Reinitializing Memory

(1)Momentarily hold down both buttons for about 5 seconds during power-up to enable re-initialization.

Reinitializing the generator’s

!memory erases all user created data and sets all video ampli- tude calibration factors to 0.000. This will disable the video outputs until self calibration is performed.

Self Calibration of Analog Output Levels

The video output module on the Model 822S has a built-in precision voltage reference and comparator. They permit the video output levels to be easily and accurately self calibrated using just test cables and 50 ohm terminators. The cables and terminators are not supplied as a standard accessories with the 822S.

1)The easiest way to start the procedure is to use the button combination shown during power up.

Momentarily hold down all three video gating buttons for about 5 seconds during power-up to start self- calibration.
