Using Analog Modulation (Option UNT Only)The Basic ProcedureThe Basic Procedure1. Preset the signal generator.2. Set the carrier (RF) frequency.3. Set the RF amplitude.4. Configure the modulation: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 Normal enableMore to highlight desired type.d. Set the AM Depth: AM Depth > valueDefault 0.01%Range 0.01 to 100%e. Set the rate:AM Rate > value > frequency unita. Press FM/ΦMb. Set the deviation:FM Dev > value > frequency unitc. Set the rate:FM Rate > value > frequency unita. Press FM/ΦM > FM ΦMb. Set the BW (normal or high):FM ΦM to highlight desired typec. Set the deviation:ΦMDev > value > pi radd. Set the rate:ΦM Rate > value > frequency unit5. Turn on the modulation:AM FM ΦMAM Off On softkey to On FM Off On softkey to On ΦM Off On softkey to OnThe 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 316.See also “Modulating the Carrier Signal” on page 61.78 Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide
