HP 3567A PC Spectrum/Network Analyzer

A rich measurement set makes the HP 3567A excellent for mechanical test, signal characterization, control systems, rotating machinery analysis and production test where signals are below 102.4 kHz. This PC based dynamic signal analyzer is configurable from 2 to 48 channels, and uses modular HP 3565S hardware to achieve high system performance. Since the HP 3567A is a Microsoft Windows^® application, measurement results are easily shared with other Windows applications, such as spreadsheets, word processors, and the HP 35639A Data Viewer.

The HP 3567A includes a source for stimulating circuits or systems. For fast measurement processing, a powerful hardware signal processor module converts time data to frequency domain data using the latest FFT technology. The included HP 35653C source module provides internal calibration signals and sine, noise, and pulse test stimulus.

An optional HP 35659A, SCSI interface module adds high speed transient capture, analysis, and playback capability (with HP 35656B). The optional HP 35656B, programmable DAC module also adds arbitrary waveform and chirp capability. The optional HP 35658A Tachometer/Trigger module improves order analysis.

Three optional software packages enhance the already complete measurement capability with Order Analysis, Swept-Sine, and Real-Time Octave analysis.

If portability is important, the 4 slot HP 35650B mainframe and a portable PC make very a cost effective multi-channel system.
