R&S Signal Generator Waveform and List Format
xxxxxxxx
Example:
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 and '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)
{
UINT32 i, result = 0xA50F74FF;
for(i=0; i < length/4; i++)
result = result ^ ((UINT32 *)start)[i];
return(result);
}
{TYPE: SMU-WV,106656}
BB:ARB:WAV:TAG? 'TYPE'
queries the content of the TYPE tag.
Response: 'SMU-WV,106656'
this is a valid waveform.
{CLOCK: frequency}
(mandatory for waveforms)
The tag specifies the clock frequency at which the waveform has to be output, in Hz (on
multi segment waveforms this tag contains the maximal clock of all segments).
A query of ARB:CLOCk? after loading the waveform returns the value set using the
CLOCK tag. This value can subsequently be altered with the aid of the ARB:CLOCk?
command.
Example: {CLOCK: 54000000}
BB:ARB:WAV:TAG? 'CLOCK'
queries the content of the CLOCK tag.
Response: 54000000
the clock frequency is set to 54 MHz.
Usage:
Setting only
{COMMENT: string}
The tag contains a plain text ASCII string of arbitrary length. The string is not analyzed
in the R&S WinIQSIM2. It is used to describe the file. The string is allowed to contain all
printable ASCII characters except the closing curly bracket.
