Parameters
Voltage/Current Range
Select the voltage/current range and data format for each channel.
Conversion Rate
Select a rate at which to convert data from analog to digital (A/D) for each channel. The valid rates are: 150 Hz, 300 Hz, 600 Hz, or 1200 Hz.
Low Pass Time Constant
Select a low pass filter option for each input channel. The valid options are: 100 ms, 500 ms or 1000 ms.
low pass filter
A digital device that provides noise rejection for input signals. This device is programmable and has eight filter frequency options for each channel. A low frequency provides the most noise rejection. A high frequency provides the least noise rejection and a faster step response time.
Real Time Sample
The rate at which the module collects the most recent output of the converter that is later sent off to the adapter. Select a value in milliseconds. The valid range is 0-30000 in 5 ms intervals.
Interleave Module Interrupts
Do not check the Interleave Module Interrupts check box unless you know you have a specific use for this option. The Interleave Module Interrupts feature is useful only in limited circumstances and can only be enabled when you configured a module’s Conversion Rate to 1200 Hz, Low Pass Time Constant to None, and Real Time Sampling period to 0 for ALL channels on the module.
