4-CHANNEL LOW PASS FILTER WITH SIMUL SAMPLE & HOLD CARD

The DBK45 combines the features of the DBK17 (SSH) and the DBK18 (low-pass filter) cards. Each DBK45 provides 4 input channels to a LogBook or Daq device system. Each of the main 16 analog input channels can accept four DBK45s, for a maximum of 64 DBK45s and 256 analog input channels. The simultaneous sample-hold function is activated at the beginning of each channel scan and freezes all signals present on DBK45 inputs for the duration of the scan, allowing for non-skewed readings of all channels.
The DBK45 has an instrumentation amplifier for each channel, with switch-selected gains of ×1, ×10, ×100, ×200 and ×500. A socket is provided for a gain resistor for custom gain-selection instead of the 5
