FALLTIME A
Discussion:
The FALLTIME command sets up the instrument to mea-
sure the falltime of the input signal on Channel A. CHANNEL
A SLOPE is automatically set to
-
and the CHANNEL B
ATTEN, COUPL, SLOPE, and TERM settings are updated
to match those of CHANNEL A. The CHANNEL A input sig-
nal is internally routed through both Channels A and B input
circuits and then the 90% and 10% trigger level points are
determined and set.
The Falltime function uses the autotrigger operation to
determine the 10% and 90% points. Therefore, the trigger
levels and the minimum and maximum peak values are af-
fected by Falltime measurements.
