Remote Programming BY VOLTAGE

8.3.2
Remote Analog reference source of the Output Voltage, Current and Power can be
selected as Voltage by sending the following SCPI Command:
SOUR:ANALOG:PROG:SOUR VOLT
8.3.2.1 R C
EMOTE URRENT
Analog Reference source is selected as Voltage and programming mode of output
Current as external by sending following SCPI command.
SOUR:ANALOG:PROG:SOUR VOLT
SOUR:CURR:PROG EXT
The DC voltage source is connected between Pin 19 (IPRG_VSOUR) and the return Pin
18 (RTN_PRG), refer to Figure 8-6. Default FSC voltage value is 10V, where 10V
corresponds to 100% output current. The corresponding voltage-programming
coefficients for output current are (100% rated output current) / FSC VDC. This produces
transfer functions for output current, as follows:
Iout = Vdc * (100% rated output current) / 10 VDC), with Vdc in volts, or
Iout = Vdc * (100% rated output current) / FSC VDC), with Vdc in volts.
The Full-Scale voltage value can be modified to any voltage between 2V to 10V
from below SCPI command. For example, To set 5V as full scale for Current
programming send below command
SOUR:CURR:PROG:FSC 5
