The 4mA current source for the IEPE/ICP sensor, AC or DC coupling
and gains of 1 and 10 are all individually programmable for each input.
Having developed a DC coupling
solution on the analog input, it is now possible to acquire more than 2 GHz of instantaneous bandwidth by making use of complex sampling.
In addition to the potential range of measurement magnitudes, other issues differentiating sensing methods include accuracy, linearity, drift over temperature, bandwidth, isolation, DC coupling
, size and cost.
3V with an x1 probe, and 300, 30, or 3V with an x10 probe, with AC or DC coupling
2 VDC, DC offset correction, power consumption of 500 mW (iT3011) and 625 mW (iT3018), AC and DC coupling
at both input and output, and bias current of 73 mA (iT3011) and 125 mA (iT3018).
A star configuration DBM has an inherent DC coupling
structure and may have an advantage, considering the complexity of the IF decoupling in the realization of the ring configuration.
Support for IEPE (Integrated Electronic Piezoelectric) inputs, including use of a 4 mA current source with 18 V compliance voltage for AC or DC coupling
Each amplifier can be individually configured to allow the selection of several different input ranges (from [+ or -]50 mV up to [+ or -]10 V), 50-[OMEGA] or 1-M[OMEGA] input impedance and AC or DC coupling
The PXIe-9529 provides flexible input ranges up to [+ or -]10 V or [+ or -]1 V, software-selectable AC or DC coupling
, and both differential and pseudo-differential input configuration, with up to [+ or -] 42.
