Viewing Setup Parameters
Pressing a front-panel key which accepts data entry (such as the [Freq] or [Amptd] key)
displays the current value of a setup parameter. Table 1-3 lists the front-panel keys which
accept data entries. Pressing one of these keys does not alter the current setup values.
The units of the displayed parameter are indicated by an illuminated indicator at the right of
the display. The indicators at the left of the display indicate whether the display value is
associated with the Main Signal or the Modulation Source.
