1. GENERAL

1.1 Description

The OD-514B, OD-515B & OD-545B are sturdy, easy to operate and exhibit high
operational reliability. This family of oscilloscopes are dual-channel oscilloscopes with
maximum sensitivity of 1 mV/DIV and maximum sweep time of 10 ns/DIV.
The most important differences between each model can be found in the following
table:
Bandwidth
Delay sweep system
Cursor readout
Additionally, the oscilloscopes offer several other features:
High intensity CRT with high acceleration voltage:
The CRT is a high beam transmission and high intensity type with a high acceleration
voltage of 2 kV for OD-514B and 12 kV for OD-515B and OD-545B. It displays clear
readable traces even at high sweep speeds.
A trigger level lock function
This circuit eliminates the procedures of the troublesome triggering adjustment not only for
displaying signals but also for that of video signals and large duty-cycle signals.
TV sync triggering:
The oscilloscope has a sync separator circuit for TV-V and TV-H signals triggering.
X-Y operation mode
In this mode horizontal deflection (X-axis) is via CH1 signal and vertical deflection (Y-axis)
is via CH2 signal.
CH1 Output:
CH1 output located on rear panel can be applied to frequency counter or other instruments.
Z-Axis Input:
Beam intensity modulation capability permits time or frequency markers to be added. Trace
blank with positive signal, TTL compatible.
