Rear panel connections
10 MHz Out and In connectors
The 10 MHz Out connector delivers a 10 MHz single-phase signal locked to the internal instrument
clock. The 10 MHz In connector accepts an external 10 MHz clock signal. You can use these
connections to synchronize multiple instruments and control phase offset.
To set up 10 MHz Out and In from a remote interface:
Use this command to specify degrees or radians:
UNIT:ANGLe {DEGree|RADian}
Use this command to specify the phase offset of the output waveform. This value can be set in
degrees or radians as specified by the UNIT:ANGL command:
PHASe {<angle>|MINimum|MAXimum}
