Specifying One or More Analog Input Channels
You can read data from one or more analog input channels using an
analog input channel-gain list. You can group the channels in the list
sequentially (starting either with 0 or with any other analog input
channel) or randomly. You can also specify a single channel or the
same channel more than once in the list.
Using software, specify the channels in the order you want to sample
them. You can enter up to 16 entries in the channel-gain list. The
channels are read in order from the first entry in the list to the last
entry in the list. Refer to
page 11 for more information about the
supported conversion modes.
The maximum rate at which the module can read the analog input
channels is 50 kSamples/s. Therefore, if you specify two analog input
channels in the channel-gain list, the maximum sampling rate is
25 kSamples/s for each channel. Likewise, if you specify 16 analog
input channels in the channel-gain list, the maximum sampling rate is
3.125 kSamples/s for each channel.
Input Resolution
The KUSB-3100 module provides a resolution of 12-bits. Note that the
resolution is fixed; it cannot be programmed in software.
