Chapter 1 Panel

Front Panel

• The product has a simple, intuitive and easy to use front panel, as shown in the following figure.

Display Screen

• 4.3 inch high resolution TFT color LCD clearly distinguishes the output status of channel 1 and channel 2, function menu and other important information through different colors. The humanized system interface makes human- computer interaction become easier and improves work efficiency.

Function Key

• Use Mode, Wave, and Utility key to set the modulation, fundamental wave selection and auxiliary function.

Numerical Keyboard

• Digit key 0-9, decimal point “.”, symbol key “+/-” are used for inputting the parameter. The left key is used to backspace and delete the previous bit of the current input.

Multifunction Knob / Arrow Key

• The multifunction knob is used for changing number (rotate clockwise to increase number) or as the arrow key, press the knob to select the function or to confirm the setup parameter. When using multifunction knob and arrow key to set the parameter, it is used to switch the digital bits or clear the previous bit or move (to left or right) cursor position.

CH1/CH2 Output Control Key

• Quickly to switch the current channel display on the screen (The highlighted CH1 info bar indicates the current channel, the parameter list displays the relevant information of CH1, so as to set the waveform parameters of channel 1.)
• If CH1 is the current channel (CH1 info bar is highlighted), press CH1 key to quickly turn on/off CH1 output, or press Utility key to pop out the bar and then press CH1 Setting soft key to set.
• When channel output is enabled, the indicator light will be illumined, the info bar will display the output mode (“Wave”, “Modulate”, “Linear” or “Logarithm”) and output signal of the output port.
• When CH1 key or CH2 key is disabled, the indicator light will be extinguished; the info bar will display “OFF” and turn off the output port.

Channel 2

• Output interface of CH2

Channel 1

• Output interface of CH1
• External Digital Modulation or Frequency Meter Interface or Sync Input Interface
• In ASK, FSK and PSK signal modulation, when the modulation source is selected externally, the modulation signal is input through the external digital modulation interface, and the corresponding output amplitude, frequency and phase are determined by the signal level of the external digital modulation interface.
• When the trigger source of the pulse string is selected to be external, a TTL pulse with specified polarity is received through the external digital modulation interface, which can start scanning or output the pulse string with specified number of cycles. When the pulse string mode is gated, the gating signal is input through the external digital modulation interface.
• When using the frequency meter function, the signal (compatible with TTL level) is input through this interface. It is also possible to output the trigger signal to the pulse string (when the trigger source is selected external, the trigger output option is hidden in the parameter list, because the external digital modulation interface cannot be used for input and output at the same time).

Menu Operating Soft Key
