QM1004A-2-18 Combined RF Upconverter/Downconverter
User Manual
6.6 SYSTem:READstate? [0-5]
This query allows the user to read the parameters of the stored states without changing any internal reg-
isters. The query output is a list of parameters for the selected state. If no state parameter is given, the
returned state is state 0. The list of state parameters contains comma separated values, without spaces,
in the following order:
Tune Frequency, RF Power State, LNA Power State, Reference Frequency, Exter-
nal Reference Enabled, External Referece Switch Override, PLL Mode, Reference Divider, Upconverter
Attenuation, and Downconverter Attenuation
. See the respective command definitions for descriptions of
each parameter.
