162 Keysight EXG and MXG X-Series Signal Generators User’s GuideAnalog Modulation (Option UNT)Using an Internal Modulation SourceUsing an Internal Modulation Source1. Preset the signal generator.2. Set the carrier (RF) frequency.3. Set the RF amplitude.4. Configure the modulation:5. Turn on the modulation:The appropriate modulation annunciator displays, indicating that you enabled modulation.6. Turn on the RF output.The RF output LED lights, indicating that the signal is transmitting from the RF output connector.If the modulation does not seem to be working properly, refer to “No Modulation at the RF Output”on page 425.See also “Modulating the Carrier Signal” on page 54.AM FM ΦMa. Press AMb. Set the AM type (Linear or Exponential):AM Type to highlight desired type.c. Set the AM Mode (Normal or Deep).Default is Deep. To select Normalenable More to highlight desiredtype.d. Set the AM Depth: AM Depth >value > unite. Set the rate:More > Setup AM Source >AM Rate > value > frequency unita. Press FM/ΦMb. Set the deviation:FM Dev > value >frequency unitc.
