Model VM2.0PAFF Programmable Amplifiers with Fixed Frequency Filters >100 kHz to 2.0 MHz VME Board 32 Channel Description Frequency Devices’ Model VM2.0PAFF comprises a family of VMEbus amplifier/filter boards offering software programmable differential amplifiers combined with precision 4-pole Butterworth or Bessel linear analog filters in a single width B-size (6U) VME form factor. VM2.0PAFF boards provide simultaneous access to 32, DC-coupled wideband signals while providing programmable gain from –12dB to +36dB in 6dB steps and fixed frequency filters with corner frequencies from >100 kHz to 2.0 MHz. VM2.0PAFF 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. 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. • Phase match of ±2.0º and gain accuracy of ±0.1dB provides precision performance solutions to design engineers, system integrators and OEM’s. • Four pole Butterworth or Bessel transfer functions with 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 and vibration analysis • Satellite and telecommunications • Laboratory R & D • Automatic test equipment (ATE) • Industrial process control Ordering Information 8, 16, or 32 Channels AMPLIFIER/FILTER OPTIONS PGAB5-2.0 -12 dB to +36 dB in 6 dB steps Butterworth 4-pole, >100 kHz to 2.0 MHz PGAL5-2.0 -12 dB to +36 dB in 6 dB steps Bessel 4-pole, >100 kHz to 2.0 MHz Optional A- AC Coupled Input VM2.0PAFF-32 – PGAL5-2.0-1.75 MHz-A -3 dB Corner Frequency e.g.>100kHz to 2.0 MHz 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 VM2.0PAFF WIdeband Programmable Gain Amplifier with Fixed Frequency Filter Specifications (@ 25°C and rated power Input) 32 CHANNEL VME SIGNAL CONDITIONING BOARD Analog Input 1.
