| Model VM32FF 32 Channel 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-tonoise 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 LOW-PASS FILTER OPTIONS 2-pole D72, DP72 4-pole D74, DP74 HIGH-PASS FILTER OPTIONS 2-pole D72 4-pole D74 Fixed Frequency VME Filter Board 25 Locust St, Haverhill, Massachusetts 01830 * Tel: 800/252-7074, 978/374-0761 * FAX: 978/521-1839 e-mail: sales@freqdev.com * Web Address: http://www.freqdev.com Model VM32FF Specifications (@ 25C and rated Power Input) Analog Input 1.
