Two Port Network Analyzer Calibration

The Two Port Network Analyzer Calibration performs a two port calibration with a mechanical calibration kit or an electronic calibration module (E-Cal) and saves the state for later use in the VSWR and 30 dB Attenuator Insertion Loss tests. This calibration is only applicable for the N848xB UUT power sensors.

Ensure that the adapters and cables remain connected to the PORT 1 and 2 of the network analyzer until the 30 dB Attenuator Insertion Loss and VSWR tests are completed.

E-Cal Usage

An E-Cal may be used for the Two Port Network Analyzer Calibration instead of a mechanical calibration kit. When using the E-Cal, connect it to the network analyzer using a USB cable. Before using the E-Cal, ensure that the ready light has turned to green on the unit. When mapping the E-Cal in the TME, the serial number should be a 5-digit number with no letters. If there is no 5-digit serial number printed on your unit, follow these instructions using your network analyzer to locate your serial number.

  1. Connect the E-Cal to the network analyzer using a USB cable.
  2. Press the Cal button.
  3. Press the Cal Wizard key.
  4. Choose Guided Cal.
  5. Choose 2 Port Cal.
  6. You should see the model number of your E-Cal followed by the 5-digit serial number in the Cal Kits box on the screen.
