ETS sampling in ADC-212

Postby Guest » Tue Dec 12, 2006 1:22 pm

According to specifications page in your web site, ADC-212 supports ETS up to 5 GS/s provided you have PicoScope release R5.08.0 or later. :D

However using the latest version of PicoScope available in your web site (5.15.6) does not show ETS option in trigger menu bar when ADC-212 converter is selected, while selectting 3000 series device makes this option available. :shock:

So, i am very confused with ETS suport of ADC-212

Hi, thank you for your post. Are you using the ADC212/3 as this one does not support ETS. Only the ADC212/50 and ADC212/100 support the ETS. If you have any further questions please do not hesitate to contact me.

Kind regards

OK. In fact, i am to buy an ADC-212/100 but currently, i am using a 3204, so i was testing PicoScope selecting ADC-212. As long as software was not able to find an actual ADC-212 device, maybe toolbars was configured for worst case (212/3), so ETS option was not available.

However, looking at programming reference for both 3200 and ADC-212 available in your web site, i could find API functions for dealing with ETS in 3200 (ps3000_set_ets() and ps3000_get_times_and_values()) while equivalent functions are missing in ADC-212 reference. Since ETS requieres critical timing in sampling hardware, i think it is not possible to implement ETS only in PicoScope software but, hardware support is needed. Maybe documentation is not up to date.
This is a link of programming guide found on your web site: "document/pdf/adc2xx.pdf". As you see, only one document is available for all ADC-2XX products.
:wink:
Thanks.

Hi

Thank you for your post.

Yes, without a unit connected it will default to a 212/3 and thus not show ETS support.

The function adc200_set_ets does exist and documentation on this exists in the file adc2x044.hlp which is installed with the drivers and examples for the ADC-212.

Best Regards
Sarah
