NOTE
With a CONTINUOUS trigger such as this, there will most
likely not be specific points of interest, so the movement
of the cursors is rather arbitrary.
If modulation is applied to the signal, or its power level al-
tered, the signal should change on the display. The signal
may not be visible if it is not in the default range which
covers +20 to –50 dBm.
SCALING In the example above, if the measured power signal is not visible because the
power is too high or low, the scaling can be altered as follows:
1. Press SYSTEM|CONTROL|more|SCALE. There are now soft keys for TOP and
BOTTOM dB levels, referring to the top and bottom of the screen, and AUTO
SCALE, which will optimize the displayed graph.
2. Enter new values so that the measured power signal is visible. The TOP value
must always be higher than the BOTTOM value.
3. When finished, press another soft key or CLR to return to the display.
CURSOR READOUT To display the CURSOR READOUT box on the screen, press
SYSTEM|CONTROL|more|READOUT (see page 4-25). This is a toggle action
and will display or remove the cursor data readout box from the display.
The readout shows a digital representation of data at the two cursor positions on
the currently displayed channel, along with the differences in power (
D p) and
time (
D t). The value of D p represents the selected cursor reading minus the
other cursor reading, and
D t represents the time difference between the two cur-
sors. If SENSOR|AVERAGING|between CURSOR averaging is on, the average
reading between the cursors is displayed at the bottom of the readout.
NOTE
If continuous trigger is selected, or the display is changing
while trying to read the readout, select TRIGGER|MAN-
UAL to stop the display update.
The readouts are updated whenever the signal trace is
updated, or if the cursors are moved. It is possible to link
the movement of the cursors so they move at the same
time. This is useful if measurements need to be taken at
specific times between the cursors, as with channeled
signals.
To link the cursors, select SYSTEM|CON-
TROL|more|more|LINK CURSR. When the cursors are
linked, a line is drawn on the display connecting the two
cursors and they will move together as one. This is dis-
