DC Sample Precision Select
Syntax:
SPREC <prec>
Parameters:
The parameter <prec> is of type <number> with acceptable values of 20000 or
4096.
Function:
The 2835-C has a 20,000 count high precision A/D and a 4,096 count A/D. This
command determines which of these A/Ds will be used from both channels to
acquire samples during DC single and DC continuous acquisition modes. This
command affects the available range of DC sample frequencies.
Note that the 4,096 count A/D is used during all other acquisition modes.

Syntax:
SPREC?
Parameters:
None
Function:
This query returns a string that indicates whether the 20,000 count A/D or the

on both channels.
Returns:
<prec>
<prec> is of type <number>. It will be 20000 if the 20,000 count A/D is selected
and 4096 if the 4,096 count A/D is selected.
