15.1.4 Arbitrary waveforms
The arbitrary waveform generator allows you to output a user-defined waveform for
testing your devices. An arbitrary waveform is copied from an existing waveform on the
instrument, or loaded from file. You can load CSV files that follow a defined structure,
or saved reference waveforms.
See also: Chapter 15.3.4, "Configuring an arbitrary waveform", on page 449.
15.1.4.1 Arbitrary waveform files
You can load CSV files that have a Rohde & Schwarz WaveGen format.
Content and format of the Rohde & Schwarz arbitrary waveform CSV files
The waveform generator format can contain the following values:
●
Rate
●
Time value
●
Voltage value
If all the values are defined, the file format is as follows:
Rate = 5000000 //Sample rate of the arbitrary waveform.
0.000000E+000,-5.995 //Time value 1, Voltage value 1
1.237011E-005,-6.0 //Time value 2, Voltage value 2
.......
In this case, the rate is reflected in the "Sample Rate" field of the user interface. The
total number of Time/Voltage values is reflected in the "Samples" of the user interface.
Anything written after // is ignored as a comment.
You can define only some of the values. According to what you define, the file format
looks different and is handled differently:
●
With specified Rate:
