Dual Channel Filter Module is suited for OEMs.

July 23, 2003

Low-pass filter module AAF-2Fe provides 2 channels of noise reduction and anti-alias filtering that is tunable to bandwidths from 0.1-200 kHz. Compatible with 8, 12, and 16-bit A/D modules and boards, product incorporates features such as differential instrumentation gain, factory set to specification from 1x-10000x; true minimal 1.5 Vm or better DC offset; and +10 V input and output range. Output impedance is less than 0.001 ohms, and common mode rejection is 90-110 dB. Read More

AAF-2, 2 to 8 channel, tunable low-pass filter features selectable frequency ranges in Butterworth, Bessel, Cauer, or Linear Phase characteristics that eliminate noise and alias errors while providing DC and Gain accuracy for 16-bit data acquisition systems. Filter channels are fully isolated from PCI bus, and are continuously tunable from 0.1Hz to 200kHz. Input and output range is up to ±l0V while gain accuracy is ±0.00ldB@lkHz. Read More
