Custom Arb Waveform Generator

Working with Modulation Types

Differential Wideband IQ (Option 016)

The signal generator with Option 016 can use an external I/Q modulation source such as a two channel arbitrary waveform generator to generate up to 2 GHz modulation bandwidth at RF. To enable the wideband I/Q inputs:

1.Press the front panel I/Q hardkey.

2.Press I/Q Off.

3.Press I/Q Path Wide (Ext Rear Inputs).

4.Press I/Q On.

Connect the external I/Q modulation source to the signal generator’s rear panel, differential WIDEBAND I/Q INPUTS. The voltage level at the inputs is +/– 1 Vdc. Wideband IQ is available for RF above 3.2 GHz. Refer to the Data Sheet for more information.

It is possible to use the signal generator’s internal arbitrary waveform generator (ARB) as a baseband source while using the wideband inputs at RF. The internal ARB I and Q signals are available at the I and Q OUT and the I- bar and Q- bar OUT rear panel connectors. Use the following steps to set up the internal ARB as a baseband source and enable the wideband inputs.

1.Set up the internal baseband generator with the desired signal.

2.Press the Mux hardkey.

3.Press I/Q Out.

4.Press BBG1

5.Press the front panel I/Q hardkey.

6.Press I/Q Off.

7.Press I/Q Path Wide (Ext Rear Inputs).

8.Press I/Q On.

Single-Ended Wideband IQ (Option 015 - Discontinued)

The signal generator with Option 015 can use an external I/Q modulation source such as a two channel arbitrary waveform generator to generate up to 2 GHz modulation bandwidth at RF. To enable the wideband I/Q inputs:

1.Press the front panel I/Q hardkey.

2.Press I/Q Off.

3.Press I/Q Path Wide (Ext Rear Inputs).

4.Press I/Q On.

Connect the external I/Q modulation source to the signal generator’s rear panel WIDEBAND I INPUT and WIDEBAND Q INPUT. The voltage level at the inputs is +/– 1 Vdc. Wideband IQ is available for RF above 3.2 GHz. Refer to the Data Sheet for more information.

It is possible to use the signal generator’s internal arbitrary waveform generator (ARB) as a baseband source while using the wideband inputs at RF. The internal ARB I and Q signals are available at the I and Q OUT and the I- bar and Q- bar OUT rear panel connectors. Use the following steps to setup
