Description

Frequency Devices’ Model VM8PF comprises a

family of VMEbus filter boards offering eight

channels of software programmable, precision linear

analog filtering in a single width B-size (6U) VME form

factor. VM8PF boards receive up to eight high level

differential signal inputs through a shielded front panel

connector and provide signal buffering and software

programmable filtering with unity gain for each chan-

nel. A second connector is wired in parallel with the

input connector to facilitate filter bypass. VM8PF

boards may be configured with 4- or 8-pole filters in

any one of five standard factory set tuning ranges from

1.0 Hz to 102.4 kHz, and with high- or low-pass

transfer functions allowing user to externally cascade

filters into band-pass configurations.

The boards

conform to VME revision C.1 as an A16/D16 Slave.

Features/Benefits:

• Simultaneous sampling over 8 channels provides

a low cost, versatile and convenient way to control

filtering and gain scaling.

• Solves precision performance problems of design

engineers, system integrators and OEM’s.

• 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.

Signal conditioning applications include:

• Engine test and simulation

• Automotive test cells

• Aerospace, navigation & sonar

• Laboratory R & D

• Acoustic and vibration analysis

• Satellite & Telecommunications

• Automatic test equipment (ATE)

• Industrial process control
