To print all the headers to this SDF file type:
SDFPRINT SINEARB.DAT
To print only the data for ‘’Normalized Variance’’ channel 2 (row 0 is channel 1, row 1 is
channel 2) type:
SDFPRINT SINEARB.DAT /D:1 /R:1
To now print this data in pure ASCII with no record headers:
SDFPRINT SINEARB.DAT /D:1 /R:1 /P:0
Discussion
The HP 3566A/67A generally puts all results from a measurement in a single file (see
example above).
The following types of records are present in an SDF file:
Name
Description
SDF_FILE_HDR Provides an index to the file.
SDF_MEAS_HDR Contains settings of measurement parameters.
SDF_DATA_HDR Information on one type of measurement result (X/Y info). One
measurement result can contain many rows (e.g. channels) of data
results.
SDF_VECTOR_HDR Information on which channels were used for each data result. There is
one SDF_VECTOR_HDR for each row (& column) of data in a
measurement result. Each SDF_VECTOR_HDR may reference up to 2
channels.
SDF_CHANNEL_HDR Contains channel-specific information for one channel used in a
measurement.
UNIQUE record Contains instrument-specific information.
SDF_SCAN_STRUCT Tells you how vectors are organized in the Y-axis Data record when the
measurement includes multiple scans of data.
SDF_SCAN_BIG Tells you how vectors are organized in the Y-axis Data record when the
measurement includes a large number of scans of data.
SDF_SCAN_VAR Information about each scan. This is for measurements that include
multiple scans of data.
