Setting parameters:
Length An ASCII integer value that specifies the number of bytes in the
EMPTYTAG, i.e. defines the number of bytes from the colon : to
the end brace }
Note: If you change the content of a waveform file, change also
the {EMPTYTAG-Length} value. For example, if you add a tag
or add bytes to a tag, reduce the length by the number of newly
introduced bytes.
EmptySequence An empty sequence containing blanks only. The number of used
blanks is calculated as the difference between the hex
addresses of the {WAVEFORM} tag and the hash sign # in the
{EMPTYTAG}.
The {WAVEFORM} tag always starts at hex address #4000.
Example:
{TYPE:SMU-WV, 837236424}
{COPYRIGHT:2003 Rohde&Schwarz SMU}
{DATE:2012-07-11;14:38:01}
{SAMPLES:80000}
{CLOCK:8666666.666666666}
{VECTOR MAX:1.000000038569158}
{LEVEL OFFS:3.333553817875577e-07,0}
{MARKER LIST 1:0:1;1:0;1249:0}
{MARKER LIST 2:0:1;1:0;1249:0}
{MARKER LIST 3:0:1;1:0;1249:0}
{MARKER LIST 4:0:1;1:0;1249:0}
{EMPTYTAG-15947:# ...}
{WAVEFORM-320017:#IQIQIQ...}
The example waveform file contains 436 (0x1b4) bytes before
the # sign in the EMPTYTAG; the hex address of the # sign is
0x1b5. The {WAVEFORM} starts at 0x4000. The EMPTYTAG con-
tains 15946 blanks and has a length of (15946+1) bytes.
Usage:
Setting only
{CONTROL LENGTH: ControlLength}
(optional / recommended for marker and control lists)
The tag specifies the length of all control or marker list in ASCII format.
The control length influences the way the marker and control lists are processed, in
particular the way traces are repeated; see Figure 13-4.
