HP 35660A Dual-channel Dynamic Signal Analyzer
The HP 35660A Dynamic Signal Analyzer is an FFT-based instru-
ment that provides spectrum and network measurements in electron-
ics, mechanical test, acoustics, and other low frequency application
areas. The analyzer also offers built-in test and automation features,
traditionally available only with a computer. These features include
an internal programming language (HP 35680A Instrument BA-
SIC), a built in disc drive, limit testing and data tables. With automa-
tion built in, the HP 35660A can save you both time and money.
The HP 35660A performs spectrum analysis from 488 Allz to
1 02.4 kHz and network analysis from 244 AI Iz to 51.2 kHz. The FFT
provides 401 lines of resolution in both one- and two-channel modes.
Complete alias protection and digital zoom ensure high resolution mea-
surements with warranted accuracy. Measurements include linear spec-
trum, power spectrum, frequency response, gain/phase, group delay,
ti me history, and power spectral density. A built-in 3.5 inch disc drive,
compatible with HP Series 200/300 workstations, stores traces, tables,
states, and application programs.
Electrical Spectrum Analysis
The HP 35660A is typically 10 to 100 times faster than swept spec-
trum analyzers for equivalent measurements, and provides higher res-
olution (?44 4H7. throughout the 102.4 kHz frequency range). This
speed and resolution contribute to the quality of HP 35660A tests for
distortion, spur level, frequency drift, intermodulation, and other sig-
nal parameters. Amplitude accuracy of
t 0.5 dB and frequency accu-
racy of t 30 ppm guarantee precision in tests of such devices as
headsets, modems, telephone components, speakers, transducers, and
electrical motors.
Electrical Network Analysis
With two input channels and a built-in source, the HP 35660A can
quickly measure the response of low-frequency filters and networks.
Source signals provided are random noise, periodic chirp, and fixed
sine. Periodic chirp is useful for testing non-linear responses such as
output clipping of amplifiers. Random noise is ideal to get a linear
approximation of a non-linear network. Fixed sine lets you test re-
sponse at a specific frequency.
. 70 dB dynamic range
• f 0.5 dB amplitude accuracy
• f 0.4 dB and f 1.0 degree channel match
. Frequency accuracy of t 30 ppm
The HP 35660A is also a good choice for low-frequency transmis-
sion measurements in telecommunications and other areas. To ensure
highly accurate magnitude and phase measurements, the HP 35660A
offers
t 0.4 dB gain and f 1.0 degree input channel phase match. For
custom analysis of these measurements, the HP 35660A provides
waveform math, including conjugation, FFT, inverse FFT, square
root, and frequency domain integration and differentiation.
Machinery Vibration
The HP 35660A is an excellent fit for applications that require vi-
bration monitoring at full load. With the analyzer's built-in limit ta-
bles, users can implement vibration and health monitoring of engines,
machine tools, and other equipment, without an external computer
and without programming. The analyzer's internal disc drive makes it
easy to record, store, and recall limits for production or maintenance
testing.
