2 Performance Test Calibration
Optional AC voltage performance verification test
These tests are not intended to be performed with every
calibration. They are provided as an aid for verifying
additional instrument specifications.
AC voltage configuration:
(CONFigure[:VOLTage]:AC [<range|MIN|MAX|AUTO>
[,resolution|MIN|MAX|DEF>]])
1 Select the AC Voltage function.
2 Select each range in the order based on the input voltage
and frequency. Compare the measurement results with the
appropriate test limits shown in the Table 2- 9. (Be
certain to allow for appropriate source settling.)
