For input channels and measured output channels, the current value reported by the CTC100 is
the most recent ADC reading with the sensor calibration and lowpass, difference, etc. filters
applied. This value may be different than the most recently-logged point, which is the value that
appears on the plot and in general corresponds to an average of several ADC readings.

C hannel.alarm submenu
All
channel. alarm
instructions can only be applied to input channels. Issuing any of the
following instructions for an output channel results in an assembly-
error.
Channel. alarm.lag 0
A non-zero lag prevents the alarm from triggering until the signal has continuously exceeded the
alarm limits for the indicated number of seconds.
Channel. alarm.latch { No, Yes }
Selecting No Yes makes the alarm latching. A
momentary alarm only sounds while the input signal exceeds the alarm limits; a latching alarm,
once triggered, continues to sound until the status or mode is set to off.
Channel. alarm.min 0.0
Channel. alarm.max 0.0
These instructions set the alarm thresholds. The alarm is triggered whenever the signal exceeds
these values. The thresholds are specified in the same units in which the channel value is displayed.
Channel. alarm.mask?
Returns a 32-bit integer that indicates which bit in the Alarm Status Register this alarm sets
whenever it is tripped; for example, a mask value of 1 indicates that bit 0 is set; 2 indicates that bit
1 is set; 4 indicates that bit 2 is set; and so on. The Alarm Status Register is part of the GPIB status
reporting system; see the IEEE488 commands section for more information.
Errors: attempting to change the value of the mask produces a run-
error.
Channel. alarm.mode { Off, Level, Rate /s }
Enables or disables the alarm. The alarm can be programmed to trigger either when the level of
the signal or its rate of change exceeds the thresholds. The rate of change is calculated over two
successive A/D conversions and is therefore susceptible to noise; i
lowpass filter to reduce noise.
Channel. alarm.mute { True, False }
Turns off the alarm sound. Has no effect on the alarm relay. The alarm stays muted until the
alarm condition disappears.
Channel. alarm.output { channel name }
Associates an output channel with the alarm. This output is shut off whenever the alarm is
triggered; that is, the output is set to zero and its feedback loop (if any) is disabled. Once the
output returns to its previous value and the feedback loop
