10.3.1. sweep generator
The generator works as sinus generator logarithmic in the range of 1Hz to 10kHz. The wobble time
is adjustable between 1 and 1000s. The synchronization markers are adjustable. These markers
are exported on the trigger output by analog connectors as L/H signals.
The wobble generator has the following adjustable parameters:
grun,0,0,0
switch off the function generator
gaswe,channel,value 0 to 100% amplitude
goswe,channel,value 0 to 100% offset
gsswe,channel,value 1 to 10000Hz start frequency
geswe,channel,value 1 <= gsswe < geswe <= 10000Hz
gtswe,channel,value 1 to 1000s
gcswe,channel,value 0 to 232-2
0 = permanent
gmswe,channel,value 1 to 10000Hz start marker L/H
gnswe,channel,value 1 to 10000Hz end marker H/L
The next image shows an example for a wobble function:
