HP 35660A dual channel Dynamic Signal FFT Analyzer with floppy disk,
HP-Basic, and GPIB! This is a very versatile test instrument for
vibration analysis, control system tuning and analysis or audio system
frequency response testing. Originally sold for 13,000$, and still
sold by Test Equity for 6,000$!
(http://www.testequity.com/products/458/). It performs realtime FFT
analysis on two channels using a dedicated DSP processor. All the
standard FFT analysis options of windowing, peak-detection,
power-spectral density analysis etc are built-in and accessible via the
front panel buttons.
The GPIB and built-in HP BASIC allows this unit to act as a standalone
system controller in a GPIB automatic test system, running your BASIC
test program and controlling other test instruments connected to the
GPIB network cables.
Floppy disk works fine, and example BASIC program disks are included
(NOTE the disk format is HP, not Microsoft, and cannot be read on a PC
directly).
Unit passes built-in self tests (see screen shot).
Note: screen has a protective coating on it, and there is an approx 2mm
spot that is peeled off in one area, that does not affect legibility at
all, and is hard to notice unless you look closely. (see attached
photo)
Included:
HP 35660A
2 system manuals and example BASIC program disks
(no probes or GPIB cables included)
Specs:
488 ľHz to 102 kHz range in 1-channel mode
244 ľHz to 51.2 kHz in 2-channel mode
70 dB dynamic range
Built-in sine, random and chirp sources
3.5" floppy drive
