Math Functions
In addition to providing a separate null–per–function measurement capability,
the multimeter provides four math functions: dB measurements (dB), dBm
measurements (dBm), statistics for accumulated readings (STATS), and limit
testing (LIMITS). Only one of these math functions can be enabled at a time (in
addition to the null measurement), and remains in effect until you turn it off
or change it.
• Front Panel Operation: Press
MATH Select: OFF, dB, dBm, STATS or LIMITS.
See the dB, dBm, statistics, and limit testing sections that follow.
To turn any math function off: Press
MATH > OFF
• 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/11A/L4411A Programmer’s Reference Help for
a complete description and syntax for these commands.
The null function in the CALCulate:FUNCtion command is provided only for SCPI
compatibility with the 34401A Multimeter. This null is not available from the front panel.
The use of this null is deprecated for the 34410A/11A/L4411A. Use the null-per-function
commands found in the [SENSe:] subsystem instead. See “Null Measurements” on
page 59 and the Agilent 34410A/11A/L4411A Programmer’s Reference Help for details.
