7.6 Marker Function
7-76
{
MAX
-MIN
}
: Calculates the difference between the maximum of local
maximum peak values and the minimum of local
minimum peak values.
Moves the active marker to the position of the maximum
of local maximum peak values and moves the delta
marker (other than FIXED MKR) to the position of the
minimum of local minimum peak values.
When FORMAT is SMITH/POLAR, the internal
LOGMAG data is searched.
{MAX - MIN}
: Searches for the difference between the maximum and
the minimum.
{
X}
: Specifies the detecting sensitivity for the ripple search.
The differential coefficient X is specified here.
Specify a ratio, regarding the full scale of the horizontal
axis as 100%.
X is specified only with the ten-key.
{
Y}
: Specifies the detecting sensitivity for the ripple search.
The differential coefficient
∆
Y is specified here.
Y are specified only with the ten-key.
How to obtain ripple (local maximum peak value)
To obtain ripple value under the detecting sensitivity Y/ X, search for a point (a)
where the gradient (Y/X) of the trace is larger than Y/ X.
Next, search a point (d) where the reverse gradient (Y/X) of the trace is larger than
∆
Y/
∆
X. Then the maximum value between (a) and (d) is obtained as a local maximum
peak value.
A local minimum peak value can be obtained by reversing the polarity of Y/ X in the
above procedure.
