Voltage ranges in 2000a guide is missing a range

Post by JavaChips »

Hi all,

I am writing a Java program to run my PicoScope 2206B in block mode. I struggled for a couple hours on figuring out why my ADC counts are always capping at half the voltage range I set the channel to (I wanted +/- 2 V, but the ADC counts capped at +/- 1V).

I finally realized that the int I pass in for my variable "range" is actually one less. As I was scrolling through some forums, I see that the voltage ranges actually start with +/- 10mV. However, when I go back to the 2000a Series Programmer's Guide, on the page for ps2000aSetChannel(), the voltage ranges start at +/- 20mV.

I conclude that I was missing the +/- 10mV in my enumeration, but I wouldn't have known without digging through the forum. It would be great if you could update the Programmer's Guide so that others will not have to encounter the same mistake.

Best,
JavaChips
