Introduction to Programming The Status Model
40 Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition
Status Command Summary
*STB? returns status byte, value 0 .. +255
*ESE sets the standard event status enable mask, parameter 0 .. +255
*ESE? returns SESE, value 0 .. +255
*ESR? returns the standard event status register, value 0 .. +255
*OPC parses all program message units in the message queue, and prevents
the instrument from executing any further commands until all pending
commands are completed.
*OPC? returns 1 if all operations (scan trace printout, measurement) are com-
pleted. Otherwise it returns 0.
*CLS clears the status byte and SESR, and removes any entries from the er-
ror queue.
*RST clears the error queue, loads the default setting, and restarts communi-
cation.
NOTE: *RST does NOT touch the STB or SESR. A running measurement
is stopped.
*TST? initiates an instrument selftest and returns the results as a 32 bit
LONG.
