RIGOL Chapter 2 Constant Voltage Tests
DP800 Performance Verification Manual
of this channel (please refer to Table 2-22).
/*Select CH1 as the current channel and set the
voltage and current of this channel to 8V and
Notes:
The above command is only applicable to the multi-channel models of
DP800. You can also send the :INST:NSEL 1 (or :INST CH1) command
to select CH1 as the current channel, the :SOUR1:VOLT 8 command to
set the voltage of CH1 to 8V and the :SOUR1:CURR 5.3 command to
set the current of CH1 to 5.3A.
For the single channel model with multiple ranges of DP800 series
(DP811A), you can send the :OUTP:RANG P20V (or :OUTP:RANG LOW,
or :VOLT:RANG P20V, or :VOLT:RANG LOW) command to select Range1
as the current range and then send the :VOLT 20 command to set the
voltage of the channel to 20V and the :CURR 10.5 command to set the
current of the channel to 10.5A.
2) Make sure that the power supply is in CV mode. Read and record the
reading (U
3
) of the multimeter.
3) Send the :MEAS:VOLT? CH1 command via the remote interface; read and
record the returned voltage value U
4
of the query command.
4) Calculate the CV programming accuracy (|U
3
-U
R
|) and the CV readback
accuracy (|U
4
-U
3
|). Compare them with the specified specifications in Table
2-22. Wherein, U
R
is the rated output voltage of the channel under test.
5) Send the following command via the remote interface to disable the output
of the channel under test.
/*Disable the output of CH1*/
5. Repeat steps 1 to 4 to test the CV programming and readback accuracy of CH2
and CH3 until finishing the CV programming and readback accuracy tests of all
channels.
Note: For the multi-channel models of DP800 series, please replace the “CH1”
in the remote commands in steps 3 and 4 with “CH2” or “CH3” to select and set
the corresponding channel.
