The PDMEAS command is used to measure the ￿atness of an external photodiode. The diode-￿atness correction factors are not included in the ￿atness correction.

When the PDMEAS ON parameter is used, the following conditions are satis￿ed:

￿Trace A 0 B is turned on.

￿Internal, optical switch is set to external.

￿Diode ￿atness correction factors are turned o￿.

￿External diode is selected.

￿IN and OUT indicator LEDs are turned on.

￿DET IN indicator LED is turned o￿.

When the PDMEAS OFF parameter is USED, the following conditions are satis￿ed:

￿Trace A 0 B is turned o￿.

￿Internal, optical switch is set to external.

￿Diode ￿atness correction factors are turned on.

￿Internal diode is selected.

￿IN and OUT indicator LEDs are turned on.

￿DET IN indicator LED is turned on.
