Model VM300PAFF Programmable Amplifiers with Fixed Frequency Filters VME Board 32 Channel 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. 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. Signal conditioning applications include: • Sonar, navigation and aerospace • Engine test and simulation • Acoustic, vibration analysis & control • Satellite and telecommunications • Automatic test equipment (ATE) AMPLIFIER/FILTER OPTIONS PGAB5-300 PGAL5-300 -12 dB to +42 dB in 6 dB steps Butterworth 3-pole 100 Hz to 300 kHz -12 dB to +42 dB in 6 dB steps Bessel 3-pole 100 Hz to 300 kHz Ordering Information Transfer Function B - Butterworth L - Bessel Options A - AC Coupled Input D - Differential Output VM300PAFF-16-PGAB5-250kHz-D 8, 16 or 32 Channels -3dB Corner Frequency e.g. 100 Hz to 300 kHz 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 VM300PAFF Programmable Amplifiers with Fixed Frequency Filters VME Board Specifications (@ 25°C and rated Power Input) 32 CHANNEL VME SIGNAL CONDITIONING BOARD Analog Input 1.
