F3: Shape - Selects the shape of the modulating waveform between Sine, Triangle, or
Square. For model 4014B, only Sine is available.
F4: External - Selects and enables the external modulation by an external signal applied to
the Modulation In connector in the rear panel.
3.7 ON Key
Use this key to control the main output signal. When the output is active, the ON key will be
lit. By default, this will be ON (enabled) from a power-up. This can be changed by changing
the Out-On Def settings from the UTILITY menu.
3.8 Cursor Keys
Use these keys to move the cursor (when visible) either left or right. They are used in
conjunction with the rotary input knob to set the step size of the rotary input knob.
3.9 Rotary Input Knob
Use this knob to increase and decrease numeric values. The cursor indicates the low-order
position of the displayed value which changes when you rotate the knob (for straight numeric
entries only). For other types of data, the whole value changes when you rotate the knob.
3.10 Power-On Settings
At power-on, the waveform generator performs a diagnostic self-test procedure to check itself
for errors. If an error is found, an error code and text will appear in the display window. Other
error codes appear when you enter an invalid front-panel setting. For more information on
error codes, see the Error Indication section.
When the waveform generator finishes the diagnostic self-test routine, it enters the local state
(LOGS) and assumes power-on default settings. Table 1 lists the factory default settings or
selected after RECALL 0.
