Appendix A: Specifications
This section provides a complete description of the video measurement set specifications.
a description of the required temperature range and other
pertinent operating conditions.
Terms Used in Specifications
Characteristic — A characteristic refers to a property of the product.
Performance Requirement [REQ] — Performance Requirements
define characteristics that are essential to the intended application of
the product, usually in limit form.
Reference Information [RI] — Reference Information explains the
performance requirements or stipulates conditions under which the
performance requirements are effective. Reference information is not
considered to be a statement of guaranteed performance.
Refer to the Performance Conditions for
Specification — A specification is a document or a section of a
document that lists and describes characteristics and performance
requirements of a product. A specification also may contain
reference information.
Typical — Typical refers to instrument performance that can be
expected but is not guaranteed.
Performance Conditions
The Performance Requirements listed in the Electrical Specifications
apply over an ambient temperature range of 0° C to +50° C. The
rated accuracies are valid over the entire 0° C to 50° C range and
become “typical” for temperatures from –10° C to 0° C. Test
equipment used to verify Performance Requirements must be
calibrated and working within the specified limits.
All specifications (with the exception of Signal-to-Noise Ratio
Measurement Accuracy) apply for Signal-to-Noise Ratio ≥ 52 dB
(weighted). Averaging (AVG) is enabled for all specifications.
