Math Functions
In addition to providing separate null measurement per function
capability, the multimeter provides four additional math functions: dB
measurements (
dB ), dBm measurements ( dBm ), statistics for multiple
readings ( STATS ) and limit testing ( LIMITS ). Only one of these four functions
can be enabled at a time (in addition to null measurement), and remains
in effect until you turn it off or change it.
• Front Panel Operation: To enable or change an enabled math function,
press to display MATH . Press or as needed to
select the desired math function ( OFF , dB , dBm , STATS or LIMITS ), and press
. Follow the instructions in the following sections of this guide to
set parameters for dB measurements, dBm measurements or limit
testing, or to display statistics.
• Remote Interface Operation: The following command selects the math
function to be used:
CALCulate:FUNCtion {NULL > DB > DBM > AVERage > LIMit}
The following command queries the currently selected math function:
CALCulate:FUNCtion?
This query returns the currently selected function
The following command turns the
CALCulate
subsystem, and thus all
math functions, on or off:
CALCulate[:STATe] {OFF
>
ON}
The following command queries the current calculation state:
CALCulate:STATe?
This query returns a “0” (
OFF
) or a “1” (
ON
).
Refer to the Agilent 34410A/34411A Programmer’s Reference for
complete description and syntax for these commands.
