CURRENT SOURCE NOTES
1 All values relate to a one-hour warm-up period.
2 Accuracy is 0.15% above 2.5 A after 1-hour warm-up period.
3 Over any 1-hour period, half-scale output.
4 Over any 24-hour period, half-scale output.
5 Measured optically, evaluating noise intensity of a laser diode into a
photodetector with 150 kHz bandwidth.
6 Maximum output current transient resulting from normal operational
situations (e.g. power on-off, current on-off), as well as accidental
situations (e.g. power line plug removal).
7 Maximum output current transient resulting from a 1000 V power-line
transient spike. Tested to ILX Lightwave Technical Standard
#LDC-00196. Request ILX Application Note #3, “Protecting Your Laser
Diode”.
