Calibrating for Increased Measurement Accuracy
Calibrating for Noninsertable Devices
6. Perform a full 2-port calibration between ports 1 and 2 using calibration standards
appropriate for the connector type at port 2 (the connector type for adapter A2). Save
the calibration by selecting . Name the file "PORT2."
NOTE In the following steps, calibration data is recalled, not instrument states.
7. Press .
8. Turn the knob to select the file that contains the port 1 calibration data (where adapter
A3 was on port 2).
9. Press .
10.Turn the knob to select the file that contains the port 1 calibration data (where adapter
A3 was on port 1).
11.Press .
12.Press . Enter the delay value of the adapter from step 2f. Select the
appropriate type: or .
13.Press to complete the technique for calculating the new
coeffiecients and overwrite the current active calibration set in use.
This process uses up an internal memory register. The calibration in this register is not
the calibration created by adapter removal, rather it is a "scratch" calibration. You may
wish to delete the register, or re-save the new calibration in this register (step 14).
14.Press and
. You can now remove the adapter from the test setup and insert the
DUT.
