HP 35670A



Dynamic Signal Analyzer

The HP 35670A is a portable two- or four-channel dynamic signal analyzer with the versatility to be several instruments at once. Rugged and portable, it is ideal for field work, yet it has the performance and functionality required for demanding R&D applications.

Optional features optimize the instrument for troubleshooting mechanical vibration and noise problems, characterizing control systems, or general spectrum and network analysis.

 

 Features

  • 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
  • Built-in 3.5-inch floppy disk
  • Tachometer input
  • Source: Random, Burst random, Periodic chirp, Burst chirp, Pink noise, Sine, Swept-Sine, Arbitrary
  • Measurements: Linear Spectrum, Cross Spectrum, Power Spectrum, Coherence, Power, Spectral Density, Frequency Response, Time Waveform, Autocorrelation, Cross-Correlation, Histogram, PDF, CDF
