Descrizione
Key Facts- Automatic envelope voltage adaption enables power sweeps with automatic recalculation of the envelope signal
- Enables generation of RF and envelope signal out of one box, no second hardware needed for the envelope calculation
- Envelope is calculated in real-time from the current I/Q signal, any signal configuration changes are effective immediately
- Fully synchronous envelope and RF signal with adjustable delay (+- 500ns, resolution 1 ps)
- Envelope shaping in real-time with flexible shaping functions (i.e. linear, from table, polynomial, detroughing)
- Any user I/Q (ARB) waveform can be used.
- High performance analog outputs ensure Envelope generation with best spectral purity
Brief Description Envelope tracking is a technique to increase power amplifier (PA) efficiency by modulating the DC supply voltage according to the envelope of the IQ signal. For test and verification of DC Modulators and Envelope tracking power amplifiers (ETPA) several measurement challenges occur. At the PA a high-precise synchronization between the envelope and the RF signal is required. To avoid additional noise introduction best spectral purity for the envelope signal is needed. In addition envelope shaping is applied to get a trade-off between efficiency and linearity. For level sweeps and PA dynamic range tests automatic recalculation of the Envelope signal is required. The R&S®SGT-K540 Option Envelope Tracking provides solutions to all of these challenges. It enables the capability to generate the envelope of any IQ data in real time and output it at the analog interface with highest spectral purity. As RF and Envelope is generated within the same instrument, no additional cabling for synchronization is required and no added jitter occurs thus 100 % repeatability is provided. The RF to envelope delay adjustment can be performed in real-time within ps resolution. Several envelope shaping capabilities (i.e. table, polynomial, detroughing) are also implemented. A unique feature of the R&S®SGT-K540 Option is the automatic envelope voltage adaption for simplifying the setup and avoiding time consuming adjustments for different power levels.''
