The GX2475 provides two differential inputs providing the ability to make low level measurements in the presence of common mode or noisy signals. The inputs can also be configured for single-ended operation. Each channel supports AC or DC coupling. Each channel can also add an offset to the input signal, providing the ability to maximize the A to D's dynamic range.
Both channels offer three, 3-pole, low pass, butterworth filters offering the ability to band limit signal noise and minimize aliasing effects. The filters and also be bypassed to take advantage of the input amplifier's full bandwidth.
Clocking of the digitizer is provided by an external input or an internal 10 MHz, 50 MHz or 70 MHz clock which can be divided by 1 to 256. Each channel can be independently triggered to start a measurement from an external or internal source.
