IEEE Common Command s
The number 4 (P in the preceding query response format) means there are 4
numbers that make up the size of the data that follows . In this example,
2031 bytes will follow the number 4 (42031).
2031 and 2016 (QQQ and MMM in the preceding query response format )
represent data size in bytes.
The state can be changed by sending this block of data to th e
instrument after removing the size information :
SYST :SET #NMMM<state data >
Operation Complet e
*oPC
*OPC?
Sets bit 0 in the standard event status register to "1" when all pending
operations have finished.
The query stops any new commands from being processed until th e
current processing is complete . Then it returns a " 1", and the program
continues . This query can be used to synchronize events of othe r
instruments on the external bus.
*OPC and *OPC? are currently effective only when immediately
preceded by either the : INITiate : IMMediate or a : CALibration
command.
Query Instrument Options
This function is provided in the ESA SCPI language reference in th e
SYSTem subsystem under : SYSTem : OPTions? .
Recall
*RCL <register>
This command recalls the instrument state from the specifie d
instrument memory register.
Range : Registers are an integer, 0 to 127
Remarks: See also commands :MMEMory : LOAD : STATe and
:MMEMory :STORe :STATe
If the state being loaded has a newer firmware revisio n
than the revision of the instrument, no state is recalle d
and an error is reported.
If the state being loaded has an equal firmware revisio n
than the revision of the instrument, the state will be
loaded.
