PC Card-EZ
(DT7100 Series)
Easy-to-Use, High Accuracy PC Cards
for Data Acquisition
PC Card-EZ
is a series of high accuracy,
multifunction data acquisition PCMCIA
cards. Capabilities include one or two
12-bit, 100 kS/s A/D converters,
up to 16 input channels, and two
50 kS/s, 12-bit DACs (not available
on all models). Windows
95 software
support is provided by HP VEE,
DTx-EZ,
DT-LV Link
and the
DataAcqSDK.

Notes to table at left:
* Exceeding these throughputs may result in inaccurate dynamic
measurements.
**In simultaneous mode, both A/D converters operate at the same
time, sampling two channels at once. Each A/D converter is
capable of 100 kS/s, for an aggregate throughput of 200 kS/s.
In pseudo-differential mode, both the signal +in and –in are
connected to separate multiplexer channels. However, unlike
conventional differential circuits, only the +in side is sampled.
This requires that the –in side remain stable to within ±0.5 LSB
during conversion.
