AMPLITUDE DRIFT

 

 

After setting a particular amplitude, it may take up to 3 minutes (typically) for the pulse 
generator circuitry to reach thermal equilibrium. The initial amplitude may be up to 
~10% less than the set amplitude until the circuitry has warmed up. For this reason, 
amplitudes should be verified by oscilloscope measurements in applications where 
accuracy important.
