3.2.4 Programming the forward current (IFWD)
NOTE
This command always affects port 1, so you do not need to select the port
1 first. This command is
only
available for a PDA8000
with the option
PDA8000-FWD
Programming:
":IFWD:SET <NR3>"
Programs the forward current of port 1
Reading:
":IFWD:SET?"
Reads the forward current of port 1
[:IFWD:SET
<NR3><LF>]
":IFWD:MIN?"
Reads the allowed minimum forward current of
port 1
[:IFWD:MAX
<NR3><LF>]
":IFWD:MAX?"
Reads the allowed maximum forward current of
port 1
[:IFWD:MIN
<NR3><LF>]
3.2.5 Reading the photo diode current (IPD)
NOTE
Please first select the desired port with the command ":PORT"
Programming:
":IPD:MEAS <NR1>"
Programs the photo current to be a measurement
value for “ELCH” on output string position <NR1>
(1...8)
Reading:
":IPD:ACT?"
Reads the actual photo diode current
[:IPD:ACT
<NR3><LF>]
":IPD:MIN_R?"
Reads I
PD
– ADC = 0000
[:IPD:MIN_R
<NR3>]
":IPD:MAX_R?"
Reads I
PD
– ADC = FFFF
[:IPD:MAX_R
<NR3>]
