Model VM8PF Programmable VME Filter Board 8-Channel 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 channel. 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 LOW-PASS FILTER OPTIONS 4-pole D824 8-pole D828 HIGH-PASS FILTER OPTIONS 4-pole D824 8-pole D828 BAND-PASS FILTER OPTIONS 2-pole pair 824BP 4-pole pair 828BP BAND-REJECT (NOTCH) FILTER OPTIONS 4-pole pair 828BR Ordering Information Channels 4 or 8 Filter Type and Corner Frequency D824 or D828 VM8PF-8-D828H8E-2 1784 Chessie Lane, Ottawa, IL 61350 • Tel: 800/252-7074, 815/434-7800 • FAX: 815/434-8176 e-mail: [email protected] • Web Address: http://www.freqdev.com Model VM8PF Programmable VME Filter Board Specifications (@ 25°C and rated Power Input) 8 CHANNEL PROGRAMMABLE FILTER BOARD Analog Input 1.
