6.5.4.2 CALCulate:MARKer:FUNCtion:HARMonics Subsystem
The CALCulate:MARKer:FUNCtion:HARMonics subsystem contains the commands for Harmonic Dis-
tortion measurement
CALCulate<1|2>:MARKer<1...4>:FUNCtion:HARMonics[:STATe] ON | OFF
This command switches on or off the measurement of the harmonics of a carrier signal. The carrier
signal is the first harmonic. The function is independent of the marker selection, i.e. the suffix <1|2>
or <1...4> of CALCulate or MARKer is irrelevant. It is only available in the frequency domain (span >
0).
If the measurement is started in the frequency domain (span > 0), the last span will define the search
range for the first harmonic. The level for the first harmonic will also be calculated in the frequency
domain. However, the measurement can also be started in the time domain (span = 0), in which case
the center frequency and the level used will remain unchanged.
Example:
"CALC:MARK:FUNC:HARM ON"
'Switches on the measurement of harmonics.
Characteristics: *RST value: OFF
SCPI: device-specific
Mode: A-F^
CALCulate<1|2>:MARKer<1...4>:FUNCtion:HARMonics:BANDwidth[:LIST]?
This command returns the resolution bandwidth values used by the harmonic measurment. A separate
value for every harmonic frequency is automatically calculated. It is possible to query the calculated
values with this command.
The function is independent of the marker selection, i.e. the suffix <1|2> or <1 to 4> of CALCulate or
MARKer is irrelevant.
Example:
"CALC:MARK:FUNC:HARM:BAND?"
' Returns the used bandwidth values of the harmonics measurement.
Characteristics: *RST value:-
SCPI: device-specific
This command is a query and therefore has no *RST value.
CALCulate<1|2>:MARKer<1...4>:FUNCtion:HARMonics:NHARmonics 1 to 26
This command defines the number of harmonics of a carrier signal to be measured. The function is
independent of the marker selection, i.e. the suffix <1|2> or <1...4> of CALCulate or MARKer is
irrelevant.
Example:
"CALC:MARK:FUNC:HARM:NHARM 3"
'Sets the number of harmonics to be measured to 3.
Characteristics: *RST value: OFF
SCPI: device-specific
Mode: A-F
CALCulate<1|2>:MARKer<1...4>:FUNCtion:HARMonics:BANDwidth:AUTO ON | OFF
This command specifies whether the resolution bandwidth of the 2
identical to the bandwidth of the first harmonic (OFF) or to the next largest bandwidth (corresponding
to the harmonic) of the multiple of the bandwidth of the first harmonic (ON).
