This query returns the actual tuner frequency of the QM1004-2-18 in GHz. When in integer mode, the
QM1004-2-18 is only capable of tuning in discrete steps set by the reference divider. As a result, the
actual tuned frequency may vary from the desired frequency set using the
FREQ:TUNE
command. To
achieve the exact desired tune frequeny, the user must use fractional mode or increase the reference
divider value.
Note:
There is a bug in firmware v5.0.0 which results in an incorrect value being returned for this query.
This was fixed in firmware v5.0.1.
