Analog Reference source is selected as Resistance and programming mode of output
Voltage as external by sending following SCPI command.
SOUR:ANALOG:PROG:SOUR CURR
SOUR:VOLT:PROG EXT
The resistance-programming
(100% rated output voltage) / 5 kΩ, with input at Pin 3 (VPRG_ISOUR) and return to
Pin 18 (RTN_PRG). Refer to Figure 8-4. An internal current source, factory-set at 1
mA, from Pin 20 is utilized to drive the resistance. This produces a transfer function
for output voltage, as follows:
Vout = R * (100% rated output voltage) / 5 kΩ), with R in kohms.
Full Scale voltage programming resistance can be modified from default 5kOhms to
any other value, from 2 kOhm to 10 kOhm. For example, To set 10 kOhms as full scale
for Voltage programming send below command
SOUR:VOLT:PROG:FSCR 10
Then the transfer function for output voltage, as follows:
Vout = R * (100% rated output voltage) / FSC kΩ), with R in kohms.
