Display
The upper left portion of the window shows the calculated results of ‘Max. SHNR’,
‘Sub Harmonic’ and ‘Noise’. The plotted graph displays the raw data of the SHNR for
a particular value of “Sense Current” selected from [Select Trace].
Select Trace
Selects the sense current whose raw data is to
be plotted on the graph. When you click this
parameter, a list box will pop up which
contains a list of sense current. This sense
current list is automatically calculated and
displayed on the list box based on the
specified ‘Sense Current’ parameters of the
“Sweep Configuration Menu”.
