Definitions
Specification (spec)
The warranted performance of a calibrated instrument that has been stored for a
minimum of 2 hours within the operating temperature range of 0º C – 55º C and after
a 45-minute warm up period. All specifications include measurement uncertainty and
were created in compliance with ISO-17025 methods.
Data published in this document are specifications (spec) only where specifically
indicated.
Typical (typ)
The characteristic performance, which 80% or more of manufactured instruments will
meet. This data is not warranted, does not include measurement uncertainty, and is
valid only at room temperature (approximately 23 ºC).
Nominal (nom)
The mean or average characteristic performance, or the value of an attribute that is
determined by design such as a connector type, physical dimension, or operating speed.
This data is not warranted and is measured at room temperature (approximately 23 ºC).
Measured (meas)
An attribute measured during development for purposes of communicating the expected
performance. This data is not warranted and is measured at room temperature (ap-
proximately 23 ºC).
Accuracy
Represents the traceable accuracy of a specified parameter. Includes measurement error
and timebase error, and calibration source uncertainty.
Random measuremet errors are combined using the root-sum-square method and are
multiplied by M for the desired Confidence Level. Syatematic errors are added linearly
and include time skew errors, trigger timing errors, and timebase errors as appropriate
for each measurement type.
Confidence level
For 99% Confidence use k= 2.5 in accuracy calculations.
For 95% Confidence use k= 2.0 in accuracy calculations.
