Model VM16FFFA 16-Channel Fixed Frequency Filter with Selectable Gain VME Board Description Frequency Devices' Model VM16FFFA comprises a family of VMEbus filter/amplifier boards offering sixteen channels of linear analog filtering with jumperselect gain of 1, 10, 100, 200 and 500 in a single width B-size (6U) VME form factor. Each instrument offers sixteen differential signal inputs through a shielded front panel connector that provides signal buffering, gain setting, and fixed frequency filtering for each channel. VM16FFFA boards may be configured with one of several filters with standard factory set cut-off frequencies from 0.02 Hz to 100 kHz, and with high- or low-pass transfer functions allowing user to externally cascade filters into band-pass configurations. The boards use the VMEbus for power only. Features/Benefits: • A convenient way to provide simultaneous access to 16 channels of precise filtering and gain in a VME system. • Individual I/O offset adjustment for each channel allows for offset adjustment independent of gain. • 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 with interchannel crosstalk <-80 dB. 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 LOW-PASS FILTER OPTIONS 2-pole D72, DP72 4-pole D61, D64, DP64, D74, DP74 6-pole D66, DP66, D76, DP76 8-pole D68, DP68, D78, DP78 HIGH-PASS FILTER OPTIONS 2-pole D72 4-pole D61, D64, D74 6-pole D66, D76 8-pole D68, D78 BAND-PASS FILTER OPTIONS 2-pole pair D64BP 4-pole pair D68BP BAND-REJECT(NOTCH) FILTER OPTIONS 4-pole pair D68BR 25 Locust St, Haverhill, Massachusetts 01830 • Tel: 800/252-7074, 978/374-0761 • FAX: 978/521-1839 e-mail: [email protected] • Web Address: http://www.freqdev.com Model VM16FFFA Specifications VME Filter Board (@ 25°C and rated Power Input) 16 CHANNELS OF FIXED FREQUENCY FILTERS AND SELECTABLE GAIN Analog Input 1.
