19. 19 Output Units Output units: –Vpp –Vrms –dBm The default is Vpp dBm unit will not apply to ‘ high impedance ’ output termination

20. 20 Agenda Introduction Core Technology and Waveform Capabilities Instrument Advanced Functions

21. 21 Output Termination The output termination can be changed to “high impedance” –Press  select the ‘Output Setup’ softkey  –Press the ‘Load’ softkey and then choose “High Z” The default output termination is 50 Ω The output signal amplitude is twice the setting value if terminating into an open circuit

22. 22 External Frequency Reference –Synchronisation allowed to an external clock (typically10 MHz), to another function generator –Phase adjustments can be made from the front panel or via a computer interface, allowing precise phase calibration and adjustment –Connect two or more Function Generators to create a multi- channel waveform generator The generators using common clock signals and common trigger signal

23. 23 Arbitrary Waveform Software –Creating, editing, and downloading complex waveforms using the waveform editor is easy –Example: Keysight IntuiLink™ Waveform Editor –Capturing a waveform using IntuiLink™ for Oscilloscope before sending it to the Keysight 33220A for output is possible
