C# SDK x10 probe

Post by Neo_Hypex » Wed Jul 24, 2019 9:35 am

Hi,

I'm using PicoScope 3203D MSO. It has two probes, these probes can be set to x1 or x10.
In the SDK i can not find a option to select x10.
Is it possible to use a probe with x10 option enabled or should i set the probe to x1?

Kind regards,

All you need to do is to multiply the values you get from the SDK by 10 to get the real values.

If i set a trigger, should i also devide the trigger voltage by 10?

Triggers are set as an ADC count, not a voltage so the value needs to reflect where your trigger value sits in the chosen range.

In the sample software there is an function "mv_to_adc(short mv, short ch())" this function is used for calculating the variable "triggerVoltage" wich is used for the "TriggerChannelProperties" which is used as parameter for the function "SetTrigger(......)"

The x1/x10 is an physical switch on the probes it self. Does that not effect the required parameter mv (mv_to_adc(....))?
