Information
                                    The major requirements In a modern Oscilloscope are
simplicity of operation, compactness, reliability and of
course a first class performance. How well these features
have been combined in this Oscilloscope becomes self evident
as soon as a signal is displayed. Direct reading controls
enable voltages below 1OmV to over 500V from DC to over
1OMHz to be measured against time scales from 1 sec. to
200nSec. - a range of 5 million to 1 .

1.1	The bug-bear of a stability control needed on many
oscilloscopes to set up the trigger condition is completely
eliminated in this model either externally or internally,
instead diode clamps lock the all solid state circuit in a
sensitive_ready state, which is completely unaffected by
input voltage changes from 170 to 265V or 85 to 132V - a
truly stable circuit.

1.2	The time base and trigger circuit also incorporates
other new techniques to ensure rock steady triggering. The
gated AUTOmatic time base produces a bright reference line
at all time base speeds - even at 1µSec/cm with no signal
present and is teamed with a wide band trigger circuit,
which is preset for optimum sensitivity. As the trigger
circuit does not contain the AUTO circuit, it is not subject
to annoying beats and jitter, which often occur when input
signal and the AUTO free run rate interact, particularly
when displaying low level pulse waveforms.

1.3	To ensure that readings of voltage or time are within
specification irrespective of variations of local power
lines, both the Amplifier and time base are compensated to
accommodate ±10% line change. Tappings on power transformer
permit larger variations to be accepted
to suit local supply conditions.
