8 Frequency Scan Measurement
Marker Function
Notes If the selected marker is parked at a point near to the edge of the trace data, the span after zoom will
remain at 10% of span.
If the selected marker is parked at a point out of current display, the start/stop frequencies will be
set to Auto first to full zoom out before performing Marker Zoom. The marker will be moved to the
center of the display if it is found located at a position out of the display after full zoom out.
Dependencies This key is grayed out when the marker has reached full zoom. If the grayed out key is pressed, an
advisory message is generated. If the equivalent SCPI command is sent, this same message is
generated as part of a “–200, Execution error” warning.
Couplings The Start and Stop Frequency will be changed to accommodate the new span upon a marker zoom.
They are set to Manual as a result. To get back the Start/Stop settings prior to a signal zoom, you
can select Marker Zoom Out that turns the Start/Stop Frequency into Auto, which will automatically
pick up the start/ stop setting for ranges turned on in the Scan table.
