Modulation In connector.
F3: FSK
If the FSK is selected, the following menu is available:
FSK Menu
F1: ON/OFF - Selects the FSK ON or OFF operating mode.
F2: F-HI/F-LO - Defines the High and Low frequency of the FSK.
F3: RATE - Selects the rate of alternation between the low and high frequencies.
F5: EXT/INT - Selects and enables the external FSK when the unit frequency is alternating
between the low and high frequencies by an external signal applied to the Trig
In connector.
3.7 ON Key
Use these key to control the main output signal. When the output is active, an internal LED will illuminate the button.
3.8 Cursor Movement 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 or to scroll through a list. 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 it finds an
error, 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 3.12.
When the waveform generator finishes the diagnostic self-test routine, it enters the local state (LOGS) and assumes
