| Model VM32PA 32 Channel Description Frequency Devices' Model VM32PA comprises a family of VMEbus amplifier boards offering software programmable differential amplifiers in a single width B-size (6U) VME form factor. VM32PA boards provide simultaneous access to 32, DC-coupled wideband signals while providing programmable gain from -12dB to +60dB, in 6dB steps for signal bandwidths from 100 Hz to 100 kHz. VM32PA 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. * Three active read/write registers provide programming and set-up verification. * Interchannel cross talk <-100 dB, phase match of 0.2 and gain accuracy of 0.1 dB at DC provides precision performance solutions to design engineers, system integrators and OEM's. * 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 GAIN AMPLIFIER PGA5-100 -12 dB to +60 dB in 6 dB steps Programmable Amplifier VME Board Ordering Information Channels 8, 16 or 32 Options A - AC Coupled D - Differential Output VM32PA-8-PGA5-100-D 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 VM32PA Specifications (@ 25C and rated Power Input) Programmable Amplifiers VME Board 1 M//22pF 15 V 10 Hz to 1.0 kHz 1.0 typ., 10 max. 5V, Output clamped to 9 V <-100dB @ 1 kHz, <-90dB @ 20 kHz 5.0mA 2mV RTI, NTE 40mV max.
