*CLS (No Query Form)
Clears the digitizing oscilloscope status data structures.
Status and Error
DESE, *ESE, *ESR?, EVENT?, EVMsg?, *SRE, *STB?
*CLS
*CLS
The *CLS command clears the following:
H the Event Queue
H the Standard Event Status Register (SESR)
H the Status Byte Register (except the MAV bit; see below)
If the *CLS command immediately follows an <EOI>, the Output Queue and
MAV bit (Status Byte Register bit 4) are also cleared. MAV indicates informa-
tion is in the output queue. The device clear (DCL) GPIB control message will
clear the output queue and thus MAV. *CLS does not clear the output queue or
MAV. (A complete discussion of these registers and bits, and of event handling
in general, begins on page 3–1.)
*CLS can suppress a Service Request that is to be generated by an *OPC. This
will happen if a hardcopy output or single sequence acquisition operation is still
being processed when the *CLS command is executed.
