Quick Reference Guide
Source and measure capabilities
Laser diode source and measure:
•
Source DC current from 10µA to 1A.
•
Source current pulses from 10
µ
A to 5A with pulse widths from 500ns to 5ms;
pulse delays (time between pulses) from 20
µ
s to 500ms. (Pulse delay and width
depend on maximum duty cycle. See specifications.)
•
Measure voltage from 0.33mV to 10.5V.
•
Maximum current source DC power is 9.9W (1A @ 9.9V).
•
Maximum current source pulse power is 45W (5A @ 9V).
Photodiode detector source and measure:
•
Source bias voltage on each of two channels from 0V to ±20V.
•
Measure current on each of two channels from 0.7
µ
A to 105mA.
•
Maximum current for each bias source is 100mA.
