## Procedure for TL calibration

1. Select the desired calibration frequency in the field Cal. freq.

2. Connect a scope together with a 50Ohm terminator to the DUT connector. Be sure to connect the T-connector to the scope to get correct readings.

   The image on the scope should like this:

   Enter the measured Uss voltage into the field Measured Uss:

3. Enter the attenuation of the desired pad into the field Cal.Attenuator:

4. Connect a cable between DUT and DET connector

   Press the Loop-Button

5. Connect the attenuator pad together with the loopcable between the DUT and DET connector.

   Press the Atten.-Button

6. Now the OK-Button is enabled and the new calibration values are shown in Calibrated fields

7. Press the OK-Button to use the new calibration values and close the dialog.

8. Press the Cancel-Button to keep the initial calibration values and close the dialog.
