Example 8: Profiling Pulse Signals Measurement Examples
7-22 PN: 10585-00001 Rev. P ML2437A/38A OM/PM
Using the cursors
Cursors are used to define the points at which or between which power is measured. To
take a measurement at a single point, position one cursor. To take a measurement
between two points, use both. They are depicted as vertical dashed lines. The active
cursor is depicted in two ways:
• by a triangular end cap on the end of the dotted line.
• by a hyphen against the cursor number in the display readout box (see
Components of the Profiling Screen).
By positioning the cursors, the display readout box will show the average power
measured between the two cursors.
Position the cursors approximately 10 % inside the start and finish of the pulse. This
will help to stabilize the reading.
When Profile mode is first used, both cursors sit at the extreme right hand side of the
display. To move a cursor, press [System]
> [Control].
To move the active cursor, press [<<] or [>>]. To activate the other cursor, press
[SWAP].
If you had multiple pulses displayed on the screen and wished to compare identical
timed power readings, the cursors can be linked and then moved as a pair along the
waveform. To link the cursors, press [System]
> [Control] > [-more-] > [-more-] > [LINK
CURSR].
If the cursors are now moved using [<<] or [>>], they move as a pair.
5. Displaying the Readout box
This box can be toggled on and off by pressing [System]
> [Control] > [-more-] >
[READOUT].
6. Displaying the average power in readout mode
The average power between a set of cursors is shown at the bottom of the Display
Readout box. However, to display the average power in readout mode, press [System]
>
[Setup]
> [-more-].
Press [LINK] and toggle this setting until "ON" is displayed. To return to readout
mode, press [-back-]
> [MODE]. Toggle this setting until "Readout" is shown. To display
the resulting screen, press any hard key.
