Signal conditioning applications include:

• Sonar, navigation and aerospace

• Engine test and simulation

• Acoustic, vibration analysis & control

• Satellite and telecommunications

• Automatic test equipment (ATE)

Features/Benefits:

• Simultaneous access over 32 channels offers a low

cost, versatile and convenient way to provide

amplification and filtering.

• Three active read/write registers provide

programming and set-up verification.

• Interchannel crosstalk <-100 dB provides precision

performance solutions to design engineers, system

integrators and OEM's.

• Three pole Butterworth or Bessel transfer functions

with a broad range of corner frequencies to meet a

wide range of applications.

• High channel count density without sacrificing

performance maximizes chassis utilization.

Description

Frequency Devices' Model VM300PAFF comprises a

family of VMEbus amplifier/filter boards offering software

programmable differential amplifiers combined with

precision 3-pole Butterworth or Bessel linear analog filters

in a single width B-size (6U) VME form factor.

VM300PAFF boards provide simultaneous access to 32,

DC-coupled

wideband

signals

while

providing

programmable gain from -12dB to +42dB, in 6dB steps

and fixed frequency filters with corner frequencies from

>100 kHz to 300 kHz.

VM300PAFF boards may be

configured with 8, 16, or 32 channels.

The boards

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

Available options include AC coupled input and/or

differential output.
