Trace Display
Sets the display contents of the selected trace. By default, it is Data.
⚫ Data
⚫ Memory
⚫ Data&Memory
⚫ OFF
Remarks:
⚫ You need to perform Data->Memory operation first, and then the memory
data can be displayed.
⚫ If you do not perform Data->Memory operation, the menu items Memory
and Data&Memory under Trace Display are grayed out and disabled.
⚫ If you select "OFF", the trace is not displayed.
Data->Memory
Saves the measurement data of the selected trace to the memory. You can use the
storage trace to compare the data trace on the screen.
After performing Data->Memory operation, when you select "Memory" or
"Data&Memory" as the trace display, an additional trace called memory trace is
displayed on the screen. The measurement data trace is slightly brighter than the
memory trace, so you can distinguish them from this point.
Trace Format
Sets the display format of the selected trace.
1. Log Mag
Shows the log magnitude of the measurement results of the trace. The unit is
dB.
2. Phase Mag
Shows the phase of measurement results of the trace. The display range is from
-180° to +180°. The unit is degree (°).
3. Group Delay
Shows the group delay characteristics of the DUT. The unit is second (s).
4. Smith
A circular diagram that primarily shows impedance or reflection characteristics
of a DUT. In this format, the position of trace plotting is the same as that in Polar
