Using signal analyzer as down converter with scope and VSA software

Keywords:oscilloscope? VSA software? signal analyzer?

Many applications in digital communications and radar need demodulation and analysis of wideband signals in the microwave region. Some of these applications can be handled by using a modern wideband oscilloscope, such as the Agilent Infiniium oscilloscopes, to directly digitize the signal for analysis with the Agilent 89600 VSA software. However, many times it is more convenient and economical to use a broadband down converter or tuner to translate the desired microwave signal down to an intermediate or IF frequency prior to digitization with an oscilloscope.

This paper will discuss using the Agilent PXA signal analyzer as a microwave down converter for an Infiniium oscilloscope or Acqiris digitizer running the 89600 VSA software. This method provides the user with the advantages of both a signal/spectrum analyzer and high-resolution vector signal analyzer, as well as a wideband system to address wideband demodulation requirements.
