CS328A

CS328A is a USB 2.0 mixed signal PC oscilloscope which brings benefits to the user that are unavailable from traditional stand-alone oscilloscopes.
Its innovative approach delivers an unbeatable combination of affordability, ease of use and documentation of test results with the simple 〝Copy and Paste〞 facility.

CS328A is a USB connected, PC hosted oscilloscope and spectrum analyser with PC based application software.

CS328A Acquisition Unit

• Two 10, 12 or 14 bit analog channels sampling simultaneously at 100 MSa/sec. AC or DC coupled.
• USB 2.0 Interface to the PC or 10/100Mbit ethernet, depending on option
• Gain automatically set from 20mV full scale to 800V full scale by choosing graph view and probe switch setting.
• Offset automatically set to correspond to the selected amplitude axis view. As an example a graph with amplitude axis of 2.40 to 2.42V automatically chooses a 20mV range offset by +2.40V - good for looking at small signals in single supply op-amp applications.
• 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/sec, 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/sec bi-directional LVDS/RS422 link, and three RS422 outputs defaulting to sampling started, trigger received and sampling stopped.
• Each channel (two analog, ext trigger and eight digital) includes 4 or 8M samples of storage, providing up to 40 ms of simultaneous storage for each channel, with 10 ns resolution.
• The sample storage may be allocated as between 2 to 3000 frames varying in size from 4M to 2000 samples. These may be used as a history store for reviewing previously captured signals, or to capture up to 3000 trigger events with a minimal inter-frame delay, while maintaining time relative to the first trigger for all succeeding frames.
• 20 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, 6W 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 are met.
• 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, and 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.
