The VM7004 provides four independent channels of programmable resistors. It is designed for applications such as sensor simulation, process control, and ATE calibration. Three VM7004s can be accommodated in a single C-size card slot, giving the user up to 12 independent channels in a very small footprint.
The VM7004 is part of the VMIP™ family of instruments and can be combined with up to two other modules to form a high-density VXIbus instrument that fully utilizes the capabilities of the VMIP™. For example, when combined with the VM2716A Scanning Voltmeter, current measurements can be made.
Each resistance channel has a four-wire connection which eliminates connector and wiring resistance from critical measurements, maintaining the high accuracy of the VM7004. A four-wire monitor bus is provided giving access to any one of the four resistors at a single port. This feature can be used for station calibration and self-test, allowing the test station to make a four-wire resistance measurement of the programmed value. The monitor bus can also be paralleled across a large number of VM7004s, eliminating the need to add multiplexer switching to measure the resistors.
