The RTP family of high-performance oscilloscopes combine exceptional signal integrity with a high update rate and multiple instrument capabilities. The whisper-quiet oscilloscopes acquire up to 1 million waveforms per second and perform realtime deembedding to correct transmission losses between the signal source and the oscilloscope. This correction is usually made by filtering the acquired waveforms during postprocessing. With conventional oscilloscopes, this requires a great deal of patience on the part of the user. In contrast, with the RTP, the correction can also be made using flexible filter structures directly after the A/D converters. With that approach, the RTP displays the waveforms without transmission losses, i.e., as they appear at the DUT output; there is no time wasted with lengthy calculations during postprocessing. All these features combine to make the RTP the oscilloscope of choice for debugging – for example when testing electronic systems or highly integrated electronic circuits with high-speed digital or wideband RF interfaces. The oscilloscope comes in three models with different bandwidths: 4 GHz, 6 GHz and 8 GHz.
Another highlight is the RTx-K36 software option for the RTB2000, RTM3000 and RTA4000 oscilloscopes. It can be used to measure the transfer function of active and passive DUTs in terms of gain and phase in the frequency range from 10 Hz to 25 MHz. The oscilloscope's integrated arbitrary waveform generator delivers the stimulus signal. Results, i.e., the gain and phase versus frequency, are plotted as Bode diagrams. The RTx-K36 is especially useful for switched-mode power supplies in order to measure and tune the control loop response and the power supply rejection ratio (PSRR). The amplitude and phase margins can be read directly from the Bode plots.
