ATTEN AT7328 Analog Oscilloscope



ATTEN AT7328 Analog Oscilloscope
AT7328 Introduction: 
• CRT with Bright high accelerated pole voltage
• This oscilloscope tube is of fast speed and high light.Votlage of accelerated pole up to 2kv, able to indicate clear traceseven under
• High-speed sweep.
• Two waveforms in different frequency can be observed via alternative trigger function.
• TV signal synchronous function
• Ch1 output
• Z-axis input
Function of bright adjustable can add frequency or time marker to oscilloscope, trace of positive signal blanking, TTLmatching.
• X-Y operation
This item can be used as an X-Y oscilloscope while setting in X-Y position, CH1 is horizontal axial and CH2 is vertical axial.
