Warranted Characteristics
This subsection lists the various warranted characteristics that describe the
TAS 455 and TAS 465 Analog Oscilloscopes. Included are electrical and
environmental characteristics.
Warranted characteristics are described in terms of quantifiable performance
limits which are warranted. This subsection lists only warranted
characteristics. A list of typical characteristics starts on page 1Ć17.
NOTE
In these tables, those warranted characteristics that are checked in
the Performance Verification procedure, found in Section 4, appear
in boldface type under the column Name.
The electrical characteristics found in these tables of warranted characterisĆ
tics apply under the following conditions:
H The oscilloscope has been adjusted at an ambient temperature between
+20_ C and +30_ C
H A warmĆup period of at least 20 minutes has occured
H The operating temperature is between -10_ C and +55_ C (unless
otherwise noted)
H The Temperature Compensation Calibrations (signal path compensaĆ
tion) have been performed
