Definitions and Conditions
Specifications represent warranted performance of a calibrated instrument that
has been stored for a minimum of 2 hours within the operating temperature range
of 0 to 55 °C, unless otherwise stated, and after a 45 minute warm-up period. The
specifications include measurement uncertainty. Data represented in this document
are specifications unless otherwise noted.
Typical (typ) describes additional product performance information that is not
covered by the product warranty. It is performance beyond specifications that 80
percent of the units exhibit with a 90 percent confidence level at room temperature
(approximately 25 °C). Typical performance does not include measurement
uncertainty.
Nominal (nom) values indicate the expect mean or average performance , or an
attribute whose performance is by design, such as the 50 ohm connector. This data
is not warranted and is measured at room temperature (approximately 25 °C).
Measured (meas) describes an attribute measured during the design phase for
purposes of communicating expected performance, such as amplitude drift vs. time.
This data is not warranted and is measured at room temperature (approximately
25 °C).
