Test and Measurement Forum

Hello! I am looking for an oscilloscope that able to capture the raw data at the below specification:

1) Bandwidth: 50MHz per channel or 100MHz for 2 channels, simultaneous
2) Time resolution: 10ns
3) Time span needed to measure: minimum 20us at interval of 1KHz
4) Triggering Mode: External trigger
5) Support C# programming

We intended to captures a 20us signal of time span after receiving the external trigger pulse at every 1ms interval.
For my application side, we can't afford to miss any signal that the trigger pulse event have been occurred. Beside that, I am worry about the dead time after the scope being captured. If this issue happens, it will cause to miss the next trigger event.

Can anyone provide suggestion of what model of oscilloscope meet my application?

Thanks in advance
Adam

Dear Adam,

Thank-you for your inquiry with regard to a scope suitable for your application.

Please proceed to the following link for details for details of PicoScope 4226 and 4227 which are precision USB oscilloscopes that are suitable for general, scientific and field-service use. With 12-bit resolution (adjustable up to 16 bits in enhanced resolution mode) and 1% accuracy.

In order to achieve your requirements will be able to use rapid block mode functionality.

In normal block mode, the PicoScope 4000 series scopes collect one waveform at a time. You start the the device running, wait until all samples are collected by the device, and then download the data to the PC or start another run. There is a time overhead of tens of milliseconds associated with starting a run, causing a gap between waveforms. When you collect data from the device, there is another minimum time overhead which is most noticeable when using a small number of samples.
Rapid block mode allows you to sample several waveforms at a time with the minimum time between waveforms. It reduces the gap from milliseconds to about 2.5 microseconds.

Kindest regards,
