Speciﬁcations

Introduction

5-2 HP EPM-442A User’s Guide

Introduction

This chapter details the power meter’s speciﬁcations and supplemental

characteristics.

Speciﬁcations describe the warranted performance 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.

Supplemental characteristics, which are shown in italics, are intended to

provide information useful in applying the power meter by giving typical,

but nonwarranted performance parameters. These characteristics are

shown in italics or denoted as “typical”, “nominal” or “approximate”.

For information on measurement uncertainty calculations, refer to

HP Application Note 64-1A, “Fundamentals of RF and Microwave Power

Measurements”, Literature Number 5965-6630.
