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:
· Adjustable Frequency Control
· Differential Input Amplifiers
· Adjustable Gain Control
· Off-set Adjustment
· 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
