Lbo-552C stereoscope
¡ö Two input signals in the same range can be adjusted with a common gain control.
Azimuth adjustments of the magnetic head in a tape recorder can be easily performed.
Close inspection can be made for L and R inputs by ¡°sliding¡± the waveforms to either side.
X-Y operation requires only one switch setting; no tedious reconnections and switching operations are needed.
The waveform to be measured automatically stays static, since the trigger sweep circuit is employed.
Parasitic oscillation of an audio amplifier can be readily observed, because the vertical axis has a wide band of 10 MHz.

The LBO-552C is a 130 mm Stereoscope specially adapted for observing waveforms in stereo circuits. It is a dual-trace type in which two waveforms, left and right signals, are displayed side by side. This feature permits instant comparison of amplitudes and phases for balance adjustments. Indispensable when checking stereo equipments, tape recorders, amplifiers, receivers in manufacturing plants and in service shops.
