Figure 3-37 Adapter removal and insertion function calibration interface
Adapter insertion operation Steps:
1. Remove any test cables from the ports of the analyzer and perform a full 2-port calibration.
2. Select
Cal
→
Adapter Removal
to go to the Settings screen and select
Insert
in the
Adapter
tab.
3. Connect the adapter on the test cable, select
Cal
→
Adapter Removal
→
Calibration
to
enter the
Adapter Removal
configuration screen. Select the port connected with the
adaptor to be inserted, select the calibration kit model, select the polarity of the calibration
kit, and click
Next
to connect the Open, Short, and Load calibration elements in turn for
full 1 port calibration.
4. Click
Finish
to complete the calibration and click
Adapter Removal
to ON to complete the
Adapter insertion operation.
“Adapter Rotate” is also known as the "equal exchange adapter and equal length adapter"
calibration method. Before the unknown pass-through method was introduced, the
switching adapter method was often used as a faster alternative to the more tedious
adapter removal method.

ECal Overview
ECal is a new automatic calibration technology for vector network analyzers. Every ECal
module contains electronic standards that are automatically switched into position during a
measurement calibration. These electronic standards have been measured at the factory and
the data stored within the memory of the ECal module. The analyzer uses this stored data,
along with the measured data, to calculate the error terms for a measurement calibration. ECal
offers the following advantages:
⚫
The calibration process is simple. The electronic calibrator only needs to be connected to
the VNA once to complete the test items required by the dual-port calibration, without the
need for multiple calibration connections.
⚫
A shorter time is required for calibration.
