OD-514B, OD-515B & OD-545B

The
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 di fferences bet ween each model can be fo und in t he followi ng

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 elimin ates the procedur es of the troubles ome trigg ering adj ustment not only for
displaying signals but a lso for tha t of vide o signals an d la rge du t y-cycle signa ls.

TV sync triggering:

The oscilloscope has a sync separat o r circuit f or TV-V and TV-H signa ls tr iggerin g.

X-Y operation mode

In this mode horizont al deflection (X-a xis) is v ia CH1 signal and vertic al deflecti on (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.
