PXI-4496 voltage range

[ap8888]

Can I increase the voltage range of individual channels on the PXI-4496? I'm guessing not, but I'm hesitatiting applying large attenuations to my signal (a factor of 4 is likely) with the fear of losing significant accuracy.

Currently I have single IEPE sensors going to individual channels, but I'm looking to sum several IEPE signals. This means that the incoming voltage will be multiplied (by the number of summed channels), so I'll need more than +/- 10V or will need to attenuate the signal.

Thanks

ap8888,

Unfortunately, the input range for this device is +/- 10V, and that cannot be increased. Rather than summing the channels prior to input, have you considered summing them (or performing other operations as needed) in software AFTER it has been inputted? This way, you wouldn't have to worry about attenuating the signal prior to input of the 4496.
