Digital pre-distortion (DPD) is a common method to linearize the output signal of a power amplifier (PA), which is being operated in its non-linear operating range.Most PAs operate in their non-linear range for efficiency reasons. The drawback of higher efficiency is the non-linear operating range. In order to maintain signal quality, many transmitters employ DPD. Implementing real-time DPD in a transmitter is a challenging task and often ends in PA models, which are specific to the signal transmitted.Even though these complex models are required for transmitter development, they are not needed during PA verification and development.This article describes an approach to generate a pre-distorted signal based on a hard-clipper. The resulting waveform pushes the output of the DUT as close to the hard-clipper as possible.Due to the waveform approach, the algorithm compensates all memory effects.

RF pulse measurements, to characterize the signal in the frequency domain, are traditionally carried out on an RF spectrum analyzer. For time related pulse parameters, oscilloscopes are widely used. However, the measurement capabilities of state of the art test and measurement equipment has evolved over time and crosses domains. With a combination of R&S®RTO digital oscilloscope and dedicated pulse analysis software R&S®VSE-K6, pulse signals can be analyzed in both domains, frequency and time.The R&S®RTO digital oscilloscopes are unique in that they allow output of I/Q data for processing. This application note focusses on signal measurement using this instrument.Analysis of an L-/S-band ATC RADAR utilizing the R&S®RTO2044 oscilloscope running Vector Signal Explorer Software R&S®VSE and Pulse Analysis personality R&S®VSE-K6 is followed by measurements on an X-band RADAR utilizing R&S®FSW, R&S®FPS, R&S®FSV or FSVA signal & spectrum analyzers with the same dedicated R&S®VSE-K6 software.
