Leader Electronics Corp. LBO-522 - Introduction; Specifications

1. INTRODUCTION
The LBO-522-LBO-523 Oscilloscopes are portable
ones with the functions of 5 mV/div. (20[35]
MHz), 500 /iV/div. {5 MHz), maximum sweep ratio
40[20] ns/div. (MAG x 5[10]), equipped with a
6-inch rectangular [metal-back] CRT with high
brightness, internal graticule and the vertical
sensitivity magnifier.
The LBO-522, 523 have a wide range of appli¬
cation in production and service areas for measure¬
ments and testings of TV set, VTRs and computer
peripheral equipments, since the TV synchro¬
nization separator, variable hold off and V-AXIS
magnifier functions are provided.
