External Timebase Reference (Option 001)
Option 001 is the External Timebase Reference, which provides rear
panel connectors (10 MHz In and 10 MHz Out) and circuitry to allow
synchronization between multiple Keysight 33210A function generators
or to an external 10 MHz clock signal. You can also set the phase offset
of the output waveform from the front panel or over the remote
interface. To synchronize multiple 33210As, all of them must have
Option 001 installed.
To align the phase of two 33210As, you can use a dual-channel
oscilloscope to compare the output signals:
1. Connect two 33210As, with 10 MHz Out connected to 10 MHz In:
2. Connect the outputs of the 33210As to the scope channel inputs:
3. Set the same frequency on both function generators. The scope should
show the signals to be in sync with regard frequency, but not phase.
(A square wave works well to show the phase difference.)
