INSTRUMENTS For Speed and Acmracy HEWLETT-PACKARD COMPANY a 9 5 C A G E MILL R O A D . C A L O A L T O . CALIFORNIA 1 R ESEARCH into the fields of electrical engineering, physics, chemistry and all phases of science is greatly aided by the use of modern electronic measuring devices. The accuracy with which measurements are made is the yardstick of progress. Time is always an important element. Thus, electronic instruments should combine speed of operation with accuracy. It was with this idea in mind that -hp- instruments were developed. In all -hp- instruments the accem is on speed combined with accuracy. Speed is obtained by simplicity of operation- accuracy by advanced design and construction. On the following pages is a comprehensive description of the -hp- instruments which are now in use by leading organizations throughout the country. Continual engineering and research in the -hp- laboratory is resulting in newer develop- ments and additional instruments to answer the increasing number of problems encountered in the field of electronic research and production. . i INDEX OF EQUIPMENT MODEL DESCRIPTION PAGE 200 Series Resistance-Tuned Audio Oscillators . . 12 A, B, C and D 205A 205AGI 1 Audio Signal Generators. . . . 14 400A Vacuum Tube Voltmeter . . 16 300A Harmonic Wave Analyzer . . . . 1s 320 Series Distortion Analyzers . . . . . 20 AandB 500A Electronic Frequency Meter . . !2 325B Noise and Distortion Analyzer . . . . 24 210A Square Wave Generator . . . . . . 26 100 Series Secondary Frequency Standards . . . . 28 A and B 350A Attenuators and Voltage Dividers . . . 30 1
