Introduction
The VM32PAFF VMEbus family of amplifier/filter boards from Frequency Devices Inc. offer up to thirty-two
channels of software programmable differential input amplifiers combined with precision 3-pole fixed
frequency Butterworth or Bessel linear analog filters on each channel. The boards are available in a single
width B-size (6U) VME form factor and fully conform to VME Revision C.1 as an A16/D16 Slave.
VM32PAFF’s provide simultaneous access to DC-coupled wideband signals. The boards receive up to
thirty-two differential signal inputs through two shielded front panel connectors and provide signal buffering,
software programmable gain from -12dB to +60dB in 6dB steps, and fixed frequency 3-pole low pass
filtering for each channel. The boards may be configured with Butterworth or Bessel filters with cutoff
frequencies from 100 Hz to 100 kHz. Available options include AC coupled input and/or differential output.
Features/Benefits
•
Simultaneous access over 32 channels offers a low cost, versatile and convenient way to provide
amplification and filtering.
•
Interchannel crosstalk <-90 dB provides precision per-formance solutions to design engineers, system inte-
grators and OEM’s.
•
3-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.
