3.6.2 Remote Power Programming by Voltage Source
The DC voltage source is connected between Pin 33 (PPRG_VSOUR) and the return
Pin 18 (RTN_PRG) and Analog Reference source is selected as Voltage from the front
Panel. Refer to Figure 3-105.
The Full-Scale voltage value can be modified to any voltage between 2V to 10V from
front panel screen. Refer to Section 3.1.8.3. Default FSC voltage value is 10V, where
10V corresponds to 100% output power. The corresponding voltage-programming
coefficients for output power are (100% rated output power) / FSC VDC. This produces
transfer functions for output power, as follows:
Pout = Vdc * (100% rated output power) / 10 VDC), with Vdc in volts, or
Pout = Vdc * (100% rated output power) / FSC VDC), with Vdc in volts.

3.6.3 Remote Power Programming by 4-20mA Source
A 4-20mA current source is connected between Pin 33 (PPRG_VSOUR) and the
return Pin 18 (RTN_PRG) and select the Analog Reference Source as 4-20mA in front
panel. Refer to Figure 3-106.
