Reference clock (OCXO)
Access: "Menu" > "Horizontal" > "Setup" tab > "Skew" > "Reference clock" tab.
The oven-controlled crystal oscillator (OCXO) produces a 10 MHz internal reference
signal with precise and stable frequency. With OCXO, you can also use an external ref-
erence signal. The input and output connectors for the external reference signal are on
the rear panel alongside the external trigger input.
Detected
Indicates if the OCXO is detected by the instrument.
Oven hot
Indicates when the oven has reached its nominal temperature and is operating with the
specified accuracy.
External reference
Sets the frequency of an external reference input signal that is connected to the exter-
nal reference input on the rear panel of R&S
RTO6. A frequency range from 1 MHz to
20 MHz is supported.
Remote command:
SENSe[:ROSCillator]:EXTernal:FREQuency
Use external reference
Enables the use of the external reference signal instead of the internal OCXO refer-
ence.
If an external reference is used, the frequency of the reference output signal is the
same as of the reference input signal. Otherwise, the frequency of the reference output
signal is 10 MHz, that is the frequency of the OCXO.
