2) [Sweep Setup] dialog box
a) [Channel] box
Select the channel applicable to sweep setting.
b) [Stepped Sweep] check box
In the step sweep mode, the source is tuned to a frequency point and the frequency point is measured after the
specified dwell time. Then the source is tuned to next frequency point. A device of long electrical delay can be
accurately measured. If this check box is cleared, the analyzer may work in the
analog sweep or step sweep mode,
depending on the setting of the sweep time and intermediate frequency bandwidth.
c) [Dwell time] input box
Set the dwell time at each point before obtaining the measurement data. This is only applicable to the step sweep
mode.
d) [Sweep Delay] input box
Set the waiting time of the analyzer before obtaining the measurement data. It refers to the delay before
measurement of the first point.
e) [Fast Sweep] check box
If the [Fast Sweep] check box is selected, analog sweep will be started. Data are collected in the sweep process,
thus reducing the waiting time of sweep.
4.6 Trigger Mode
The trigger signal is used to enable measurement sweep of the analyzer. The sweep mode and time to stop sweep
and return to the holding state are determined by trigger settings. The vector network analyzer has high flexibility
in trigger setting.
