PIP



PROGRAMMABLE ”SMART” PREAMPLIFIER

Description

PIP is the programmable “smart” preamplifier. Due to the modern internal configuration, it offers extreme flexibility combined with superior signal parameters and high reliability. Included voltage monitor allows user to check the working conditions (supply voltages, detector bias voltage, first and last stage output voltage offset etc.)
  • User may also immediately:

- change the gain
- change the coupling (AC/DC)
- optimize the first stage transimpedance (in terms of input noise and overall bandwidth)
- reduce the bandwidth down to 1.5 MHz (for supressing wideband noise and convenient weak signal observation)
- manually or automatically supress the voltage offset.

  • The optimized parameters are immediately stored into the internal EEPROM memory and automatically loaded after the power is on.
  • Reset to the factory settings is always available, and following the manual, the operation and manipulation is both: easy and safe.
  • In some cases, detector biasing condition may be adjusted, however, for detector safety this function is blocked in factory by default.
  • Compact size
  • High signal-to-noise ratio
  • Dedicated for operation with 2-, 3- and 4-stage TE cooled or uncooled detectors
  • Parameters settable by the user:
    - output voltage offset
    - gain (in 40 dB range)
    - bandwidth:
    150 kHz, 1.5 MHz, 20 MHz
    1.5 MHz, 15 MHz, 200 MHz
    - coupling AC/DC
    - detector parameters (in some cases, with limitation)
  • Programmable modules and programmable controllers are interchangeable
  • Highly flexible configuration allows the user to adapt the module to variety of system parameters
  • Additional accessories available

 Electrical characteristics @ Ta = 20 °C
1) The preamplifier noise may significantly reduce the system perfomance in some situations. This happens for large capacitance detectors operating at high frequencies.
2) fo - noise measurement frequency
3) Depending on preamplifier option.
4) Measured with equivalent resistor at the input instead of the detector. It's to avoid the environmental thermal radiation's impact.
