Introduction
The HP 35670A,
1
which is the successor of the HP 35665A, is a versatile
Dynamic Signal Analyzer with a built-in source for general spectrum and
network analysis and for octave, order, and correlation analysis. Rugged and
portable, it is ideal for field work, yet it has the performance and functionality
required for demanding R&D applications.
The built-in source, with optional analysis features, optimizes the instru-
ment for analyzing and troubleshooting noise, vibration, and acoustic prob-
lems, evaluating and solving rotating machinery problems, and
characterizing control systems parameters. Some of the important features
of the Agilent 35670 are the following:
•
Frequency range of 102.4 kHz at 1 channel, 51.2 kHz at 2 channel,
25.6 kHz at 4 channel
•
100, 200, 400, 800, and 1600 lines of resolution
•
90 dB dynamic range, 130 dB in swept-sine mode
•
Source: random, burst random, periodic chirp, burst chirp, pink
noise, sine, arbitrary waveform
•
Measurements: linear, cross, and power spectrum, power spectral
density, frequency response, coherence, THD, harmonic power, time
waveform, auto-correlation, cross-correlation, histogram, PDF, CDF
•
Octave analysis with triggered waterfall display
•
Tachometer input and order tracking with orbit diagram
•
Built-in 3.5-inch floppy disk drive
