Aeroflex Incorporated announced that an upgrade to its 3920 Radio Test Set supports P25 Phase II TDMA test functions and adds features for the development, manufacturing, and field test of both analog and digital private mobile radios (PMRs) and base stations.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
