950H8B 数据手册
Model 950 Single ChannelDescription 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 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 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 1 Certified Tunable Filter Instruments Available Low-Pass Models: . . . . . . . . . . . . .
