Description
The Agilent E1418A 8/16-Channel
D/A Converter is a C–size, 1-slot,
register-based VXI module. It
consists of 8 or 16 fully independent, isolated or non-isolated,
16-bit D/As. Each channel can
be set to voltage or current mode
with local or remote sensing
on voltage outputs. All outputs
can be updated with registerlevel programming to allow fast
backplane access. Each channel
can be updated individually, or
by using the internal data buffer,
synchronized so that all channels
change simultaneously. The
channel output mode is set with
jumpers in the terminal block
for each channel or by register
programming. Each D/A converter
can be calibrated without removal
through software commands and
use of the terminal block CALBUS
in conjunction with a 5.5-digit
multimeter. The on/off terminal
block has standard screw terminals for field wiring.
Refer to the Agilent Technologies
Website for instrument driver
availability and downloading
instructions, as well as for recent
product updates, if applicable.
Fast Updates
All outputs can be updated with
register-level programming to
allow fast backplane access. Rates
are limited by controller speed
and analog settling time. Each
channel can be updated individually, or by using the internal
data buffer, synchronized so that
all channels change at the same
time. The channel output mode is
set with jumpers in the terminal
block for each channel or by
register programming.
In-place Calibration
Each D/A converter can be calibrated without removal through
software commands and use
of the terminal block CALBUS
in conjunction with a 5.5-digit
multimeter. In addition, a built-in
self-test command provides a
high level of confidence that the
module is operating properly.
