Resistor-programmed gain from x1 to x100 is available
on PC-414E with increased settling delay at higher gain.
Total throughput includes MUX settling time after
changing the channel address, S/H acquisition time to
rated specifications, A/D conversion, and FIFO transfer.
Total throughput is not delayed by host software
whenever the FIFO is not full.
THD test conditions are:
A. Input freq.
B. Generator/filter THD is -90 dB minimum.
C. THD computed by FFT to 5th harmonic.
D. Inputs are half full scale less 0.5 dB. No channel
E. A/D sample rate = 500 kHz (414B,E,G), 4 MHz (414D,K),
The rates shown for sequential sampling are the
maximum A/D converter start rates and include MUX
sequencing and settling. For example, if four channels
of the PCI-414E were scanned, the maximum sample
rate on any one channel would be 2 µs x 4 channels =
8 µs (125 kHz per channel).
For fastest response on the analog comparator trigger,
keep the reference voltage near the trip input voltage. To
avoid overload recovery delays, do not let the trip input
(or any other analog input) exceed ±10V.
The input impedance of 10 M minimum avoids attenuation
errors from external input source resistance. For many
applications, an in-line coaxial 50
adjacent to the front connectors, is recommended to
reduce reflections and standing wave errors.
Allow 20 minutes warmup time to rated specifications for
models PC-414B,G,M,N.
A 25-pin DB-25S connector is used for the PC-414E, J,
and L.

compliance.
may be operated in “software differential” mode. Two
A/D’s are applied to the high and low legs of a single
differential input channel. The two data values are then
algebraically subtracted, either on the fly in real time or
after all samples have been stored. Channel capacity in
“software differential” is one-half the number of single-
ended channels.
This technique offers excellent bandwidth, high common
mode rejection and optional mix of single-ended and
differential channels.
