To Set Trigger/Output
As shown in Figure 1-21, there are two buttons on the right side of the operation panel, which are used to set Trigger and Output Control. The instruction below will help you to be familiar with these functions.
Figure 1-21
Trigger/ Output Button
1.Press Trig/Run Button, choose internal/ external or manual Trigger (Manual Trigger can only be used in Sweep and N-Cycle Burst)
The default setting for Trigger is “Internal”. In this mode, when the Sweep or Burst Mode is also selected, the Generator will continuously generate burst. At this time, press Trig/Run button, the instrument will shift from the “Automatic” Trigger mode into “Manual” Trigger mode.
When the generator uses the” External” Trigger Mode, if the Sweep or the Burst Mode is selected, signal will be continuously generated. At this time, press Trig/Run button, the instrument state will not change, and it will show “The instrument has already been triggered”.
Every time you press the Trig/Run button, “Manual” Trigger will start a sweep or generate a burst. Press the button again, and the generator will be triggered again.
2. Press Output Button, activate or deactivate the output signal.
If an overload message is shown, disconnect the external equipment from the output terminals and press Output button, reactivate the output terminal.

To Set Sine Signals
In the Menu Mode, press Sine Key to call the Sine operation. The top left corner of the screen will show the name of the current waveform, see Figure 2-3. The output Sine waveform parameters are set using the Sine operation menu.
The parameters for Sine waveforms are: Frequency/ Period, Amplitude/ High Level, Offset/ Low Level. Different Sine Signals are generated by using these parameters. As is shown in Figure 2-4, select Freq in the operation menu and the frequency parameter will show in the parameter area. Users then can change the frequency by using the direction button and the knob or the keypad.

To Set the Output Frequency/Period
(1) Press Sine Æ Freq/Period Æ Freq, to set the frequency parameter.
The frequency shown on the screen is the default value when the instrument is powered or the set value beforehand. When setting the function, if the current value is valid for the new waveform, it will be used sequentially. If you want to set the period for the waveform, press Freq/Period button again, switch to the Period parameter (The current operation is displayed in inverse color).
(2) Input the desired frequency.
Use the keypad to input the parameter value directly, and press the corresponding button to select the parameter unit. Or you can use the direction button to select the digit you want to edit, and then use the knob to change its value.

Instruction:
When using the keypad to enter the digit, you can use the Left direction button to move the cursor backward and delete or change the value of the previous digit. When using the knob to input, use the direction buttons to select the digit you want to edit and rotate the knob to change its value.
