PROFILE OPERATION MODE PROCEDURES

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 SYSTEMCONTROLmoreSCALE. 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 SYSTEMCONTROLmoreREADOUT (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 (￿ p) and time (￿ t). The value of ￿ p represents the selected cursor reading minus the other cursor reading, and ￿ t represents the time difference between the two cur- sors. If SENSORAVERAGINGbetween 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 TRIGGERMAN- 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 SYSTEMCON- TROLmoremoreLINK 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-
