Adjustment Procedures
This chapter contains information you need to adjust the TDS 340A, TDS 360,
and TDS 380. There are only three types of adjustments you can perform on the
oscilloscope: the automated and semiautomated adjustments in the system
calibration menu, attenuator adjustments, and monitor adjustments.
You should do the signal path compensation adjustment after servicing your
instrument or moving your instrument to a new operating environment (±5_ C
temperature change). The other adjustment procedures may be necessary if the
instrument fails one of the Performance Tests in the previous section.
Let the instrument warm up for 20 minutes before performing any adjustments.
Adjustment Interval. These adjustments should be done once a year.
