Description
This command is used to specify the dB reference level. When DB units is selected
(:VOLTage:AC: DB), ACV db measurements will be made using the specified dB reference
level.
The reference level is specified in volts and is not range dependent. For example, a dB reference
level of 1 is 1V on all ACV measurement ranges.
Programming example
10 OUTPUT 716; “:unit:volt:ac:db:ref 2; ref?”
20 ENTER 716; A$
30 PRINT A$
40 END
Line 10 Two commands in this program message; the first sets the dB reference level to 2V,
and the second queries the reference level.
Line 20 Addresses the Model 2001 to talk.
Line 30 Displays the reference level (2).
