Minimum Peak

Moves the selected marker to the minimum y-axis value on the current trace.

Minimum (negative) peak searches do not have to meet the peak search criteria. It

just looks for the lowest y-axis value.

If the selected marker is Off, it is turned on before the minimum search is performed.

Remote Command

:CALCulate:DDEMod:MARKer[1]|2|…|12:MINimum

Example

:CALC:DDEM:MARK2:MIN

Notes Sending this command selects the subopcoded marker

State Saved Not part of saved state

Pk-Pk Search

Finds and displays the amplitude and frequency (or time) differences between the

highest and lowest y-axis value. It places the selected marker on the minimum value

on its selected trace. And it 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.)

The rules for finding the maximum peak are exactly the same as for Peak Search,

including the use of the peak criteria rules. However, the minimum trace value is not

required to meet any criteria other than being the minimum y-axis value in the trace.

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.

Marker Delta

Pressing this control has exactly the same effect as pressing Delta in Marker Mode

on the Settings tab. The selected marker becomes a Delta Marker. If the selected
