Photo of V1250
  • 1 unit VME 6U

  • 16 differential inputs on 34-pin (2.54mm) header connector

  • 16 single-ended outputs on LEMO connectors

  • Fixed Gain: 1*

  • ±2 Vpp input range

  • ±2 V output range*

  • Bandwidth: DC to 30 MHz

  • Output noise < 480 uV RMS (with disconnected inputs and outputs terminated to 50 Ω

  • Suitable for CAEN A1442 CSP

* with no termination: output range = ± 4V, Gain = 2.

The CAEN Mod. V1250 is a 16 channel differential to single ended signal converter in a 1-unit wide VME 6U form factor. It provides differential inputs (34-pin 2.54 mm header, Zdiff = 100 Ω) and single ended outputs (coaxial LEMO, Rout = 50 Ω).
Although the V1250 is a general purpose converter, it is best suited for the conversion of signals coming from charge sensitive preamplifiers, such as the A1442 (typ. rising edge > 10 ns). The analog bandwidth is therefore set to 30 MHz in order to optimize the signal to noise ratio.
