Model VM16FFFA
Fixed Frequency Filter with
Selectable Gain VME Board
16-Channel
Description
Frequency Devices' Model VM16FFFA comprises a
family of VMEbus filter/amplifier boards offering
sixteen channels of linear analog filtering with jumper-
select gain of 1, 10, 100, 200 and 500 in a single width
B-size (6U) VME form factor. Each instrument offers
sixteen differential signal inputs through a shielded
front panel connector that provides signal buffering,
gain setting, and fixed frequency filtering for each
channel. VM16FFFA boards may be configured with
one of several filters with standard factory set cut-off
frequencies from 0.02 Hz to 100 kHz, and with high- or
low-pass transfer functions allowing user to externally
cascade filters into band-pass configurations. The
boards use the VMEbus for power only.
Features/Benefits:
• A convenient way to provide simultaneous access
to 16 channels of precise filtering and gain in a VME
system.
• Individual I/O offset adjustment for each channel
allows for offset adjustment independent of gain.
• Broad range of transfer characteristics and corner
frequencies are offered to meet a wide range of
applications.
• Low harmonic distortion and wide signal-to-noise
ratio to 16-bit resolution with interchannel crosstalk
<-80 dB.
