950L8B Datasheet, PDF (1/9 Pages) Frequency Devices, Inc. – Tunable Filter Instruments

Model 950
Single Channel- Certified
Description
Frequency Devices’ Model 950 instruments furnish
the user with an 8-pole low-pass or high-pass filter
that is tunable by front panel controls. The controls
allow the user to select a corner frequency between
10 Hz and 50 kHz with 6 steps from each of two
selectable ranges.
Tunable Filter Instruments
The instrument exhibits an input impedance of 1
Meg Ω shunted by 47pF to a single ended signal
source. When configured in the differential mode,
the instrument has a common mode rejection ratio
(CMRR) which exceeds 60dB; in this mode the
instrument presents an input impedance of 2 Meg Ω
shunted by 47pF to a double ended single source.
Front panel gain control also enables the operator
to select a gain factor of 0, 10, or 20dB.
Standard operational features include:
1) Adjustable Frequency Control
2) Differential Input Amplifiers
3) Adjustable Gain Control
4) Off-set Adjustment
5) BNC Connectors for Signal I/O
