SNA5000A Vector Network Analyzer User Manual 126
sweep completion, the trigger mode is set to Hold/Stop. Continuous/Run means that the
trigger signal starts and continuously sweeps.
To switch the trigger mode to Continuous/Run, click the Run button at the top of the
TDR toolbar. To switch the trigger mode to Single, click the Stop/Single button at the top of
the TDR toolbar.
5.6 TDR Trace Setup
Without taking the set coupling into account, the settings as follows are applied to a
single trace. Usually, the traces in the TDR option are in a time-domain coupling and marker
coupling, meaning that the correlated settings are applied to all the traces. In addition, There
is a set of default trace configurations for every DUT topology.
5.6.1 Select a Trace
In addition to clicking the trace or trace information bar on the screen, the Trace pull-
down menu at the top of the TDR toolbar has the same function.
5.6.2 Scale Management
In the TDR option, there are several automatic scale settings to use, and it is allowed to
change the scale or reference value manually.
5.6.2.1 Auto Scale
To apply the automatic scale settings, click the Auto Scale button at the top of the TDR
option and click the suitable option in the pull-down menu. Every option in the menu
represents a set of automatic scale settings.
Option X means that the horizontal axis of the current trace is set automatically. For the
traces in the time domain, the scale and reference value are calculated by the DUT length.
For the traces in the frequency domain, the horizontal axis is set to the frequency sweep
setting of the channel.
Option Y means that the vertical axis of the current trace is set automatically. The scale
and reference value are calculated by the maximum and minimum of the trace data.
Option X&Y means that the horizontal and vertical axes of the current traces are set
automatically. The method is the same as introduced above.
All Trace means that the horizontal and vertical axes of all the traces are set
automatically. The method is the same as introduced above.
5.6.2.2 Manual Scale Setup
Manual scale setting is in the Horizontal and Vertical bar of the TDR/TDT tab. There
are two sets including a scroll-wheel and a textbox, the left set is used to change the scale
values, and the right one is for the reference values. The reference position of the horizontal
axis can be changed by the or button between two scroll-wheels in the Horizontal
