The VM7510 is a precision DC voltage standard which is designed to be used in conjunction with high-performance digitizers, such as the VM2601 family, to facilitate calibration with a test system. The VM7510 provides a precision +/- 0.5 V signal which can be used as the DC reference during calibration to provide a higher level of accuracy than typical specifications. An on-board precision switch provides the flexibility to allow users to select between the measurement input, the internal DC source, or an external AC calibration source without the need for external signal routing or cabling.
As part of VTI’s VMIP series of modular instruments, the VM7510 can be combined with up to two other measurement or stimulus functions to provide a flexible high-performance instrument in a single “C”-size VXI slot. For example, the VM7510 can be integrated with the VM2601, 80 MSa/s digitzer and VM2164, 200 MHz dual counter/timer on a VM9000 carrier, to provide a versatile, high-performance measurement system on a standard VXI module.
