Chapter 5, FRONT PANEL OPERATION
Figure 5-12, Oscillator Menu
The Oscillator menu has five controls affecting the instrument's internal oscillator,
and is also used for accessing sub-menus that control oscillator frequency and
amplitude sweeps, and frequency and amplitude modulation. The relationship of
these menus to Main Menu 1 is shown in figure 5-13. Note that as with the main
menu structure, shown in figure 5-1, it is possible to return to the Main Display from
any menu by pressing the Main Display key, but this has been omitted from figure
5-13 for the sake of clarity.
Figure 5-13, Oscillator Menu Structure
Changes to the setting of the controls on the Oscillator menu can be made by using
the adjacent
keys.
OSC FREQUENCY
This control, which duplicates the Main Display OSC FREQUENCY control, allows the
instrument's internal oscillator frequency to be set to any value between 0.5 Hz and
150.000 kHz with a 1 mHz resolution. Adjustment is faster using the Keypad or
Active Cursor controls - see section 4.1.04.
