Discussion:
The RISET'IME command sets up the instrument to mea-
sure the risetime of the input signal on Channel A. CHAN-
NEL A SLOPE is automatically set to
+
and the CHANNEL
B ATTEN, COUPL, SLOPE, and TERM settings are updat-
ed to match those of CHANNEL A. The CHANNEL A input
signal is internally routed through both Channels A and B
input circuits, and then the 10% and 90% trigger level points
are determined and set.
The Risetirne function used 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 Risetime measurements.

Discussion:
The RQS command is a global control for assertion of
SRQ by the DC 5010. When RQS is OFF the DC 5010 will
not assert SRQ under any circumstance. When RQS is ON
the DC 5010 is allowed to assert SRQ under appropriate
circumstances; i.e., errors, operation complete, etc.
The ERROR? query can be used while RQS is OFF to
see if any SRQ type conditions have occurred.
SRQ will be asserted for any previously unreported SRQ
event when RQS is turned ON after being OFF.
The power-on initial setting is "RQS ONn.
