Description of command

FW vers.

This command is always a query. It indicates whether the CMU is synchronized to the (external) reference frequency.

Note:

After activating the external reference frequency (command CONFigure:SYNChronize :FREQuency:REFerence:MODE EXTernal) it is necessary to allow for a setting time (~1 s) until the CMU has synchronized. In this case it is recommended to check whether the reference frequency is locked before starting a measurement in remote control mode.
