90IP Description

The 90IP (AC Powered) and 90IPB (External Battery Operated, 12V DC) Instrumentation Platforms are four slot chassis with controller that may be used as a bench-top instrument or in rack-mount systems. Each 90IP and 90IPB chassis has its own controller card and display providing both hard and soft front panel addressability along with space for up to 4 slot cards. The soft front panel allows GPIB or RS-232 communication to load pre-stored setup configurations. Each slot card has its own micro-controller to automatically configure the controller display when installing a slot card (smart SLOT Technology). Up to 32 of these multiple-channel instruments may be daisy chained and addressed from a PC interface to meet the needs of high channel count applications.

All 90IP's provide a carrier for a full range of products that will include:

  • Programmable Filters from 0.1 Hz to 300 kHz
  • Programmable Instrumentation Amplifiers
  • Bridge Conditioning
  • Arbitrary Waveform Generators

90IP Features

  • AC or External Battery (12V DC) powered models available for a broad range of applications.
  • The half-rack chassis allows for use in bench top or rack-mount applications.
  • Complete computer control through the GBIB or RS-232 interface.
  • Soft LabWindows/CVITM front panel for ease of use.
  • FDI's smartSLOT Technology to maximize system flexibility.
