N7614B Signal Studio for Power Amplifier
CFR, DPD and ET Test
Technical Overview
ââ All-in-one test tool for performing power amplifier (PA) test flow with crest factor
reduction (CFR), envelope tracking (ET), and digital pre-distortion (DPD). Supports
narrow-band, wide-band, and dual-band DPD and ET.
ââ User-friendly interface for parameter settings, test flow control and instrument control
ââ Import user-defined I/Q waveforms, signal studio waveforms or free-of-charge pre-loaded
waveforms
ââ PA measurement displays include CCDF, AM-AM, AM-PM, ACP and EVM vs. Power
ââ DPD supports the open-loop model with Look-Up-Table (LUT), the close-loop model
(Volterra and Memory Polynomial), and customer defined DPD algorithms
ââ Time alignment between the ET signal and the RF signal can be calibrated manually or
automatically
ââ Speed improvement to apply LUT-based DPD and shaping table for ET in real-time
