Screenshot Button

Function

Takes a Screenshot of the entire screen, and saves it as .JPG- or .PNG-file.. Press the Screenshot Button and then select the JPG Button or PNG Button to specify the image file type. To save a screenshot a folder can be selected before pressing the OK button. The image is saved to the selected location and named as: AWG_Screenshot_Date-Time.jpg or AWG_Screenshot_Date-Time.png. If no folder is selected before clicking "OK," the file will be automatically saved to the current folder location.

		Returns the unit of gigabytes per second to the numeric value entered		Returns the decibel-millivolt unit to the entered numeric value.
		Returns the unit of megabytes per second to the numeric value entered.		Sets a decibel-microvolt unit if the active parameter receives amplitude values or nano-seconds unit if the active parameter corresponds to unit of time.
		Returns the unit of kilobytes per second to the numeric value entered.		Sets a unit of millivolts if the active parameter receives voltage values or unit of milliseconds if the active parameter corresponds to unit of time.
		Returns the unit of bytes per second to the numeric value entered.		Sets a unit of microvolts if the active parameter receives voltage values or unit of microseconds if the active parameter corresponds to unit of time.
		Place as a percentage unit if the active parameter is in percentage, or degrees if the active parameter is expressed in degrees.		Sets a unit of Volts if the active para- meter receives voltage values or unit of seconds if the active parameter corresponds to unit of time.

Vector Signal Generator Functions

Enable and Disable RF Channels

Press or to activate the state the specified RF channel or to change the selected channel to edit output parameters. When the button is fully colored , it means that the state for that channel is activated and the channel is selected for editing its parameters from the interface, when the button only has a colored stripe below ,it means that the state for that channel is activated, but it is not the channel selected for parameter editing at that moment, when the button is completely gray , , it means that the output for that channel is off and it is not selected for parameter editing either. The output on of the channel is activate with a led / on the upper of each channel.

Enable and Disable MOD Channels

Press or to change the selected modulation channel to edit output parameters. When the button is fully colored ,it means that the modulation channel is selected for editing its parameters from the interface, when the button only has a colored stripe below ,it means that the state for that channel is activated, but it is not the channel selected for parameter editing at that moment, when the button is completely gray , it means that the output for that channel is off and it is not selected for parameter editing either.

Press or to activate the output on the specified modulation channel (I for channel 1 and Q for the channel 2). When the toggle switch is gray or , it means that the output for that channel is activated.

Enable Constellation Map

Press and to activate the Y2 and display the constellation map. Both toggle switches must be green and to see the constellation map.

To Set RF Output

Press the RF button, to show the RF waveform parameter submenu.

Table 10. To Set RF Output

1 RF frequency parameter. 2 RF amplitude parameter.

The following section describes how to configure the RF output.

Detailed Instructions

1. For setting the Frequency or Amplitude, press the respective or , button in the wave parameters submenu, then the cursor will be activated in the respective box.
2. The value can be modified through the Numeric Keypad (see Table 20 on page 19), or through the Universal Knob and Arrows (see Table 19 on page 19). The decimal can be changed with the left/right arrows below the knob.
3. The unit is selected via the Units Keypad (see Table 21 on page 20).

To Set Single Carrier

Press the MOD1 button a then Single Carrier radio button, to activate the Single Carrier modulation waveform parameter submenu.

Table 11. To Set Single Carrier

1 Select Single Carrier modulation. 2 The radio buttons that allow to select the QAM kind for the modulation. 3 Enable gray code or Diff Coding. 4 Data source buttons to be modulated. 5 Amplitude Signal IQ parameter. 6 Symbol Rate parameter. 7 Roll-off Factor parameter. 8 Constellation map.

The following section describes how to configure the Single Carrier output.

Detailed Instructions

The conditions are shown in the following table.

There are limitations to the Symbol Rate parameter and it is subject to the following formula:

R= 250Mbps/(4*Fs )

Where R is the nearest integer approximation of the value entered by the user Fs (Symbol Rate) that will be displayed on the screen, taking into account a factor of 4 and a fixed frequency.

To Set OFDM

Press the MOD1 button an then OFDM radio button, to show the OFDM modulation waveform parameter submenu. .

Table 12. To Set OFDM

1 Select OFDM modulation. 2 The radio buttons that allow to select the QAM kind for the modulation. 3 Enable gray code or Diff Coding. 4 Data source buttons to be modulated. 5 Arrow buttons to increase or increase the value of the FFT length points. 6 Constellation map.

The following section describes how to configure the OFDM output.

Detailed Instructions

Option 5 allows to select 3 sizes FFT, as described in the table below.
