Performance Specifications
Specification definitions
There are two types of product specifications:
–– Warranted specifications are specifications which are covered by the product
warranty and apply over a range of 0 to 55 °C unless otherwise noted. Warranted
specifications include measurement uncertainty calculated with a 95% confidence
–– Characteristic specifications are specifications that are not warranted. They
describe product performance that is useful in the application of the product.
These characteristics are shown in italics.
Characteristic information is representative of the product. In many cases, it may also be
supplemental to a warranted specification. Characteristics specifications are not verified
on all units. These are several types of characteristic specifications. They can be divided
into two groups:
One group of characteristic types describes ‘attributes’ common to all products of a
given model or option. Examples of characteristics that describe ‘attributes’ are the
product weight and ’50-ohm input Type-N connector’. In these examples, product weight
is an ‘approximate’ value and a 50-ohm input is ‘nominal’. These two terms are most
widely used when describing a product’s ‘attributes’.
The second group describes ‘statistically’ the aggregate performance of the population
of products. These characteristics describe the expected behavior of the population
of products. They do not guarantee the performance of any individual product. No
measurement uncertainty value is accounted for in the specification. These specifications
are referred to as ‘typical’.
Specification definitions
The power sensor will meet its specifications when:
–– Stored for a minimum of two hours at a stable temperature within the operating
temperature range, and turned on for at least 30 minutes
–– The power sensor is within its recommended calibration period, and
–– Used in accordance to the information provided in the User’s Guide.
–– For power measurements below –60 dBm, it is recommended to turn on the power
sensor for 1.5 hours (with the U2040 X-Series power sensor connected to the
device-under-test).
