SENSe:ROSCillator: | SOURce | CATalog? |
Learn about the Reference Osc.
See the rear-panel 10 MHz connector.
Applicable Models: N522xB, N524xB (Read-Write) Enables selecting between locking to an external reference without the ability to change the reference frequency, or select internal or external reference with the ability to change the reference frequency. |
|
Parameters |
|
<bool> |
ON (or 1) This is the default behavior which locks to an external reference without the ability to change the reference frequency. OFF (or 0) Leaves the reference in its current state and all changes to the reference behavior must be made through the SCPI commands in this topic or by using the Reference dialog. |

Applicable Models: M980xA, P50xxA/B, P93xxB,, N522xB, N524xB (Read-Write) Set and read Reference Oscillator frequency at the reference input connector. 100 MHz reference is typical for M980xA, P50xxA/B, and P93xxB. |

Applicable Models: M937xA, P93xxA/B, M98xxA, P50xxA/B, N522xB, N524xB (Read-Write) Set and read the Reference Oscillator state. Note: The state can only be set on instruments with Synthesizer Version 7.0 and greater. Instruments with Synthesizer Version 6.0 and earlier can only be queried. Use the SYSTem:CONFigure:REVision:PNA:SYNThesizer:VERSion? command to find the Synthesizer Version. Using the GUI, click on Help -> About NA... to find the Synthesizer Version. Note: This setting is NOT cleared with Preset. However, it does clear when the M937xA software is restarted. Note: Using the signal from PXI Chassis backplane degrades the measurement performance especially absolute measurement. This is due to worse phase noise on the reference signal from backplane. |

Parameters |
|
<state> |
Choose from the following: The SENSe:ROSCillator:SOURce:CATalog? returns the available reference oscillators INTernal - Use the internal Reference Oscillator. EXTernal - Use an external Reference Oscillator. Use SENSe:ROSCillator:SOURce:CONDition? to determine if the analyzer is locked to the external oscillator. PXIBackplane - Use an an external Reference Oscillator via PXI Chassis backplane (PXI only) |

Applicable Models: M937xA, P93xxB, M98xxA, P50xxA/B, N522xB, N524xB (Read-only) Reads the 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. |
