a. Exceeding the specified input power level will cause waveform distortion.
b. Referenced to average power monitor.
c. It is recommended that a user vertical calibration be performed after every 10 hours of continuous use or if the temperature has changed
by greater than 2

C from the previous vertical calibration.
d. Where
∆

cal
represents the temperature change in Celsius from the last user vertical calibration. Note that the temperature term goes to
zero upon execution of a vertical calibration.
e. Where
∆
Time
cal
represents the time since the last user vertical calibration. The uncertainty due to time typically stabilizes after 24 hours.
This term goes to zero upon execution of a vertical calibration.
