1 = Start value
2 = Stop value
3 = Step size
●
Triangle
The sweep sequence resembles a triangle. One sweep runs from start to stop
value frequency and back. Each subsequent sweep starts at the start value.

1 = Start value
2 = Stop value
3 = Step size
The current frequency or level of an RF frequency, level or LF frequency sweep is
determined by the shape (e.g. sawtooth or triangle) and the spacing (linear or logarith-
mic), and the step size.
8.7.3 About List Mode
The list mode is used to generate the RF signal based on a set of predefined fre-
quency and amplitude value pairs, with individual step times. You can define the values
arbitrarily, in any order and varying step sizes, within the entire configurable value
range of the instrument.
Configuration and operation of list mode signals
The parameters configuring the RF signal are defined in a list (table) and stored in a
file.
Creating and handling lists
List files can be created in the following ways:
●
Internally
Use the build-in table editor with columns for the frequency-level values pairs and
the dwell time.
Define the values manually (row by row) or automatically, based on value range
and step size.
