    • Description:
    • ATTEN AT7328 Two-channel Analog Oscilloscope / 20M Analog Dual trace Oscilloscope    
    High brightness and high acceleration voltage of the CRT, the CRT speed, high brightness. Acceleration voltage of 2 kV, even in the case of high-speed scanning can show a clear trajectory. Alternate triggering can observe two different frequencies of the signal waveform. TV signal synchronization, the oscilloscope has a sync signal separation circuit can be maintained with the television signals and line signals field synchronization. CH1 output on the
