appropriately hardwired prior to issuing any of the paralleling SCPI
commands.
3. Connect appropriate instrumentation for measuring the output
voltage and current, as well as a load.
4. Configure the modules into a parallel group with the following
command, where <n1> is the master module of the group.
Although the example is for two modules, it could be extended to
a greater number by listing additional parameter slot numbers,
[n] .
SYST:GRO:DEF:PAR [n1],[n2]
5. Verify that the parallel group has been properly set up with the
following command. The response to the query is a listing of the
parallel group, the master module of the parallel group, and the
slave module of the parallel group. For example, a group of
modules with a master in slot 3 and a slave in slot 4 would return
the following parameters: 1003,3,4. The parameter,
[1000+n1]
,
is the sum of 1000 and the slot number of the master module; the
master module is the left-most module of the parallel group.
SYST:GRO:CAT:PAR?
6. Turn on the isolation and remote sense relays, turn on the output
converters, and program full-scale voltage and current with the
following commands. The parameter,
<fval>
,
is the full-scale
output voltage or current of the particular model under test. The
parameter,
[1000+n1] , is the sum of 1000 and the slot number of
the master module; the master module is the left-most module of
the parallel group. For example, if the master module is located in
slot 1, the parameter value would be 1001.
OUTP[1000+n1]:ISOL 1
OUTP[1000+n1]:SENS 1
OUTP[1000+n1]:STAT 1
SOUR[1000+n1]:CURR <fval>
SOUR[1000+n1]:VOLT <fval>
7. Measure the output voltage and current with the external
instruments.
8. Ensure that the actual values of the output parameters are within
specifications of the programmed values.
9. Query the values of the output parameters with the following
commands:
MEAS[1000+n1]:VOLT?
MEAS[1000+n1]:CURR?
10. Ensure that the readback values of the output parameters are
within specifications of the actual values.
