Remote Operation
Use Commands 5
5-31
before they have completed execution.
In Chapter 6, the command shows a checkbox for overlapped commands.
The overlapped commands, but not the scope commands, are:
DBM OPER TSENS_TYPE
DC_OFFSET OUT WAVE
DPF PHASE ZCOMP
DUTY RANGELCK
EARTH *RST
HARMONIC RTD_TYPE
INCR STBY
LCOMP TC_OFFSET
LOWS TC_OTCD
MULT TC_REF
OLDREF TC_TYPE
You can use the command *WAI to wait until the overlapped command has completed
execution before you do the subsequent command. For example,
OUT 1 V, 1 A, 60 HZ; *WAI
You can also use the status commands *OPC and *OPC? to find completion of
overlapped commands. (See “Check 5502A Status.”)
Sequential Commands
Commands that start immediately are sequential commands.
In Chapter 6, the command shows a checkbox for sequential commands.
Most of the commands are sequential.
Commands where a Calibration Switch is Necessary
For the subsequent commands, the rear panel CALIBRATION switch must be in the
ENABLE position:
CLOCK (when setting date but not time)
FORMAT ALL
FORMAT CAL
*PUD
If you try to use these commands with the CALIBRATION switch in the NORMAL
position, an error is logged into the error queue. (Or it returns the error message if in the
RS-232 Terminal Mode.)
