cally cleared when its status byte is reported. The con-
troller option can clear all events by repeatedly sending the
EVEnt? query until a zero status byte is returned. The
Device Clear (DCL) interface message may be used to
clear all events, except the power-on event.
With ROS set OFF, all service requests (except the
power-on SRO) are prevented. With the service requests
turned off, the EVEnt? query must be sent to the oscillo-
scope so that the controller can determine the oscilloscope
and event status. The controller may address the oscillo-
scope and send the ST Atus? or EV Ent? query at any time.
It is not necessary to wait for an SRO. The instrument will
return the status byte code for ST A? status bytes pending
and an event code for EVE? for events waiting to be
reported (or a O for no events to report).
Option 12
If there is more than one event of different priority lev-
els to be reported, the oscilloscope has a status byte and
event code available for each one. It does not report dupli-
cate events or more than one event of the same priority
level. Each event is automatically cleared when its status
byte or event code is reported. The Device Clear (DCL)
interface message may be used to clear all events, except
the power-on event. Querying EVEnt? until the return is
EVE O clears all pending status bytes and there is no
power -on event.
With ROS set OFF, all service requests are prevented.
With the service requests turned off, the EVEnt? query
must be sent to the oscilloscope so that the controller can
determine the oscilloscope and event status. The controller
may send the EVEnt? query at any time, and the instru-
ment will return the code for an event waiting to be
reported (or a O for no events to report). The controller can
clear all events by repeatedly sending the EVEnt? query
until a zero status byte is returned.
