The CleverScope is available with high resolution samplers of 10, 12 and 14 bits, which eliminates the ‘jaggies’ or staircase effect commonly found in oscilloscopes using standard 8 bit samplers.
The high resolution also provides a dynamic range some 64x (or 36 dB) better than offered by 8 bit samplers. The increased range and decreased noise floor is especially useful when doing spectral analysis and when making precision analog measurements.
The scope has a bandwidth of 100 MHz and an acquisition speed of 100 MSa/s, and both realtime and equivalent-time sampling is supported. According to Logica Technologies, this combination of high resolution (14 bits) and high speed (100 Msa/s) sets a new performance benchmark for digital storage scopes.
A rich feature set
The unit is also equipped with a deep memory buffer of up to 8 Mega samples per channel, which allows the full speed of the unit to be realised, even when taking long measurements. The deep buffer can easily be scrolled and zoomed and is very useful in finding elusive anomalies in complex signals.
The full scale analog input range varies from 20 mV to 400 V, and hardware input offset voltage scaling is provided in the range -25 V to +25 V in 10 mV increments, allowing accurate measurement of small signals superimposed on large offsets.
The CleverScope is further complemented by an optional built in 10 MHz signal generator. The low distortion and sweeping capabilities of the generator makes it easy to characterise the transfer function of analog systems, such as analog amplifiers, buffers, filters and others.
A 100 Msa/s 8 channel digital logic analyser option is also available for the Cleverscope, and this can be synchronised with the analog sampler and controlled by a powerful triggering system, making it very suitable for use in mixed signal applications. Figure 2 shows the Cleverscope in action, taking analog and digital measurements of an ABS braking system.
Should more than two analog or eight digital input channels be required, multiple Cleverscope units can easily be linked together via a cable, allowing full synchronisation and common triggering.
By using a PC (or notebook) as part of its user interface, the CleverScope not only offers high resolution images with convenient keyboard and mouse control, but also makes it very easy to integrate graphs and measurements into reports and documents.
Full math and realtime spectrum analysis is provided. The following figure indicates time-based signals as well as spectral analysis taken on two channels simultaneously.
The CleverScope offers freely movable and resizable windows that include signal-, zoomed signal-, spectrum analysis and control panel views. Zoomed signals can be set to track the signal cursor. All signal views include scales and labelled division marks. Horizontal and vertical cursors values and offsets are also displayed to aid measurement and documentation.
