Level
Accuracy
:
Signal levels are measured after the instrument is calibrated to the 100 MHz calibrator signal . Sources of error in
signal level measurement are shown below and are worst case for 25 ° Celsius operation . The sources of errors that are
actually encountered will depend upon signal frequency , level , and measurement technique .
