In response to a serial poll (SPOLL), Request Service (RQS) is reported on bit 6 of the status
byte. Otherwise, the Master Summary Status bit (MSS) is reported on bit 6. MSS is the inclu-
sive OR of the bitwise combination, excluding bit 6, of the Status Byte Register and the Ser-
vice Request Enable Register. The MSS message indicates that the scope is requesting
service (SRQ).
*TRG (Trigger)
Command *TRG
The *TRG command has the same effect as the Group Execute Trigger message (GET) or
RUN command. It acquires data for the active waveform display, if the trigger conditions are
met, according to the current settings.
