Calibration Procedures 3
Adjust the ADC
3 34410A/11A: Select the front panel input terminals. If using a single
shorting block, install the block on the front panel input terminals.
L4411A: Install the shorting block on the input terminals.
4 Select the ADC adjustment mode (see “Selecting the Adjustment Mode” on
page 78 or, for the remote interface page 79).
5 The display will show the ADC calibration steps as they progress. The
ADC adjustment requires approximately 2 minutes to complete. When
