Analog Input Features
This section describes the following features of analog input (A/D)
operations on the KUSB-3100 module:
• Analog input channels, described on this page;
• Input resolution, described on page 8 ;
• Input ranges and gains, described on page 9 ;
• Input sample clock sources, described on page 10 ;
• Analog input conversion modes, described on page 11 ;
• Input triggers, described on page 13 ;
• Data format and transfer, described on page 14 ; and
• Error conditions, described on page 15 .
Analog Input Channels
The KUSB-3100 module provides eight single-ended analog input
channels. The module can acquire data from a single analog input
channel or from a group of analog input channels.
The following subsections describe how to specify the channels.
Specifying a Single Analog Input Channel
The simplest way to acquire data from a single analog input channel
is to specify the channel for a single-value analog input operation
using software; refer to
page 11 for more information about
single-value operations.
You can also specify a single channel using the analog input
channel-gain list, described in the next section.
