Information:
                                    The Advance OS250 Oscilloscope is a 10 MHz dual trace
instrument with a 10cm x 8cm display. It is designed
for use in general purpose laboratory work, educational
uses, TV and servicing applications.

It features two identical input channels with a maximum
sensitivity of 5mV/cm and a bandwidth of DC to 10MHz.
The two channels may be viewed separately, alternately
at fast timebase speeds, or chopped at a 250kHz rate at
low timebase speeds.

Particular attention has been paid to trigger performance,
and the system used includes a variable control with
bright line operation in the absence of a signal,
or when the trigger level is outside the range of
the input signal.

But after i replace a Diode Bridge by a new ... Read More
