Re: Picoscope 2205 post-trigger delay questions

Hi again, Robin! I'm aware that collecting several continuous blocks would have a small gap in between. That's why I'm trying to use post-trigger delays, so that I can collect the parts of the waveform only whenever the scope is re-triggered again since the echo waveform is periodic (period of 300 H...

Re: Picoscope 2205 post-trigger delay questions

Hi Robin! It seems that I forgot to place my image file from before. The image is the waveform that I have to process. The waveform is periodic, with the first big "pulse" to serve as the trigger event for data collection in the picoscope 2205. The waveform needs to be sampled at a high sampling rat...

Picoscope 2205 post-trigger delay questions

Hi, the programmer's guide states that the post-trigger delay can be set to -100% to 100% of the requested number of data points. Does this mean that the post-trigger delay is dependent on the number of samples? Is it not possible to set the post-trigger delay to a specific amount of time, say 10us?...

Re: Pico 2000 fast streaming/block mode questions

Hi Robin, thanks for the quick reply! I still got a few questions though... I can use block mode to collect a few thousand samples every 10 ns, right? But since I need to continuously collect samples up to 100,000+ data points, I would then have to call run_block and get_values a few times. However,...

Pico 2000 fast streaming/block mode questions

Hi, I need to be able to use a picoscope 2205 to collect data of about 100,000 samples or more, with an interval of around 10-100ns between samples. My question is: is it really possible to use fast streaming to sample at a period less than 1us using the picoscope 2205 model? I tried testing smaller...

set_sig_gen_built_in function using python interface

Hi! I tried dolhop's ps2000 partial python interface, and it worked very nicely on the ps2205! Unfortunately, I need to create a python application that requires the picoscope's signal generator, and the interface for the ps2000_set_sig_gen_built_in() was not yet implemented... so I tried adding it ...
