3.7 ON Key
Use these key to control the main output signal. When the output is active, an
Out On
message is displayed on the left
upper side of the LCD.
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
power-on default settings. Table 3-2 lists the factory default settings. You can program the waveform generator for
any settings you want at power on, as described earlier in section 3.6.6.
