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 tie. Use
DePfx~
S&V&
, 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
SW&
ASCII .
Savs
Data uses 6 bytes per point, as opposed to about 20 bytes per point for
Save
&KII
. However, the file type is binary, and contains a header, making it difficult to read.
Querying
Marker
Searches
The analyzer can measure a filter and compute its center frequency,
bandwidth, Q, and Loss. You can query this information using the SCPI
command
CALC:MARK:F'UNC:RES?
For example:
10 OUTPUT
ORfna;"CALC:MARK:BWID
-3"
!
-3
dB
bandwidth
20 OUTPUT
ORfna;"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.
