PICO2206A Help

Post by walterlee » Thu Jul 14, 2016 3:07 pm

Hi there,


I am using PICO2206A and I noticed that the timebase in PicoScope2000aGetRapidBlock.vi unable to set to units I want for example, 400ms, 400us and etc. Possible to let me know how to do it?

In addition, I had collected data using PicoScope2000aGetRapidBlock.vi, the return value is ADC value(I guess). Any idea how to do it in Voltage value?

Many Thanks.
Walter.

You will need to scale the value using the current voltage range used by SetChannel and the Maximum ADC count which can be retrieved using

Code: Select all

ps2000aMaximumValue
PICO_STATUS ps2000aMaximumValue (
short handle
short * value
)
This function returns the maximum ADC count returned by calls to get values.
To work out the timebase you need to use the forumula

Code: Select all

(timebase - 2) / 62,500,000 = sample interval
