Parameter Summary

Example

CALCulate:FUNCtion AVERageDBDBMLIMitNULL selects the math function to be used. One function is enabled at a time with NULL the default. The selected function MUST be enabled with CALC:STATe ON.

•AVERage measurements store the minimum and maximum readings from a number of measurements. The multimeter records the number of readings taken since the average function was enabled then calculates the average of all the readings. You read these values with CALC:AVER:MIN?; MAX?;

AVERage? and COUNt?.

•DB measurements are the difference between the input signal and a stored relative value, with both values converted to dBm.

•DBM operations calculate the power delivered to a resistance referenced to 1 milliwatt.

•The LIMit parameter enables pass/fail testing on the upper and lower limits you specify using the LIMit:UPPer and LIMit:LOWer commands.

•NULL measurements (also called relative measurements) provide a reading which is the difference between a stored null value and the input signal.

• See the section titled “Math Operations” beginning on page 41, for more detail on the CALCulate operations.

Set the Calculate Math Function to Make Upper and Lower Limit Tests on Each Measurement

CALC:FUNC LIM	Set calculate function to limit.
CALC:LIM:LOWer	Set the lower limit to test against.
CALC:LIM:UPPer	Set the upper limit to test against.
CALC:STATe ON	Enable the limit math operation.

:FUNCtion?

CALCulate:FUNCtion? queries the multimeter to determine the present math function. Returns AVER, DB, DBM, LIM, or NULL.
