1-Port Calibration (reflection test)

Other topics about Basic Calibration

Overview

In 1-port calibration, calibration data are measured by connecting an OPEN standard, a SHORT standard, and a LOAD standard to the desired test port. This calibration effectively eliminates the frequency response reflection tracking error, directivity error, and source match error from the test setup in a reflection test using that port.

S-Parameter Measurement

  1. 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.

  2. Press Cal > Calibrate > 1-Port Cal > Select Port.

  3. Select a test port (and corresponding S parameter) on which 1-port calibration will be performed.

  4. Connect an OPEN calibration standard to the selected test port (connector to which the DUT is to be connected).

  5. Click Open to start the calibration measurement.

  6. Connect a SHORT calibration standard to the selected test port (connector to which the DUT is to be connected).

  7. Click Short to start the calibration measurement.

  8. Connect a LOAD calibration standard to the selected test port (connector to which the DUT is to be connected).

  9. Click Load to start the calibration measurement.

  10. Click Done to terminate the 1-port calibration process. Upon pressing this key, calibration coefficients are calculated and saved. The error correction function is also enabled automatically.

Gain-Phase Measurement

  1. 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.

  2. Press Cal > Calibrate > 1-Port Cal > Select Port > GP Port.

  3. Connect an OPEN calibration standard in the position specified in the figure below.

  4. Click Open to start the calibration measurement.

  5. Connect a SHORT calibration standard in the position specified in the figure below.

  6. Click Short to start the calibration measurement.

  7. Connect a LOAD calibration standard in the position specified in the figure below.

  8. Click Load to start the calibration measurement.

  9. Click Done to terminate the 1-port calibration process. Upon pressing this key, calibration coefficients are calculated and saved. The error correction function is also enabled automatically.
