Performance Tests
This section contains a collection of manual procedures for checking that the
TDS7000 Series Oscilloscopes perform as warranted.
The procedures are arranged in logical groupings such as: Signal Acquisition
System Checks, Time Base System Checks, Triggering System Checks,and
Output Ports Checks. They check all the characteristics that are designated as
checked in Specifications. (The characteristics that are checked appear with a n
in Specifications).
STOP. These pr ocedures extend the confidence level provided by the basic
procedures described on page 4--5. The basic procedures should be done first,
then these procedures performed if desired.
Prerequisites
The tests in this section comprise an extensive, valid confirmation of perform-
ance and functionality when the following requirements are met:
H The cabinet must be installed on the oscilloscope.
H You must have performed and passed the procedures under Self Tests, found
on page 4--5, and those under Functional Tests, found on page 4--6.
H A s ignal-path compensation must have been done within the recommended
calibration interval and at a temperature within ±5 _C of the present
operating temperature. (If at the time you did the prerequisite Self Tests, the
temperature was within the limits just stated, consider this prerequisite met).
A s ignal-path compensation must have been done at an ambient humidity
within 25% of the current ambient humidity and after having been at that
humidity for at least 4 hours.
H The oscilloscope must have been last adjusted at an ambient temperature
between +20 _C and +30 _C, must have been operating for a warm-up
period of at least 20 minutes, and must be operating at an ambient tempera-
ture as listed in Table 1--10. (The warm-up requirement is usually met in the
course of meeting the Self Tests and Functional Tests prerequisites listed
above).
