Description

Frequency Devices model VM32FF comprises a

family of VMEbus filter boards offering 32 channels of

fixed frequency, linear analog filtering in a single width

B-sized (6U) form factor. VM32FF boards receive up

to 32 high level differential signal inputs through a

shielded front panel connector and provide signal

buffering and unity gain for each channel (optional -

customer specified gain). Boards may be configured

with 2-pole D72 or 4-pole D74 filters from 1.0 Hz to

100.0 kHz, and with high-pass or low-pass (anti-alias)

transfer functions allowing user to externally cascade

filters into band-pass configurations. Each channel

provides low harmonic distortion and wide signal-to-

noise ratio to 12 bit resolution.

Features/Benefits:

• Simultaneous access over 32 channels offers a

low cost, versatile and convenient way to provide

amplification and filtering.

• Interchannel crosstalk <-80 dB provides precision

performance solutions to design engineers,

system integrators and OEM's.

• 2- and 4-pole Butterworth or Bessel transfer

functions with a broad range of corner frequencies

are offered to meet a wide range of applications.

• High channel count density without sacrificing

performance maximizes chassis utilization.

Signal conditioning applications include:

• Industrial process control

• Engine test and simulation

• Acoustic, vibration analysis & control

• Satellite and telecommunications

• Automatic test equipment (ATE)

• Aerospace, navigation & sonar

• Automotive test cells
