Signal Path Compensation. Signal path compensation optimizes the
oscilloscope accuracy for the current ambient temperature. For
maximum accuracy, recompensate the signal path if the ambient
temperature changes by 5° C or more.
To compensate the signal path, disconnect any probes or cables from
the channel 1 and channel 2 input BNC connectors. Then, press the
Signal Path and OK Compensate Signal Path buttons to confirm
that you are ready to proceed. This procedure takes about one minute
to complete.
Factory Scope and Factory DMM. Service personnel use these functions
to calibrate the oscillscope and DMM internal voltage references.
Refer to your Tektronix field office or representative for assistance
with these processes.
