3 - 26 USING THE COMBISCOPE INSTRUMENTS
Only in the single-shot and multiple-shot trigger mode (INITiate:CONTinuous
OFF), the bits 3 (SWEeping) and 5 (Waiting for TRIGger) in the OPERation status
are valid. Also the Operation Complete bit (OPC bit 0) in the standard Event
Status Register (ESR) is valid. This allows you to detect whether the instrument
is armed (initiated), triggered (busy with acquisition), or finished with the last
acquisition, i.e., ready for the next acquisition.

Commands: CONFigure:AC Configures instrument and sets
single-shot mode.
MULTIPLE-SHOT MODE (TB MODE - multi):
The bits 3 (SWEeping) and 5 (Waiting for TRIGger) also reflect the acquisition
status, when the "SINGLE ARM'D" button on the front panel was pressed.
Commands: SYSTem:KEY 101 Performs AutoSet.
DISPlay:MENU TBMode Displays TBMODE menu.
SYSTem:KEY 1 Sets INIT:CONT OFF and sets
multiple-shot mode.
