Example: AC Voltage
Test
This example performs an ACV test for a power line reference frequency of
60 Hz. Change line 80 to OUTPUT 70903;"CAL:LFR 50" for 50 Hz
operation.
NOTE
When connected to the HP E1411 multimeter, some AC Standards may
exhibit voltage variations at the start of a measurement. The WAIT 1
statement (line 160) allows settling for the AC Standard output.
