Description

Frequency Devices Model 9002 Dual Channel Filter/Amplifier Instrument represents a state-of-the-art combination of performance, utility, and economy. The instrument is fully self-contained, with a user configurable 110 or 220 VAC system power supply, a digital controller, display interface electronics, and mix and match filter cards tunable from 0.1 Hz to 102.4 kHz, (Optional 204.8 kHz). Each 9002 can be configured with two independent low-pass channels, high-pass channels or a high-pass/low-pass combination for band-pass operation. Filter transfer functions must be specified at time of order.

Designed with ease-of-use in mind, control programs share non-volatile random-access-memory (RAM) on the system controller card that allows for key pad or remote programming via the IEEE-488bus. The instrument is encased in a compact 3.5"H x 8.5"W x 17.0"D enclosure for bench-top use or can be mounted in a standard 19" half-rack slot.

Features/Benefits:

  • 0.1 Hz to 102.4 kHz Tuning Range
  • Selectable single-ended or differential input
  • Gain/phase matched channels
  • Memory storage for up to 8 set-ups per channel
  • Programmable AC/DC coupling
  • Fine resolution pre/post filter gain
  • Front/rear BNC connectors for analog I/O

Applications

  • Anti-aliasing
  • Sound measurements
