V252-ZB11 DynamicSignals 16-Channel, 8-Pole Analog Filter

The DynamicSignals / Kinetic Systems V252 Series 8-Pole Analog Filters are single-width, C-size, register-based, VXIbus modules that contains 8 or 16 channels of fixed-frequency, low-pass filtering. Each differential input signal is received by an instrumentation amplifier which provides a high common mode rejection ratio. The V252-ZA12 and -ZC12 options provide filtering at unity gain. Pre-filter gains of 1, 10, and 100 as well as post-filter gains of 0.5, 1, 2, 5, and 10 are provided on the V252-ZB12 and -ZD12 options. The selection of gain is programmable on a channel-by-channel basis.

Eight-pole, low-pass, Bessel, Butterworth, Elliptic, or Constant-delay filters may be selected for each channel. This module is capable of providing filter cutoff frequencies from 10 Hz to 100 kHz. Cutoff frequencies are established by plug-in filter headers. These headers must be ordered separately. Standard headers provide nominal cutoff frequencies from 10 Hz to 100 kHz in a 1, 2, 5, ... progression.

This filter module is also available with an optional sample/hold amplifier per channel. This option provides for simultaneous sampling of all channels by usin g the VXI trigger lines. Input and output signals appear at the V252 front panel on 68-contact High Density connectors. The differential input signals are brought in via one of these connectors, and the filtered output pairs use a second connector. The output signals are also available as four multiplexed channels on the VXI Local Bus for the V207 or V208 ADC using the Kinetic Systems MUX-bus protocol.

Calibration inputs are provided via a host ADC reference from the VXI Local Bus or from an on-board reference. The calibration signals may be selectively placed on any channel. A Calibration Register is used to select the desired channel.

The V252 supports both static and dynamic configuration. It may by accessed using A24/A16, D16 data transfers.
