4.1 Basic operation

Operation of the broadband VSA is substantially the same as that of the 89600 VSA. See the following sections for some differences or special configurations. There is an online Tutorial and Getting Started Guide under the Help/Roadmap toolbar in the 89600 software.

4.2 Sampling modes: full rate and user rate

Full rate mode

When the Sample Mode is set to full rate using the Utilities/Hardware/ADC1 /Agilent Acqiris One Channel Digitizer/Configure/Sample Mode/Edit menu path for the U1065A-001 or Utilities/Hardware/ADC1 /Agilent Acqiris Two Channel Digitizer/Configure/Sample Mode/Edit menu path for all the other models, the digitizer sample rate is fixed at the maximum for each digitizer model according to Table 4.

With the addition of the anti-alias lowpass filter described above, this mode is free of alias exposure zones. This means that no signal anywhere in the range of the VSA’s center frequency will alias upon the desired signal and corrupt the measurement.

There is a trade-off when using this mode. Although the digitizers have deep memories allowing long record lengths, if a longer Main Time (or Result Length for digital demodulation) is needed for more resolution in the frequency domain a different sample mode may be required. Go to the Configure menu, click on Sample Mode/Edit and select User Rate from the drop-down menu. The Main Time limit for any sample rate is shown in the operating region curves that appear in Appendix C.

NOTE: Any limitation to Main Time (or Result Length) will be indicated by the inability of the software to increase the Main Time or decrease RBW when Number of Frequency Points is increased.
