32 How the Digital Signal Interface Module Works Clock source and frequency reference options (a) The DUT supplies the clock. data ESG/PSG module DUT (b) The module supplies the clock. (b) An external clock source supplies the clock. 10 MHz DUT clock reference data clock Or, the ESG supplies a 10-MHz reference ESG/PSG data module DUT 10-MHz reference clock ESG/PSG data module DUT External clock Ext. ref or 10 MHz clock data data clock RULE: The host (ESG/PSG) must always lock to the source of the clock. Use a 10-MHz reference for locking clocks, or supply your own frequency reference(1 to 100 MHz) into the BASEBAND GEN REF IN port of ESG/PSG. Page 32
