3 Short-Range Comms & IoT Mode
3.10 Spurious Emissions Measurement
Pk-Pk Search
Finds and displays the amplitude and frequency differences between the highest
and lowest y-axis value. It places the selected marker on the minimum value on its
selected trace, and places that marker’s reference marker on the peak of its selected
trace.
This function turns on the reference marker and sets its mode to Fixed or Normal if it
is not already on. (These markers may be on two different traces.)
If the selected marker is OFF, a Delta type marker is turned on and the peak-to-peak
search is done. If the selected marker is on, but it is not a Delta marker, then it is
changed to delta, which turns on the reference marker if needed, and then it
performs the peak-to-peak function.
Remote Command
:CALCulate:SPURious:MARKer[1]|2|…|12:PTPeak
Example
:CALC:SPUR:MARK:PTP
Notes Turns on the Marker D active function
Sending this command selects the subopcoded marker
Dependencies Pk-Pk Search is not available when Coupled Markers is ON
Couplings The selected marker becomes a Delta marker if not already in Delta mode
State Saved Not part of saved state
Marker Delta
Pressing this control has the same effect as selecting Delta in "Marker Mode" on
page 1420 on the Settings tab. The selected marker becomes a Delta marker. If the
selected marker is already a Delta marker, the reference marker is moved to the
current position of the selected marker, thus resetting the delta to zero.
The control is duplicated here to allow you to conveniently perform a peak search,
and change the marker’s control mode to Delta, without having to access two
separate menus.
3.10.7.4 Properties
The controls on this tab are used to set certain properties of the selected marker.
Marker Frequency
This is the fundamental control that you use to move a marker around on the trace.
It is the same as "Marker Frequency" on page 1418 on the Settings tab.
