Custom Arb Waveform Generator
Working with Modulation Types
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.

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
