compare 6407 & 9302-15

Post by WallaceC »

Hi all,
My team is going to develop a product with Ethernet/RMII, USB HS, SPI, I2S, I2C bus. We have to get compliance. So I am interested in your product to do pre-compliance test before test in laboratory. We have to test single end and differential (USB HS) eye diagram and check any overshoot and cause EMC problem. I would like to know your advice which one 6407 or 9302-15 is better choice. What's the pros and cons? Thank you very much.

Dear Wallace,

Thanks for your inquiry with regard to the 6407 and the 9300 from Pico Technology. As discussed in your previous post I would like to arrange a conference call to discuss your application in detail.

The 6407 is a real time DSO and the 9300 is a sampling scope.

Digital storage oscilloscopes (DSOs) work by sampling the input signal at regular intervals. The samples are then reconstructed to draw a picture of the signal.

A sampling oscilloscope is a special type of oscilloscope that uses a technique called sequential time sampling. This type of sampling is best suited to repetitive waveforms or those that are derived from a regular clock, such as serial data streams, clock waveforms and pulses in digital circuits, semiconductor test patterns, and amplifier pulse-response and rise-time tests. Signals like these tend to have very high bandwidths or high data rates. A sampling scope captures just one sample from one trigger event, typically a single cycle of the waveform or clock, and then repeats the process over a large number of cycles, varying the timing of the sample by a small increment from one sample to the next. The resulting collection of samples is then assembled into a picture of a typical cycle.

The advantage of a sampling scope is that even with input signals in the gigahertz range, the output of the sampler is at a much lower frequency, typically in the audio frequency band. This allows high-fidelity, low-frequency amplifiers and ADCs to be used to capture the signal. For example, the PicoScope 9300 Series can capture waveforms up to 20 GHz with high precision (16-bit resolution before scaling and processing). A real-time DSO that could capture a single cycle of the same 20 GHz waveform would be prohibitively expensive.

I look forward to your response in this matter.

Kindest regards,

Stuart Murlis
