HP 16532A - Calibration

4-12. Self Cal Menu Calibrations

Note

After you touch the Start field, you can abort the calibration procedure either by touching the Cancel field, if it is available in the menu, or by touching either the Mode or Procedure fields if the continue field is still displayed on the screen.

Messages will be displayed as each calibration routine is completed to indicate calibration has passed or failed. The resulting calibration factors are automatically stored to nonvolatile RAM at the conclusion of each calibration routine.

The Self Cal menu lets you calibrate vertical sensitivity (Vert Cal) for channels 1 and 2 individually or both channels on a board simultaneously if it is a stand alone scope. Also, the Self Cal menu lets you cali- brate delay (Delay) for channel 1 and 2 separately, then Time Null for each channel separately (except channel 1 of the master board), and Ext Trig Null for the external trigger (ECL).

Calibrate Vert Cal of the Self Cal menu as follows:

1. Connect two BNC 50-Ω, 9-inch cables to the BNC tee adapter.

Note

When you touch Start, the instrument will prompt you to connect the cables to the appropriate locations on the rear panel of the module.

2.Touch the Mode field, then select Self Cal from the pop-up menu.

3.Touch the Procedure field, then select Vert Cal from the pop-up menu.

4.Touch the Channel field, then select a channel choice from the pop-up menu.

5.Touch the Start field and follow the instructions on the display.

6.After completion of vertical calibration remove the cables from the rear panel of the oscilloscope.

Calibrate Delay of the Self Cal menu as follows:

1. Obtain a BNC 50-Ω, 9-inch cable.

Note

When you touch Start, the instrument will prompt you to connect the cable to the appropriate location on the rear panel of the module.

2. Touch the Procedure field, then select Delay from the pop-up menu.
