E1418A Datasheet, PDF (2/4 Pages) Agilent(Hewlett-Packard) – 8/16-Channel D/A Converter

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 indi-
vidually, 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 cali-
brated 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.
Choice of Connectors
The easy-to-use on/off terminal
block, a feature of QUIC, comes
with standard screw terminals
for field wiring. Optional crimp
and insert or ribbon cable connec-
tors are available. Each channel
contains a programmable output
disconnect relay to open or close
the channel.

Software commands, external trigger inputs, or
TTL backplane trigger lines provide a choice of
synchronizing event. Each individual channel can
be updated by software command or all channels
can be updated at the same time based upon a
software or hardware trigger.
