1. All values are contingent upon a 60-minute warm-up period with the output turned-on.
2. Over any 1-hour period, half-scale output.
3. Over any 24-hour period, half-scale output.
4. Measured optically, evaluating noise intensity of a laser diode into a photodetector with 150 kHz bandwidth.
5. 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).
6. Maximum output current transient resulting from a 1000V power-line transient spike. Tested to ILX Lightwave Technical
Standard #LDC-00196. Request ILX Application Note #3.
7. Maximum monitor photodiode current drift over any 30 minute period. Assumes zero drift in responsivity of photodiode.
Modulation input is 50 Ω terminated inside the mainframe.
8.
50% modulation at mid-scale output, 0.5 Ω load. High bandwidth mode.
9.
10. Responsivity value is user-defined and is used to calculate the optical power.
11. Four wire voltage measurement. Voltage measurement accuracy while driving calibration load. Accuracy is dependent
upon load and cable used.
