R858

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 factoryset 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 amplitude characteristics. R858 filters operate from noncritical ±12 to ±18 Vdc power supplies, have a 10 kW (min.) input impedance, a 10 W (max.) output impedance.
