Working with SCXI-1143

[NAUSHICA]

Hi,

I am working with multiple signals which have peak to peak voltages of 30 to 50V.

I want to filter out the noise above 20Hz for these signals.

I saw SCXI-1143 as a possible candidate. but voltage spec is low (max input is 5V)
Is there any attenuator module for this programmable LPF module.

Regards

I want to know whether the SCXI configuration below will work or not.
Can some one help me on this.

The High Voltage signal (50Vac) will collected by an SCXI-1125 with a terminal module of SCXI-1313.
Output from back plane will go to SCXI-1143.

The filtered out put is acquired by PXI-6289 via a SCXI-1349 Adapter /SHC68 -68EPM  cable.

(All these modules should work in Parallel Mode but not a must)

Hi Naushica,

You should be fine with that configuration the SCXI-1313 has a programable 100:1 attenuator so you will be able to acquire signals +-300V. There is a filter on the SCXI-1125 but it is limited to either 4Hz or 10KHz (or off).
