Measurement Status Box not visible
Graphs are flickering when using high measurement repetition rates
Keysight N7700 Photonic Application Suite, Fast Spectral Loss Engine, User's Guide
Possible Reason
Window minimized.
Window in background.
Window closed.
Window position stored in screen region that is
currently invisible.
Possible Reason
Usually the graph x and y range are adjusted
automatically when new measurement data is
available. Even slight differences in the
minimum / maximum values of the new trace
compared to the previous trace may require an
update of the axes then.
Troubleshooting
Solution
If you minimized the Measurement Status
window, it will stay that way until a user input
is required. You can get it back to front anytime
by clicking its entry in the task bar.
Unless "always on top" is checked, the
measurement status box may get behind other
windows. You can get it back to front by
clicking its entry in the task bar.
If you closed the status window, it will stay that
way until a user input is required. You can get it
back by selecting Measurement Status in the
View menu.
This could happen when working with multiple
screens or varying screen resolutions. By
selecting Reset Status Window Position in the
View menu, the measurement status box
position will be reset to the current top left
corner of the engine window.
Solution
If the graph x and y range is such that all
relevant features of the measurement are
visible and the same can be assumed for
subsequent measurements, use the Lock
X-Range and Lock Y-Range buttons. This will
freeze the x and y range, so no redraw of the
axes themselves will occur and flickering
should be reduced significantly.
