Example of Setting a Marker Byte
Binary
Hex
Sets markers 1 and 3 on for a waveform point
The following example shows a marker binary file (all values in hex) for a waveform with 200 points.
Notice the first marker point, 0f, shows all four markers on for only the first waveform point.
If you create your own marker file, its name must be the same as the waveform file. If you download
I/Q data without a marker file, the signal generator automatically creates a marker file with all
points set to zero. For more information on markers, see the User's Guide.
NOTE
Downloading marker data using a file name that currently resides on the signal generator
overwrites the existing marker file without affecting the I/Q (waveform) file. However,
downloading just the I/Q data with the same file name as an existing I/Q file also overwrites
the existing marker file setting all bits to zero.
