Wide Bandwidth Vector Signal Analysis Measurements
- 300 MHz bandwidth vector signal measurements to 50 GHz for aerospace/defense and general purpose applications
- System calibration over the 300 MHz bandwidth
300 MHz wide bandwidth vector signal analysis measurements to 50 GHz center frequency can now be realized. The combination of the Agilent PSA Series spectrum analyzer and the Agilent Infiniium oscilloscope along with the Agilent 89601A vector signal analysis software gives you the ability to make VSA measurements on signals with up to 300 MHz bandwidth. The E4440A series PSA is used as the down converter, converting input signals that range from 3.80 GHz to 50 GHz center frequency to an IF output frequency of 321.4 MHz. The IF signal is then applied to an Infiniium scope for digitization. The digitized data is then analyzed by the 89601A VSA software which could either be on a separate PC or reside in the Infiniium Oscilloscope.
Communication between the instruments and the 89601A software is accomplished using LAN and a hub or switch. If you need to tie the time bases together, use the signal generator time base as the master.
The calibration is completed at the center frequency you select on the 89601A VSA software to make your measurements. Calibration is simple. Connect the signal source to the input of the PSA Series, access the extended calibration under the utilities menu and follow the steps. The VSA software will choose the center frequency on the PSA and step the source over the 300 MHz bandwidth center about the frequency set on the VSA software.
