SENSe:ROSCillator:SOURce?

Applicable Models: N522xB, N523xB, N524xB, E5080A (Read-only) Applying a 10 MHz signal to the Reference Oscillator connector automatically sets the Reference Oscillator to EXTernal. This command allows you to check that it worked. EXT is returned when a signal is present at the 10 MHz Reference Oscillator connector. INT is returned when NO signal is present at the 10 MHz Reference Oscillator connector.

SENSe:ROSCillator:SOURce <state>

Applicable Models: M937xA, P937xA (Write-only) Set and read 10 MHz Reference Oscillator state. Note: This setting is NOT cleared with Preset. However, it does clear when the M937xA software is restarted.
Parameters
<state>	Choose from the following: INTernal - Use the internal 10 MHz Reference Oscillator EXTernal - Use an external Reference Oscillator. Use SENSe:ROSCillator:SOURce:CONDition? to determine if the M937xA is locked to the external oscillator.

SENSe:ROSCillator:SOURce:CONDition?

Applicable Models: M937xA, P937xA (Read-only) Reads the 10 MHz Reference Oscillator 'locked' condition. When SENS:ROSC:SOUR is set to Internal, this command will always return "LOCKed". When SENS:ROSC:SOUR is set to External, then this function takes about 100 usec to read the state of the hardware.
