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.

The instrument exhibits an input impedance of 1 M W 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 M W 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 ConnectorsforSignal l/O

Compact size and manual rotary switch front panel controls make 950 instruments a popular, cost effective, easy-to-use solution for signal conditioning applications in the following areas:

• Anti-aliasing Filters
• Biomedical/Biotechnology Applications
• Data Recording/Playback
• Data Smoothing
• EKG/EEG Signal Filtering
• FDM/PCM Signal Filtering
• Medical Research
• Industrial Process Control
• Seismic Analysis
• Vibration Analysis
