Operation Status Register
Requirement: To perform a single sweep from 1 MHz to 10 MHz in 1 MHz steps with
133 ms between each step at 1V rms. Monitor the Operational Status bit that indicates
that the sweep is in progress.

STATUS:OPER:COND?
<- Instrument responds with a value that has bit 4 set, i.e., the value 8 wait
for 5 seconds
STATUS:OPER:COND?
<- Instrument responds with a value that has bit 0 clear, i.e., the value 0
SRQ Operation and Error Handling
Requirement: To generate a service request from the Instrument when it detects a
problem.

*CLS
INST SINE
*SRE 255
*ESE 255
UNIT:POWer DBM
POW 1
<- this command would be executed by the Instrument
POW 1E6
<- The user meant to set up 1MHz, with FREQ 1E6
<- Instrument generates an SRQ
*STB?
<- Instrument responds with the value 32 (decimal). This indicates there is
Event flag
*ESR?
<- the Event Register returns 15 (decimal) meaning there is an execution
error.
SYST:ERR?
<- Instrument returns the message from the error queue
<- -222”Data out of range;Value too large”
<- indicating the problem with the last command
