Reinitializing Memory
! 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.
1) The easiest way to start the procedure is to use the
button combination shown during power up.
Exits re-initialization
mode without making
any changes Re-initializes all user
memory locations to
factory default contents.
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) Momentarily hold down both buttons
for about 5 seconds during power-up to
enable re-initialization.
Momentarily hold down all three video gating buttons
for about 5 seconds during power-up to start self-
calibration.
