Goldline's DSP30 is a portable 30-channel digital 1/3 octave analyzer which uses ANSI class-0 and ANSI class 1 triple tuned style. Filters maintain 1/4dB accuracy over an 85dB range. Comes with Windows interface and 60 non-volatile memories. A serial port plus USB adapter is supplied.

Features:

  • DSP30 microphone measurement range is 27dB to 125dB.
  • Captures full 85dB window with scales from 1/4dB to 5dB.
  • Filters exceed ANSI specs.
  • Comes with RS232 computer interface
  • Model MK8A - 600 ohm omni-directional electret condenser instrument microphone included
  • An 85dB window not limited by the display.
  • Automatic Sum; Average function to normalize readings and stabilize pink noise.
  • 60 active memories.
  • IEC Flat, A, C or User designated curves.
  • A Sum mode to sum and average response curves.
  • A Subtract mode to subtract one memory from another.
  • Keypad selectable filters: ANSI triple tuned or sharper for notching applications.
  • Scales from 1/4dB to 5dB.
  • Multiple plot function.
  • Export file function.

Specifications:

  • Measurement Range: Microphone input: 27dB to 125dB SPL, Line input: -88dBu to +14dBu (.031mV to 3.88V rms), Measurement window: 85dB
