The Advance OS3SOO is a general purpose 60MHz dual trace oscilloscope. Its high sensitivity and fast sweep speed make it suitable for a wide range of laboratory or production applications in both the analogue and digital fields. It has a full dual timebase with comprehensive independent triggering facilities for each. These, with a variable hold-off capability, make it particularly suitable for the examination of complex waveforms. The display modes include alternate A and B timebase sweeps and a trigger view facility allows the external or internal trigger input signal to be displayed as a third trace on the screen. The bright 8 x 10cm display with illuminated internal graticule allows the display of fast transients. The front panel controls are grouped for ease of operation and the construction and weight make it a readily portable instrument. The Digital Measurement option extends the capabilities of the instrument to provide direct digital readout of voltage, time or equivalent frequency from the oscilloscope and it can operate independently as a digital multimeter.
