Marker
The marker functions are controlled by the arrow keys when the instrument is in
sweep mode. By pressing the left or right arrow the marker line moves across the
screen. When the key is held pressed, a mini cursor will be seen moving across
the screen and when the key is released, the marker will appear in the new posi-
tion. The marker will display the frequency and the measured value of the marker
position on the bottom line. If you press the “ENTER” key, the marker position
will move to the center of the screen and adjust the frequency span symmetrical
on both side of the new center fre- quency.
When “HOLD” is pressed, the sweep position indicator stops at the current posi-
tion and freezes the screen. In “HOLD” mode the frequency sweep is stopped and
depending on the setting of Oscillator, the RF is either On or Off. (see menus)
The “COPY” key will write the screen contents to the USB Memory stick or to the
USB Serial Device. The “COPY” function will create a Directory with the date as
directory name YYYYMMDD e.g. 20080826. In the directory the screen files are
written as .BMP with the time stamp as file name HHMMSS e.g. 164852.BMP .
During write to USB the busy icon is on, when busy goes off, it is safe to remove
the USB device.
