CONFigure:CHECk[<expected value>, <resolution>]
DESCRIPTION:
This command connects the standard frequency in use to the
counting input and takes frequency measurements. The
higher the resolution selected, the longer the gate time and
hence more of the counting chain is checked. The result
must be 10 MHz exactly for no error. Note that this function
can return the error –300 ("Basic self-check failure") in place
of the 10MHz result to indicate certain hardware failures.
Note: This function must be selected to perform functional
tests. Refer to the commands in the TEST sub-system.
The optional <expected value> and <resolution> parameters
are used to derive the required number of digits of resolution.
Their units are Hertz.
INITIALIZATION:
*RST Resolution = 8
EXAMPLE:
"CONFigure:CHECk"
Configures the 2461 TYPE C to measure the frequency
standard.
