Prerequisites
The tests in this section comprise an extensive, valid confirmation of
performance and functionality when the following requirements are met:
■
The cabinet must be installed on the instrument.
■
You must have performed and passed the procedures under
Self Tests
, and
those under
Functional Tests.
(See
■
A signal-path compensation must have been done within the recommended
calibration interval and at a temperature within ±5 ºC (±9 ºF) 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 signal-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.
■
The instrument must have been last adjusted at an ambient temperature
b18 ºC (+64 ºF) and +28 ºC (+82 ºF), must have been operating for a
warm-up period of at least 20 minutes (60 minutes for the MSO/
DPO73304DX instruments if the humidity is >60%), and must be operating
at an ambient temperature as listed in the specifications. (See
on page 76.) (The warm-up requirement is usually met in the
course of meeting the Self Tests and Functional Tests prerequisites listed
above).
■
Support sensor, probe, and adapter setups to avoid stress or torque when
connected to the device under test (DUT).
Equipment required
The performance verification procedures use external, traceable signal sources to
directly check warranted characteristics. The following table lists the required
