Automating Measurements
Saving Measurement Results
Saving the Measurement to Disk-Save Data
Similar to Save ASCII, the analyzer can also save the measurement data onto
disk as an instrument state lile. Use Def ino Save , and turn Data ON and
turn Inst State and Cal OFF
Tip
A file saved in this manner is smaller than a file saved using S2tvo AZ&Z3 .
Save Data uses 6 bytes per point, as opposed to about 20 bytes per point for
Sawe &XXI . However, the file type is binary, and contains a header, making it difficult to read.
Querying Marker Searches
The analyzer can measure a hlter and compute its center frequency,
bandwidth, Q, and Loss. You can query this information using the SCPI
command
CALC:MARK:FUNC:RES?
For example:
10 OUTPUT @Rf na; “CALC : MARK : BWID -3”
! -3 dB bandwidth
20 OUTPUT QRfna;“CALC:MARK:FUNC:RES?”
! Get result of bandwidth search
30 ENTER QRfna;Bwidth,Center,freq,q,loss
For more details, refer to the “Example Programs” chapter of the
Programmer’s Guide.
