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:
Performance Specifications
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’.
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 X-Series power sensor connected to the
device-under-test)

1. Any relative power measurement of up to 5 dB will have <1% error, excluding zero set, zero drift and noise effects. With default aperture and averaging, for
power levels above –50 dBm, zero set, zero drift and noise effects can be disregarded.
2. For all USB/LAN peak and average power sensor except U2049XA, specification is valid over a range of –45 to +26 dBm, DUT Max SWR < 1.2. For
U2049XA, specification is valid over a range of–45 to +20 dBm, DUT Max SWR < 1.2. For all models, averaging set to 32, in Free Run mode. For power levels
below –45 dBm, the effect of zero drift, zero set and measurement noise have to be considered separately base on the uncertainty calculation method
shown in Appendix A.
