The ProDAQ 3951 Filter/Synchronization Function Card is one of the ProDAQ high density cards which can be fitted into ProDAQ Motherboards. ProDAQ modules are the most versatile VXIbus modules on the market. They provide the user with the highest channel density and functionality available today.

The ProDAQ 3951 function card is a 2-channel analog filter card. It provides a set of 8-order analog filters for applications that need higher filter capabilities than those already implemented on the ProDAQ ADC and DAC function cards.

Each of the two analog channels contains a number of 8-order low pass filter stages, providing 23 different filter settings in the range of 100Hz to 150 kHz. Fifteen of these settings are fixed, covering a range of 10-150 kHz in 10 kHz steps, while the other eight are version dependent and customizable to cover the range between 100 Hz and 10 kHz. The sixteenth setting leaves the filter fully powered, but sets the gain to zero, providing an attenuation of typ. 100 dB (MUTE).

The built-in gain stage allows for gains of 2, 1, 0.1 and 0.01 and is for example suited to improve the resolution of a DAC signal filtered through this card.

The synchronization circuitry allows to generate sample clocks with a high resolution and precision for older ProDAQ function cards. The clock is synchronized to the common clock used to synchronize function cards as for example the ProDAQ 3424 24-bit ADC and ProDAQ 3808 Counter/Frequency Meter.

The ProDAQ 3951 Filter/Synchronization Function Card is supplied with VXIplug&play drivers, that can be used with all popular software packages. The driver automatically detects and initializes all the function cards installed in one of the ProDAQ motherboard modules, removing any possibility of configuration errors.

ProDAQ modules allow the user to safely and simply expand their existing hardware and software systems.
