Tektronix VX4287 32-channel differential analog/digital
Good Condition, Working, Tektronix VX4287 32-Channel Differential Analog/Digital Serial Number B020661
The VX4287 32-Channel Differential Analog/Digital Input Module is a single width, C-Size VXI module. The thirty-two differential inputs of the VX4287 Module can be configured under program control to function either as thiry-two digital inputs (Digital mode), as thirty-two comparator inputs with time-tagging (Analog mode), or as sixteen channels of each (combination Analog/Digital mode).
In either mode, all input channels have individually programmable threshold voltages and can be programmed to active high or active low logic. Two logic threshold ranges are provided: ??25 V with a worst case accuracy of 125 mV and a resolution of 12.5 mV, or ??50 V with a worst case accuracy of 200 mV and a resolution of 25 mV. Each channel may be programmed to use either range or it may be instructed to autorange, selecting the most sensitive range suitable for a specified threshold voltage. Each channel may be individually isolated under program control.
