G3 Vector Signal Generator Keysight IQ Data Format and Device Upload
应用文章
The G3 Vector Signal Generator is an ultra-fast-switching vector-modulated signal generator with an internal I / Q modulator. Customized IQ data can be loaded into internal memory and selected segments of the memory can be played back to modulate the output signal.
Marker bits can be used to wait for trigger events or to generate trigger signals (on the MF output ports). If multiple waveforms are stored in the memory as multiple segments, it is not possible to mix segments with and without maker bits.
The application note explains the file format that must be used to store IQ values and markers. The files can be processed by the G3 Vector Signal Generator graphical user interface to upload the data. The file format is also used by the G3 Vector Signal Generator graphical user interface to export synthesized data.
The second part of the document shows how IQ values and markers can be uploaded to the G3 Vector Signal Generator using SCPI commands with an example written in Python.
