The trace is calculated when "Src Port" is the (physical) driving port
In the Figure 5-1 , for example, the external DLL provides a task to calculate PAE
(power added efficiency) traces. The user requests the PAE trace calculation while port
1 is the driving port.
"Task Type" and "Src Port" define the first part of the trace identifier:
Cu(P<Src Port>)<lowercase_ext_dll_name>/<Task Type> /<Additional Input>
If these selections are insufficient fo fully specify the trace, Additional Input can be pro-
vided to the respective task.
Additional Input
For some task types, the basic information in "Define Trace" can be supplemented with
"Additional Input". This string is processed by the external DLL, with DLL-specific syn-
tax and semantics. If it is malformed or inappropriate for some reason, the firmware
logs and displays the error messages that are returned by the DLL. See the docs of
your DLL for details.
In Figure 5-1 , for example, the external DLL plugin is provided with additional informa-
tion about the source and receive impedance ( recimp=50;srcimp=50 ) to calculate the
PAE trace correctly.
The "Additional Input" is the last part of the trace identifier:
Cu(P<Src Port>)<lowercase_ext_dll_name>/<Task Type>/ <Additional Input>
5.3 Format softtool
The "Format" softtool allows you to define how the measured data is presented in the
diagram area.
Access: TRACE – [FORMAT]
Measured quantities and display formats
The analyzer allows arbitrary combinations of display formats and measured quantities
(see
Chapter 5.2, "Meas softtool" , on page 234). Nevertheless, to extract useful infor-
mation from the data, it is important to select a display format which is appropriate to
the analysis of a particular measured quantity.
An extended range of formats is available for markers. To convert any point on a trace,
create a marker and select the appropriate marker format (see
"Marker Format"
on page 338). Marker and trace formats can be applied independently.
