CLOCK SOURCE Selection of clock source.INT SMIQ uses internally generated clock signals.EXT An external symbol clock or bit clock is fed inat connectors SYMBOL CLOCK or BITCLOCK. The clock synthesizer on themodulation coder is synchronized to thisclock.The symbol rate has to be set with anaccuracy of ± 1 %.The polarity, the trigger threshold and theinput resistance of the clock inputs can bemodified in menu DIGITAL MOD - EXTINPUTS.IEC/IEEE-bus command :SOUR:DECT:CLOC:SOUR INTDELAYSetting the delay of generated modulation signal to anexternal clock.This can be used, for example, for synchronization with asecond unit to achieve time synchronization between themodulation signals of the two units.IEC/IEEE-bus command :SOUR:DECT:CLOC:DEL 0.51125.5555.03 2.326E-9
