Analog output features

An analog output (D/A) subsystem is provided on the KPCI-3102 and KPCI-3104 boards only.
This section describes the following features of the D/A subsystem:

•

Output resolution

•

Analog output channels

•

Output ranges and gains

•

Conversion modes

•

Data formats and transfer

•

Error conditions

Output resolution

lists the output resolutions supported by the KPCI-3102 and KPCI-3104 boards. The

resolution is fixed for each board type; therefore, it cannot be programmed in software.

Analog output channels

The KPCI-3102 and KPCI-3104 boards support two serial, multiplying, DC-level analog output
channels (DAC0 and DAC1). Refer to

“Installation and Configuration”

tion on how to wire analog output signals to the board using the screw terminal panel. You con-
figure the channel type as differential through software.

Within each DAC, the digital data is double-buffered to prevent spurious outputs, then output as
an analog signal. Both DACs power up to a value of 0V ±10mV. Resetting the board does not
clear the values in the DACs.

The KPCI-3101–4 Series board can output data from a single analog output channel only. Spec-
ify the channel for a single value analog output operation using software. Refer to

put conversion modes”

on this page for more information on single value operations.

Output ranges and gains

For the KPCI-3102 and KPCI-3104 board, you can specify one of the following ranges for each
DAC using software: ±10V, 0 to 10V, ±5V, or 0 to 5V.

In software, specify a gain of 1 for analog output operations.
