Which product?

Hi am looking for advice on which product to buy, I have used your ADC10 and ADC12 products, but now require a device that will allow a 0-10V range - only needs to be single chanel. which do you suggest?

Hi

Thank you for your post.

I would recommend that the ADC-212/3 might suit your application best.

If you are looking to be able to input a 0 to 10V signal without using any attenuation then this is the best option. It is a dual channel scope and will enable you to input ±20V.

The other way of being able to input 0 to 10V would be to use a potential divider and then input this into the ADC-10 or ADC-12.

Hope this helps

Best Regards
Sarah

Hi,
I am also unsure which product to use .
I am trying to datalog dc voltage and dc current.
They vary between 54.8 V and 67.5 V and the current is in between 10.41 and 11.25A.
What to use?

Hi

Thank you for your post.

For this application you would need to use an attenuating probe for the voltage, and I would advise using a current clamp for the current. You could also use our ADC-212/3 and then have a probe on one channel and a 60A current clamp on the other channel.

Hope this helps

Which product (high speed)

Postby Fyodor » Wed May 04, 2005 7:11 am

I would like to use a two channel A/D converter. The speed should be at least 300 KSPS and this rate should be streaming, I mean I should be able to get at least 2 seconds of measurement without any interrupt and the readings should be equally distributed over time. I thought of using AD-216 but 32 KB buffer is just not enough, since it will only give me 0,05 second streaming data for 2 channels at 300KSPS. PicoScope 3000 looks fine but I guess it would be very expensive to buy a device working at GSPS rates for usage at 300 KSPS.

Thank you for your help

Hi

Thank you for your post.

You could use the PS3000 range, however this is only capable of streaming at speeds of up to 1kS/s. This therefore would not be fast enough for you. You could however use it for the larger buffer and longer record time, but this would not be streaming.

I would suggest that the PS3000 is the best range to use as they have a better streaming capability, bigger buffers, and faster download time to the PC.

Hope this helps

Best Regards
Sarah
