A is a USB connected PC based mixed signal oscilloscope, spectrum analyser, and signal generator
which brings benefits to the user that are unavailable from traditional stand-alone oscilloscopes. This innovative approach
delivers an unbeatable combination of affordability, ease of use and documentation of test results with the simple “Copy”
and “Paste” facility. Graphs and data can be copied and pasted to other applications, saved or loaded from disk, and printed.
Cleverscope hardware resources include:
•Two 10 bit, 12bit, or 14 bit analog channels sampling simultaneously at 100 MSa/s. AC or DC coupled. The bit
resolution is field upgradeable by changing the sampler circuit board.
•Scaling and offsetting to view 50mV full scale offset to any value between –8 and +8 V.
oGain automatically set from 20mV full scale to 800V full scale by choosing graph view and probe switch setting.
oOffset automatically set from 0 to ±4 or 40V in 10/100 mV increments by choosing graph view. As an example
20 mV signals may be viewed superimposed on a 3V DC level.
•Analog triggering of the waveform in view with a resolution of 1% of the display height. The analog trigger may
optionally be conditioned with a low pass, high pass or noise filter.
•One external trigger, threshold adjustable from 0 to ±20V in 40 mV increments.
•Eight digital inputs sampling at 100 MSa/s, threshold adjustable from 0 to 8 V in 10 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/s bi-directional LVDS/RS422 link, and three RS422 outputs defaulting
to sampling started, trigger received and sampling stopped.
•Each channel (two analog, trigger and 8 digital) includes 4M samples of storage, providing up to 40 ms of
simultaneous storage for all channels, with 10 ns resolution.
oThe 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 µs 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.
•Low jitter (1 ps rms) sampling clock for 70 dB spurious free dynamic range.
•Self calibration to ensure DC performance specifications is met.
•An optional plug-in signal generator, 0-10MHz, sine, square or triangle.
•Enclosure size: 153 x 195 x 35 mm.
Cleverscope software resources include:
•Separate, freely moveable and resizable windows to display the signal, a zoomed signal view, and the frequency
spectrum of the signal, and control panel.
oThe 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.
•Full mathematical functions including + - / * sqrt integral differential and 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.
