3. Avoid unnecessary cable lengths and branching points.
Refer to Figure 9-3 for an example of how to connect two instruments for achieving
phase coherence. The configuration can be extended by further instruments.
Figure 9-3: Example of a setup: LO coupling
To configure the first instrument in the chain
1. In the "Frequency / Phase > Local Oscillator (LO) Coupling" dialog, select "LO
Source > Internal".
2. In the "Frequency / Phase > Local Oscillator (LO) Coupling" dialog, select "REF/LO
Output > LO".
3. If an external reference frequency is used, select "SGMA-GUI > Instrument Name
> Reference Oscillator > Source > External".
To configure next instruments
1. In the "Frequency / Phase > Local Oscillator (LO) Coupling" dialog, select "LO
Source > External".
2. In the "Frequency / Phase > Local Oscillator (LO) Coupling" dialog, select "REF/LO
Output > LO".
9.8 How to Restore the LAN Connection to an Instrument
► If the LAN connection to an instrument configured to use a static IP address is lost,
press the [LAN LED] on the instrument's front panel for more than 3 seconds to
