Connect the positive signal of the signal source to the CH+ screw terminal. Connect the negative signal of the signal source to the CH – screw terminal. The following figures show the connections between the USB-2404-60 and both a grounded signal source and a floating signal source. Signal Source USB-2404-60 Figure 5. -
Page 12: Analog Input Circuitry
Categories. Analog input circuitry The USB-2404-60 analog input channels are floating with respect to earth ground and to each other. The incoming analog signal on each channel is conditioned, buffered, and then sampled by a 24-bit Delta-Sigma ADC. Each channel provides an independent signal path and ADC, enabling you to sample all four channels simultaneously. -
Page 13: Stopband Bandwidth
Alias-free bandwidth Any signal that appears in the alias-free bandwidth of the USB-2404-60 is not an aliased artifact of signals at a higher frequency. The alias-free bandwidth (0.453 · is defined by the ability of the filter to reject frequencies above the stopband frequency. -
