With Prompt for Each Port disabled, "Take" acquires data for all selected ports in one
go. Otherwise sweeps are taken port by port.
For "Direct Compensation", it is also possible to save the acquired data to file. In future
measurements, you can load these files instead of repeating the data acquisition.
Figure 10-27: Measure Fixture dialog: Direct Compensation (and Prompt for Each Port)
"Direct Compensation" data files are standard trace files, containing reflection parame-
ter traces for the related port and standard:
Table 10-4: Direct Compensation data
Prompt for Each Port File Type Description
disabled csv One csv trace file per standard,
containing reflection traces for all
selected ports; see
Chap-
ter 9.4.2.2, "ASCII (*.csv) files" ,
on page 244
enabled s1p One 1-port Touchstone file per
standard and port (see
Chap-
ter 9.4.2.1, "Touchstone files" ,
on page 238)
Tip: Remote control provides additional flexibility. You can:
●
Measure the same ports repeatedly without changing the standards and attribute
the results to different channels.
●
Calculate the compensation data for different ports, using mixed Open and Short
standards.
