Example 2:
1.
Connect the main output terminals of the calibrator to the wideband voltmeter input.
2.
Set the calibrator’s main output to 1V at 1 kHz.
3.
Read the meter and record the reading. (Let us assume, for example, that the meter
reads 0.999V.)
4.
Disconnect the leads from the main output terminals, and connect the the calibrator’s
WIDEBAND connector to the wideband voltmeter input through the supplied 50Ω
terminator.
5.
Press w.
6.
Adjust the calibrator’s wideband output with the output adjustment controls for the
same reading as in step 3 (0.999V in our example). The Wideband AC Module is
now sourcing an accurate 1V, referenced to the main output of the calibrator. (This
transfers the accuracy specification of the main ac output to the Wideband AC
Module at 1V @ 1 kHz.)
7.
Press N to establish this as a new reference.
8.
Press 1 0 m H E to set the calibrator’s frequency to 10 MHz.
9.
Adjust the calibrator’s wideband output with the output adjustment controls for a
reading of 1.00V on the wideband meter.
10.
The Control Display now shows the absolute (total) error of the wideband meter to
within the uncertainty of the Wideband AC Module flatness specification.
