Marker function:
Press the
Marker
button on the front panel,
use the current marker to set the excitation in
the
Marker Function
submenu. Use the currently selected marker to achieve the following
functions:
⚫
Marker → Start
:
Set the current marker position (X coordinate) as the sweeping starting point.
⚫
Marker → Stop:
Set the current marker position (X coordinate) as the sweeping ending point.
⚫
Marker → Center:
Set the current marker position (X coordinate) as the sweeping center point. Note:
When using this command, the sweeping boundary value far from the current marker
will be changed to reduce the sweeping range, so that the marker position becomes
the new sweeping center point.
⚫
Marker → Span:
This function is only available when the current marker is a difference (delta) marker.
Set the sweeping range between the current marker position and the reference
marker position (x coordinate).
⚫
Marker → Ref Level:
Set the response value (Y coordinate) of the current marker to the reference level of
the current trace.
⚫
Marker → Delay:
Referring to the phase slope of the current marker position, the line length is adjusted
to the receiver input, this function helps to smooth the phase trace around the current
marker. For the equipment without constant group delay in the measurement
frequency span, another electrical delay adjustment is needed. This function can be
used to measure electrical length or deviation from a linear phase. This function
requires the measured phase difference, so it is only suitable for proportional
measurements.
⚫
Marker → CW Freq:
Set the current marker position (frequency) to continuous wave (CW) frequency. This
function requires the x-axis field of the current marker, otherwise, it is invalid. After
changing CW frequency with this command, enable power or CW sweeping to apply
the changed CW frequency setting.
⚫
Marker → SA:
If the current mode is SA, the center frequency is set to the current marker value; If it
is not SA mode, then switch to SA mode, set the center frequency to the current
marker value, and set span to 10 times of the previous step freq.
