The resistance-programming
(100% rated output power) / 5 kΩ, with input at Pin 34 (PPRG_ISOUR) and return to
Pin 18 (RTN_PRG). Refer to Figure 8-5. 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 power, as follows:
Pout = R * (100% rated output power) / 5 kΩ), with R in kohms.
Full Scale power 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
Power programming send below command
SOUR:POW:PROG:FSCR 10
Then the transfer function for output power, as follows:
Pout = R * (100% rated output power) / FSC kΩ), with R in kohms.
