press [Channel Next] or [Channel Prev] to select the channel for which you want
to select the calibration kit.
Step 2. Press [Cal].
Step 3. Press
Test Set Cal - Calibration - Cal Kit and select a calibration kit you want to use
from the softkey menu.
NOTE The calibration kit definitions for Port 1 are used for the test set ports with an odd
number, while the definitions for Port 2 are used for the ports with an even number.
