Using CONFigure with a Math Operation

Using CONFigure with a Math Operation

The following example uses CONFigure with the dBm math operation. The CONFigure command gives you a little more programming flexibility than the MEASure? command. This allows you to “incrementally” change the multimeter’s configuration. The example is shown in BASIC and QuickBASIC (see next page).
