3.6.5.1 Common Tags
The following tags are common to all file types. For description of the dedicated tags,
see
{TYPE: magic, xxxxxxxx}
(mandatory, must be the first tag in the file)
Identifies the file as a valid R&S SMBV100B file. It must be present and must be the
first in the waveform. If a file of the same name exists on the target medium, it is over-
written.
Setting parameters:
magic Designates the file type and has the following values:
SMU-WV
A valid R&S SMBV100B waveform.
SMU-MWV
A valid R&S SMBV100B multi-segment waveform.
SMU-DL
A valid R&S SMBV100B data list.
SMU-CL
A valid R&S SMBV100B control list.
xxxxxxxx Is an ASCII-coded checksum of the data part of the
WAVEFORM
tag in the file. This value is always 0 for data lists and control
lists.
The checksum for waveforms is used for detecting transmission
errors. If the
TYPE
tag contains 0 or a non-numeric value for the
checksum, it is ignored.
It is calculated in accordance with the algorithm given bellow,
where:
start
is a pointer to the first byte after the
#
character in the
WAVEFORM
tag
length
is the number of bytes between
start
and the closing
curly bracket (excluding the latter;
length
'must be divisible by 4
without a remainder.
UINT32 checksum(void *start, UINT32 length)
