OK, will keep trying.
Signed 4 byte number, maximum value of 65535. I may try unsigned 2 byte
number as well then.
I'm slightly surprised that setting the number of samples is not done by a
SetOption() command. After all, there is a
GetOption(I1_NUMBER_OF_AVAILABLE_SAMPLES) (which they say is read only).
Is "2009" the same as " "IntegrationTime"?
Right. Time for some experiments.
Regards,
Bill

I'd imagine it is a 32 bit signed int, with a maximum value of 65535.
I understand that you can get the current sample time for a particular mode
using I1_GetOption("2009") [Should be around "0.010" for Rev A, and about
half that for Rev B or Rev D), and the total measurement time should be be
that number times the I1_TriggerCountedScan() parameter.

I think sip* is for a different instrument (one of the Sequel Chroma
colorimeters ?).
