chan
(Return current channel parameters)
chan
is the channel number. Range: 0 to 31.
low
is the low mass. Range: 1 to 319.
high
is the high mass. Range: 2 to 320.
dwell
is the sample dwell time. Range: 3, 4, 5, 10, 15, 30,
60, 120, 250, 500, 1000,
2000, 4000, 8000, 16000
(in
milliseconds)
samples
is the samples per AMU. Range: 4 to 15.
input
is the analog or digital input channel on the I/O Option board
gain
is an optional parameter for sample gain. Defaults to 1.0 if not set.
offset
is an optional parameter for sample offset. Defaults to 0 if not set.
offset2
is an optional parameter for sample offset. Defaults to 0 if not set.
The data values are modified by the following formula:
NEW_VALUE = ((VALUE +
offset
) x
gain
) +
offset2
Returns
If just chan is supplied, then one of the above strings is returned (in-
cluding gain, offset, offset2).
