  • Introduction:
    This Tester Oscillator is used in performing an audible inspection for Rub&Buzz generated from loudspeaker.
    This equipment works at the manual and auto sweep modes and has a high capacity to classify Rub&Buzz due to its unique low THD.
    This equipment provides the optimized environment for inspecting Rub&Buzz due to its function of sweeping out at a time all the frequency range within the bandwidth of audio frequency (10Hz~30kHz).

  • Special Feature:
    1. A system for digital control of RMS output voltage and frequency.
    2. As power amplifier is embedded, you can drive a speaker directly.
    3. If Option 003 is selected, external Power Amp can be used, enhancing power.
    4. As it has a low THD of sweep oscillator, it is suitable for testing Rub&Buzz.
    5. Auto Sweep's Start, End, Duty, Time, Digital setting method.
    6. Auto Sweep Setting Data can be saved.
    7. Data selected among 5 auto sweep data can be set to operate consecutively.
    8. Output Protector. Built-In Output Circuit & Protective Circuit.
    9. Built-in speaker polarity check function
