  • Page 156: List And Sweep Mode

    A signal generated with varying parameters scans a certain range of varying values of a parameter, with defined start and end points, and can be repeated cyclically. The R&S SMA100B supports two basic methods: ● Sweep mode The instrument generates an RF signal which varies its frequency or level values in discrete steps between the start and end values.
  • Page 157 ® List and Sweep Mode R&S SMA100B Figure 6-2: Schematic representation of a signal generated in list mode (global dwell time) The list mode is especially useful in high-speed measurements with fast changing frequency and level settings. Note that the shown diagrams represent the behaviour in theory. In real signal genera- tion, the instruments usually have a blank time when the frequency or level changes.

  • Page 158: Signal Generation And Triggering In The Sweep And List Modes

    If the dwell time in sweep or list mode is too short or external trigger signals come too fast, the signal generation delays. As the delay increases, the R&S SMA100B signals an overrun, or even stops sweep or list mode signal generation, if the delay gets too long.
