I have a Rigol DS1000Z, and I'm using it to sort of log data. I have a wavelength tunable laser that creates an electrical pulse (start of pulse is start of sweep, end of pulse is end of sweep), and I have an optical power meter which measures the laser power, and gives an electrical signal.
I trigger the oscilloscope off the rising edge of the pulse, and I look at the power meter output in another oscilloscope channel. I can then see the power vs wavelength measurements on the scope. Although not a huge issue, I was wondering if it's possible to tell the scope to stop getting data on the falling edge of the pulse, instead of just filling up its memory.
Is this possible?
