1. Stability specifications are measured at half-scale output, after a one hour warm-up period.
2. Extrapolated from resulting intensity fluctuations of a laser diode, measured optically with a 150 kHz bandwidth photodetector.
3. The instrument contains a circuit which will turn off the output if a transient is detected.
4. Maximum output current transients resulting from normal operational situations (e.g., power on-off) as well as accidental situations
(e.g., power line plug removal)
5. Maximum output current transients resulting from a 200 V power-line spike.
