ATTEN AT-7340 Analog Oscilloscope

Features

• CRT with Bright and high accelerated pole voltage This oscilloscope tube is high speed and high luminosity.
• The alternative triggering function can observe different signal waveform in two frequencies.
• TV signal synchronous function built in
• CH1 output 50 output signal in the rear panel can drive frequency counters directly or other instruments.
• Z-axial input Function of bright adjustable can add frequency or  time marker to oscilloscope, trace of positive signal blanking, TTL matching
• 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.
