Ref In / OUT
IN When a 10 MHz external reference signal is detected at this port, it will be used as the instrument frequency reference instead of the internal frequency reference.
OUT This SMB(m) connector outputs a 10 MHz frequency reference signal for use by other modules and test equipment.
Note: To use an external reference signal, you must make a setting in the M937xA.
From the soft front panel, click Utility, then System, then Configure, then check External Reference.
