Perform The Calibration - Agilent Technologies 8753ET User Manual

Perform the Calibration

1. Press
Cal ECal MENU
When ECal is first selected (or when you select module A or module B), there is a small initial delay so
that the network analyzer can detect and download the calibration information from the internal memory
of the ECal module.
2. Press
MODULE A b
NOTE If you are calibrating with two modules, the overlapping frequency span will be determined
by the second module. Therefore, if you want to use the calibration data of Module A in the
overlapping frequency span, calibrate using Module B first, and then calibrate using Module
A.
3. Press the ECal calibration selection.
• The calibration choices for ES models are:
—
S11 1-PORT
devices or properly terminated two-port devices, at port 1 of an S-parameter test set.
—
S22 1-PORT
devices or properly terminated two-port devices, at port 2 of an S-parameter test set.
—
FULL 2-PORT
a two-port device. This is the most accurate calibration for measurements of two-port devices.

S11/S21 ENH. RESP.
direction). Enhanced response generates a 1-port cal for S11 and an improved calibration over the
response cal for S21.
—
S22/S12 ENH. RESP.
direction). Enhanced response generates a 1-port cal for S22 and an improved calibration over the
response cal for S12.
• The calibration choices for ET models are:
—
REFLECTION 1-PORT
—
TRANS/REFL ENH. RESP.
S11) enhanced response calibration (forward direction). Enhanced response generates a 1-port
cal for reflection and an improved calibration over the response cal for transmission.
Once the ECal calibration selection is made, the network analyzer performs the calibration.
4. If you selected the manual thru calibration option, when the prompt is displayed, remove the ECal
module from the setup and connect the manual thru (the two test ports connected together) as shown in
Figure 6-22.
