10 Specifications and Characteristics
216 Agilent N1913/1914A EPM Series Power Meters User’s Guide
Introduction
This chapter details the N1913/1914A EPM Series power meters’
specifications and supplemental characteristics.
Specification Definitions
There are two types of product specifications:
• Warranted specifications
• Characteristic specifications
Warranted specifications
Warranted specifications are covered by the product warranty and apply
after a 30- minute warm- up. These specifications are valid over the power
meter’s operating and environmental range unless otherwise stated and
after performing a zero and calibration.
Characteristic specifications
Supplemental characteristics which are shown in italics are intended to
provide information useful in applying the power meter by giving typical,
but non- warranted performance parameters. These characteristics are
shown in italics or denoted as “typical”, “nominal”, or “approximate”.
Characteristic information is representative of the product. In many cases,
it may also be supplemental to a warranted specification. Characteristic
specifications are not verified on all power meters. The types of
characteristic specifications can be placed in two groups:
• The first group of characteristic types describes 'attributes' common to
all products of a given model or option.
Examples of characteristics that describe 'attributes' are product
weight, and 50 W input Type- N connector. In these examples, product
weight is an approximate value and a 50 W input is nominal. These
two terms are most widely used when describing a product's
'attributes'.
