Signal Monitoring

The RTG UI has signal monitoring capabilities for the user to view the raw I/Q signal and monitor the input and output power.

System Monitor

The system monitor lets the user read the maximum and minimum power of both the input I/Q signal and the output I/Q signal. Users can use these measurements to optimize the digital dynamic range by adjusting the output power of the DUT or the reference level of the RTG. When the user resets the maximum power, RTG overwrites the maximum power register with the maximum power of the signal measured from that point, allowing a new, lower value to be measured as the maximum power. Overflow status can be queried, which indicates clipping of the input or output I/Q signal.

Input Signal Processing

Input signal processing lets the user view the raw I/Q data received by RTG before being processed for target generation. When the user arms the RTG to capture a pulse, RTG gets ready to capture a snapshot of the input I/Q signal and waits for the next pulse. Once armed, RTG captures and saves the samples of the first pulse it detects for a specific period starting from a few samples before the pulse was detected. For this feature to work, Pulse Detection Calibration must be run, which calibrates the threshold levels of the RTG so that it can detect the next pulse on the input signal.

Note This feature only supports pulsed radar signals.
