Description
Active
Detector
(read only)
Determines the active detector. There is only one
detector possible for this instrument.
Raw Count
Time
0 604800
Instructs the device to take a raw count for a
specific amount of time. Results will be available
in the Raw Counts parameter when the count
time reaches 0.
Raw
Counts
(read only)
Raw count result with no modification (no dead
time, etc.). Results available when Raw Count
Time reaches 0.
Revision (read only) Displays the revision number of the circuit board.
Instrument
Discrimi-
nator
Channels
(read only)
Displays the number of channels the instrument
is capable of. This instrument is only capable of 1
channel.
