PAS 9716/AO : 16 Channel 16 Bit VME
Analog Output Card
Links to printable product info:
Precision Analog System's 9716/AO card provides sixteen analog
output channels with 16 bit resolution on a 6U VME format.
Each channel has a +/- 10 Volt output range with 5 mAmps of output
current. Settling time is typically 6 uSec for a zero to full
scale change of the output voltage.
By using 16 bit Digital to Analog Converters (DACs), this card provides
sixteen times the resolution of cards designed with 12 bit DACs.
Requirements of having several jumper selectable output ranges are
eliminated with this design approach, since the 16 bit card has
higher output resolution with the +/- 10 Volt range than a 12 bit
card has with a +/- 2.5 Volt output range.
Each DAC contains a Channel Data Register and a DAC Register.
This allows all Channel Data Registers to be loaded, and then all
the DACs to be updated simultaneously. Normally the output of a
DAC will be updated when the appropriate Channel Data Register is
written unless the simultaneous update feature is enabled.
All channels have gain and offset adjustments that are set at the
factory to +/- 1 LSB. The remaining error source is the linearity
error of the DACs, which is +/- 1 LSB over temperature.
The PAS 9716/AO card's address is jumper selectable and uses a 256
byte block of memory that can be mapped anywhere in the full 32
bits of VME space. The card can be configured to be a A32,
A24 or A16 compatible with pluggable jumpers. Individual output
channels can be written with 16 bit writes to a Channel's Data Register,
or two sequential channels can be written simultaneously with a
single 32 bit write. The output data is 2's complement. A
control register and board identifier PROM are also provided.
Two output amplifier cards are available for use with the 9716/AO
card. Each amplifier card has 16 channels and is pin compatible
with the 9716/AO. The PAS 9416/AO amplifier provides up to +/- 35
Volts or 20 mAmps of output drive, and the PAS 9418/AO can supply
up to +/- 85 Volts or 50 mAmps to the output load.
