R858 Series

1.0 Hz to 102.4 kHz

8-Bit Programmable

2" x 4" Range Switch

8-Pole Filters

Description

The R858 Series are digitally programmable, 8-pole

low-pass and high-pass active filters that contain a

low and a high programmable frequency range, with

each range tunable over a 256:1 ratio. R858 filters

are available with any two of five standard factory-

set tuning ranges or 8-bit custom ranges from 1.0

Hz to 102.4 kHz. These units contain 8 CMOS logic

inputs that can be operated in a transparent or

latching mode and 1 logic input for range selection.

All R858 Series models are convenient, easy to

use, fully finished filters which require no external

components or adjustments. They feature low

harmonic distortion, and precision phase and ampli-

tude characteristics. R858 filters operate from non-

critical ±12 to ±18 Vdc power supplies, have a 10

kW (min.) input impedance, a 10 W (max.) output im-

pedance.

Features/Benefits:

• Low harmonic distortion and wide signal-to-noise

ratio to 16 bit resolution.

• Digitally programmable corner frequency allows

selecting cut-off frequencies specific to each

application.
