Pressing the Curve Buffer key accesses the Curve Buffer menu, described in section
5.3.24, while pressing the Previous Menu key returns control to the Oscillator Menu.

5.3.11 Amplitude Sweep Menu

When the Oscillator menu is displayed, pressing a key adjacent to the Setup
amplitude sweep item accesses the Amplitude Sweep menu, which is shown in
figure 5-15.
The Amplitude Sweep menu has eight controls affecting the instrument's internal
oscillator, and a link to the Curve Buffer menu (see section 5.3.24). Changes to the
setting of the controls can be made by using the adjacent
When an amplitude sweep is run, the internal oscillator output starts at the defined
start amplitude and is changed in discrete steps until it reaches the stop amplitude.
Steps are always of equal size, giving a linear relationship of output amplitude to
time. The controls operate as follows:-
RCU OSC AMPLITUDE or OSC AMPLITUDE
This control may be set to any value between 1 mV and 5.000 V rms. Adjustment is
faster using the Keypad or Active Cursor controls - see section 4.1.04.
START AMPLITUDE
This control defines the start amplitude for the amplitude sweep, which may be set to
any value between 0.000 V rms and 5.000V rms with a 1 mV resolution. Adjustment
is faster using the Keypad or Active Cursor controls - see section 4.1.04.
STOP AMPLITUDE
This control defines the stop amplitude for the amplitude sweep, which may be set to
any value between 0.000 V rms and 5.000V rms with a 1 mV resolution. Adjustment
