Description

Frequency Devices' Model VM32PA2.0 comprises a family of VMEbus amplifier boards offering software programmable differential amplifiers in a single width B-size (6U) VME form factor. VM32PA2.0 boards provide simultaneous access to 32, DC-coupled wideband signals while providing programmable gain from -12dB to +36dB, in 6dB steps for signal bandwidths >100 kHz to 2.0 MHz. VM32PA2.0 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 programmable amplification.
  • Three active read/write registers provide programming and set-up verification.
  • Phase match of ±2.0° and gain accuracy of ±0.1 dB provides precision performance solutions to design engineers, system integrators and OEM's.
  • High channel count density without sacrificing performance maximizes chassis utilization.
