Generating the Modulation Format
Generating the Modulation Format
The modulation format can be turned on prior to or after setting your signal parameters. Perform the
following steps to turn the modulation format on:
1. Access the first menu within the modulation format.
This menu will show a softkey that has the format’s name associated with off and on. For example,
AM
Off On
. For some formats, the off/on key may appear in additional menus other than the first one.
2. Press the modulation format off/on key until On is highlighted.
Figure 3-2 shows the AM modulation format’s first menu with off as the format status, and Figure 3-3 shows
an example of the ESG display when the format is active.
The modulation format is now generated, however the carrier signal is not modulated until the
Mod On/Off
key has been set to on. Depending on the modulation format, the signal generator may require a few seconds
to build the signal. Within the digital formats, you may see a BaseBand Reconfiguring status bar
appear on the display. Once the signal is generated, an annunciator showing the name of the format will
appear on the display indicating that the modulation format is active. For digital formats, the I/Q
annunciator will appear in addition to the name of the modulation format.
