In enhanced response calibration, calibration data are measured by connecting an OPEN standard, a SHORT standard, or a LOAD standard to the output port (or a THRU standard between two ports). This calibration effectively eliminates the directivity error, crosstalk, source match error, frequency response reflection tracking error, and frequency response transmission tracking error from the test setup in a transmission or reflection test that uses those ports .

Connecting the Standard at Enhanced Response Calibration
Press Channel Next (or Channel Prev) to select the channel of which you want to perform the calibration. Confirm if your required setup is set to the channel.
Press Cal > Calibrate > Enhanced Response > Ports to select the test ports on which an enhanced response calibration is performed.
Connect an OPEN calibration standard to the output port.
Click Open to start the calibration measurement.
Disconnect the OPEN calibration standard and replace it with a SHORT calibration standard.
Click Short to start the calibration measurement.
Disconnect the SHORT calibration standard and replace it with a LOAD standard.
Click Load to start the calibration measurement.
Make a THRU connection between the two ports.
Click Thru to start the calibration measurement.
If an isolation calibration must be performed using a LOAD standard, follow the procedure below:
Connect a LOAD standard to the two test ports.
Click Isolation (Optional) to start the calibration measurement.
Click Done to terminate the enhanced response calibration process. Upon pressing the key, calibration coefficients are calculated and saved. The error correction function is also enabled automatically.
