Basics of Vector Signal Generators Part 2: Waveform playback mode

White Papers

In Part 1, we explored real-time waveform generation, which enables verification of receiver designs in all stages, from baseband subsystem coding to sensitivity tests. We also looked at each component in a baseband generator. In addition, we discussed additive white Gaussian noise (AWGN) and channel emulation for simulating realistic channel conditions between a transmitter and a receiver. These enable receiver performance and functionality testing during radio-frequency (RF) and baseband integration or system-level tests.


The real-time waveform generation mode characterizes the receiver performance of specific wireless standards. But not all wireless standards require such a long-period signal for receiver testing. For example, Wi-Fi IEEE 802.11ax specifies the minimum input sensitivity with a certain package error rate. The signal is in a packet and frame format. You can generate a waveform segment that includes one or several packets, then repeat the segment. The receiver gets the signal and uses cyclic error-correcting coding to determine whether each packet is corrupted.
