Basic Operation
Model 2520 User’s Manual
Programming example
summarizes the command sequence for basic source and measure configuration.
NOTE
See
for complete test procedures.
These commands set up the Model 2520 as follows:
•
Laser diode voltage measurement range and polarity: 10V, positive.
•
Photodiode measurement polarity: negative (both detectors).
•
Laser diode source: 0.5A range, +0.5A amplitude, 5V voltage limit, positive
polarity.
•
Laser diode source mode: pulse, delay = 100
µ
sec, width = 10
µ
sec, low I = 10mA.
•
Detector #1 source: +20V amplitude.
•
Detector #2 source: +10V amplitude.
