1. Before attempting to verify series operation, perform the power-on
test of the individual modules per the section, Power-On Check,
and then the standalone operation test per section, Standalone
Configuration.
2. Connect the outputs for series operation per the section, Series
Configuration. Ensure that the outputs and remote sense are
appropriately hardwired prior to issuing any of the series-
connection SCPI commands.
3. Connect appropriate instrumentation for measuring the output
voltage and current, as well as a load.
4. Configure the modules into a series 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:SER [n1],[n2]
5. Verify that the series group has been properly set up with the
following command. The response to the query is a listing of the
series group, the master module of the series group, and the slave
module of the series group. For example, a group of modules with
a master in slot 3 and a slave in slot 4 would return the following
parameters: 2003,1003,1004. The parameter,
[2000+n1] , is the
sum of 2000 and the slot number of the master module.
SYST:GRO:CAT:SER?
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,
[2000+n1] , is the sum of 2000 and the slot number of
the master module. For example, if the master module is located
in slot 1, the parameter value would be 2001.
OUTP[2000+n1]:ISOL 1
OUTP[2000+n1]:SENS 1
OUTP[2000+n1]:STAT 1
SOUR[2000+n1]:CURR <fval>
SOUR[2000+n1]:VOLT <fval>
7. Measure the output voltage and current with the external
instruments.
