Calibrating Using Electronic Calibration (ECal)
NOTE The isolation averaging default is set to take 10 sweeps. This isolation
averaging value is less than the network analyzer default sweep averaging
value of 16.
4. Press .
5. Continue with step 2 of “Perform the Calibration.”
Perform the Calibration
1. Press .
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 so that A is selected.
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:
— performs a measurement calibration for reflection-only. Measures
of one-port devices or properly terminated two-port devices, at port 1 of an
S-parameter test set.
— performs a measurement calibration for reflection-only. Measures
of one-port devices or properly terminated two-port devices, at port 2 of an
S-parameter test set.
— performs a complete calibration for measurement of all four
S-parameters of a two-port device. This is the most accurate calibration for
measurements of two-port devices.
— performs an S11 and S21 enhanced response calibration
(forward direction). Enhanced response generates a 1-port cal for S11 and an
improved calibration over the response cal for S21.
— performs an S22 and S12 enhanced response calibration
(reverse 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:
— performs a reflection 1-port calibration.
