Arbitrary Waveform Generator Functions
Enable and Disable Channels
Press , , or buttons to switch the selected channel and the output state. The state of the channel is displayed with a led / on the upper part of each channel, when a channel is selected the button is highlighted with the color of that channel or , in that case the parameters of that channel can be selected and edited. If the switch is in ON mode and the channel is not selected , the channel button changes to ON mode or .
To Set Waveform output
The following section describes how to set and output one of the available waveforms: Sine, Square, Ramp, Pulse, Noise and Arbitrary.
Detailed Instructions
- Select the desired waveform from the Waveform Panel (see Table 6).
- For setting the Frequency, Amplitude, Offset and Phase, etc press the respective , , or ... button in the wave parameters submenu, then the cursor will be activated in the respective box.
- The value can be modified through the Numeric Keypad (see Table 9), or through the Universal Knob and Arrows (see Table 8). The decimal can be changed with the left/right arrows below the knob.
- The unit is selected via the Units Keypad (see Table 10).

Detailed Instructions
- To select an arbitrary waveform from an external .csv or .bin file press csv or bin button in the top menu, then a window will open to select the .csv / .bin file, then press the OK button to load the waveform in the status view. This option is only enabled if Arbitrary signal is selected.
-
To select a Predefined Arbitrary Waveform Signal, press the Predefined Waveform button, to display the window containing the predefined arbitrary function signals to be loaded into the channel view.
Table 23. Predefined Arbitrary Waveform Signal
1 Arbitrary signal function selection information. 2 The name of the selected function. 3 Graph of the selected function. 4 Table of functions of arbitrary signals. 5 Loading arbitrary waveform from extern file. 6 Loading arbitrary waveform from file. 7 Cancel button. 8 Select button that loads the currently selected signal. - The function with the Green border shows the currently selected function.
- The functions with a Blue border shows the currently available functions.
- The functions with a Red border are not yet available.
- Load Arbitrary Waveform from external File
1. Press the 'Load arbitrary waveform' button
2. Select the wave arbitrary file extension (.csv or .bin)
3. Select the file. The menu for selecting the file is displayed.
4. Press the OK button.
5. The arbitrary waveform is loaded into the menu with its parameters and graph.
- Load Arbitrary Waveform from external Source
1. Press the 'External Source' button
2. Select the wave arbitrary file source (Audio)
3. Select the file. The menu for selecting the file is displayed.
4. Press the OK button.
5. The arbitrary waveform is loaded into the menu with its parameters and graph.
Arbitrary Waveform Generator Modulation Functions
The following section describes how to set and output one of the three available modulations: AM, FM and PM.
Detailed Instructions
- For setting the AM Frequency, FM Frequency, FM Deviation, PM Frequency and PM Phase, etc press the respective ,, or … button in the modulation parameters submenu, then cursor will be activated in the respective box.
- To adjust the parameters of the carrier wave, it is done in the signal display in Generator mode. At the moment only the sine waveform is available as a carrier.
- To change the parameter of the modulation wave is done by selecting it from the table.
- The modulation index, FM deviation and carrier frequency of the FM modulation are automatically calculated if the value of one of the parameters is changed. For example:
- If the modulation index value is changed, FM DEV is calculated.
- If the value of Carr Freq or FM DEV is changed, the Mod index is calculated.

Arbitrary Waveform Generator Other Functions
The following section describes other functions of AWG like: the sweep and the burst.
To Set Sweep

|
Detailed Instructions
- Select a waveform (Sine, Square, Ramp, etc.) before applying the sweep.
- Press the Frequency button to configure the sweep with a start frequency and a stop frequency (not implemented yet).
- Press the Amplitude button to configure the sweep with a start amplitude and a stop amplitude.
- For setting the Start Frequency, Stop Frequency, Frequency Stop, Number of Steps and Sweep Time, etc press the respective ,,, or button in the sweep parameters submenu, then cursor will be activated in the respective box.
- The start frequency, frequency steps and number of steps are automatically calculated if the value of one of the parameters is changed. For example:
- If the number of steps or start frequency value is changed, frequency steps is calculated.
- If the number of steps or start frequency value is changed, frequency steps is calculated.
