5730A
Operators Manual
Commands
Table 6-4 summarizes the commands by function. Table 6-5 provides protocol details of
the remote commands. Table 6-6 provides protocol details of the three special commands
available for serial remote control only. The commands duplicate almost all activities that
can be initiated from the front panel in local operation. Separate headings for each
command in the tables provide the parameters and responses (if any), and an example for
cases in which the parameters are not self-explanatory.
Multiple Commands
Controllers may send commands all at once, or one at a time. To set the output to 100 mV
dc and then place the 5730A Calibrator into operate, two separate commands may be
used:
Or enter it as a compound command on a single line:
Coupled Commands
When a compound command follows another command, there is a possibility that a fault
can occur because of the action of the first command. Such commands are called coupled
commands. An example of coupled commands that cause a fault is:
followed by the compound command:
The second command causes a fault because when the 5730A Calibrator encounters
"OUT 100V", it is interpreted as 100V, 1 MHz, which is out of range of the Calibrator.
If only the second compound command was sent, there would have been no fault and the
Calibrator would be set to 100 V at 100 Hz.
Another example is:
followed by:
In this case, when the Calibrator interprets the first half of the second command, it causes
an error since the previous command locked the range on 2.2 V.
Any command that affects the state of the output is a coupled command, for example
order-dependent. These commands include all the following: *RST, BOOST,
BTYPE, CAL_CHK, CAL_REF, CAL_STORE, CAL_ZERO, CUR_POST,
DIAG, EXTGUARD, EXTSENSE, FORMAT, INCR, LIMIT, MULT,
NEWREF, OFFSET, OPER, OUT, PHASE, PHASELCK, PHASESFT,
RANGELCK, RCOMP, REMOTE, LOCAL, LOCKOUT, SCALE, STBY,
WBAND, CAL_RNG. Make sure to use appropriate sequences when these commands are
used.
