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.
