seconds to HOLD.
Arming:
Rear panel ARM (ON-OFF) switch.
Refer to operation for details.
Blanking:
Unwanted zeros to left of most-
significant-digit are suppressed.

PROGRAMMABLE OPERATION
(CHANNELS A AND B)
Includes independent selection of coupling,
trigger slope, trigger level, and attenuator for
each channel. Separate/Common A switch is
programmable. Also, an invert feature switches
Channels A and B; useful in all functions except
Ratio B/A.
Trigger level is programmable in 10 mV steps
in X1; 100 mV in X10; IV in X100.
Trigger level accuracy under remote control:
X1:
±35 mV
X10:
±350 mV +2% of trigger level
X100:
±3.5V +2% of trigger level
