The Acquisition Unit

  • Two 10 bit analogue channels sampling simultaneously at 100 MSa/sec. AC or DC coupled.

  • Gain automatically set from 20mV full scale to 800V full scale by choosing graph view and probe switch setting.

  • Offset automatically set from 0 to 4 or 40V in 10/100mV increments by choosing graph view. As an example, 20 mV signals may be viewed superimposed on a 3V DC level.

  • Analogue triggering of the waveform in view with a resolution of 1% of the display height. The analogue trigger may optionally be conditioned with a low pass, high pass or noise filter.

  • Eight digital inputs sampling at 100MSa/sec, threshold adjustable from 0 to 8 V in 10 mV increments. (CS328 only)

  • One external trigger, threshold adjustable from 0 to 20V in 40 mV increments.

  • A hardware trigger system based on a rising or falling edge on any input signal, optionally qualified by a user determined digital input combination and a minimum or maximum trigger duration.

  • A rear panel I/O connector with a 100 Mbit/sec bi-directional LVDS/RS422 link, and three RS422 outputs defaulting to sampling started, trigger received and sampling stopped.

  • Each channel (two analogue, trigger and 8 digital) includes 4M samples of storage, providing up to 40ms of simultaneous storage for all channels, with 10ns resolution.

  • The sample storage may be allocated as between 2 to 1000 frames varying in size from 2M to 4000 samples. These may be used as a history store for reviewing previously captured signals, or to capture up to 1000 trigger events with a minimal 2 s inter-frame delay, while maintaining time relative to the first trigger for all succeeding frames.

  • 25 MHz 5th order anti-alias filter for improved Spectrum Analysis performance.

  • Triggered LED and Power LED on the front panel.

  • Input power range from 6 ~ 12V, 5W provided by a universal mains adaptor.  (cleverscope is not powered from the USB port)

  • Low jitter (1 ps rms) sampling clock for 70 dB spurious free dynamic range.

  • Self calibration to ensure DC performance specifications are met.

  • Two cleverscopes may be stacked to make a 4-channel oscilloscope with 16 digital inputs.

  • Enclosure size: 153 x 195 x 35 mm.

CS300 Application Software

  • Separate, freely moveable and resizable windows to display the signal, a zoomed signal view, the frequency spectrum of the signal, and control panel.

  • The zoomed signal view optionally tracks the signal view cursor.

  • Spectrum analysis with a variety of conditioning windows and display in log or linear format.

  • Each signal window includes a time/amplitude tracer, and two markers for comparison purposes. Colours are user definable.

  • Signal averaging (exponential, block and peak hold) and low pass filtering.

  • Signal measurement, including Peak to Peak, RMS, DC, pulse width, period and frequency.

  • Copy and Paste graphic or data to other applications.

  • Save and Open from disk.

  • User defined units, signal names and scaling (offset and gain).

  • Text annotation of each graph.

  • Web server for remote viewing of LAN connected unit.
