Figure 5-3: Trace Definition dialog
In the VNA firmware, the following string represents the measured quantity:
Cu(P<Src Port>)<lowercase_ext_dll_name>/<Task Type>/<Additional Input>
This string is displayed in the trace info and in the "Trace Manager". You can also use it
to specify the corresponding <Result> in remote commands:
●
CALCulate<Ch>:PARameter:MEASure
●
CALCulate<Ch>:PARameter:SDEFine
Define Trace
Requests the external DLL, for which the
was called, to calcu-
late a particular trace.
●
"Task Type" selects the task that is responsible for calculating this kind of trace
●
The trace is calculated when "Src Port" is the (physical) driving port
In the
, 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,
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
, 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>
