VME-8-300-6M

Description

This 12-bit transient recorder card stores up to 6 seconds of data at 1 MSPS simultaneously in 8 channels.

It includes programmable timing capabilities, selectable analog gain, and anti-aliasing filtering on the inputs.

A 48 channels system is currently in use on the ECE (Electron Cyclotron Emission) diagnostic at JET-EFDA.

  • Selectable bipolar input: +/-5V, +/- 2.5 V, +/- 1.25 V, +/- 0.625 V
  • 1 MOhm Input impedance except for +/- 5 V (10 kOhm)
  • +/- 50 V input overvoltage protection
  • Anti-aliasing 3rd order Butterworth passive low-pass filter at 500 kHz.
• ADC
  • LTC1412, SAR
  • 12-bit resolution, no loss of bits
  • up to 3.0 Msample/s 
• Digital inputs 
  • External Clock, external Trigger (active on rising edge), Clock gate (synchronous), TTL levels (with pull-up)
  • Unipolar LEMO sockets 
  • Signal ringing over-voltage protected
  • Programmable trigger delay (333ns resolution)
