What does AC stand for?

Its ARB memories and signal addition function allow the MG3700A Vector Signal Generator to produce both the desired and interfering signals from a single RF port, so it can measure receiver characteristics such as Adjacent Channel Selectivity or Blocking.

The PowerDPD solution offers the following features: reduces the peak-to-average ratio (PAR) for single-carrier and multi-carrier signals; improves adjacent channel leakage ratio (ACLR) without the need for separate chipset or DSP; enables 45% efficiency using Axis Power Amplifiers; reduces cost for multi-channel MIMO systems; supports single and multicarrier environments; can be used in burst mode systems such as TDD-LTE and TD-SCDMA, the company said.

For 100 GHz dense WDM, the interval between adjacent channels are only 100 GHz, (or 0.

Designers can evaluate the performance of their DVB receiver circuits at the component through system levels using error vector magnitude (EVM), adjacent channel power ratio (ACPR), eye diagrams, and spectral measurements, when stimulated with "real-world" signal impairments, and investigate their effects on receiver sensitivity based on bit-error ratio (BER) to ensure compliance with the DVB standards.

Key features of the NMI500 include 120-dB of variable gain, and greater than 55-dB of adjacent channel selectivity.

The cable-ready, dual-conversion technology uses an adjacent channel rejection function to prevent channels from 'bleeding' over each other.

Using a DVB-T 64 QAM OFDM signal at 90 W average output power, the typical 860 MHz 50 V performance is 28 percent drain efficiency and 23 dB gain, with an adjacent channel power ratio (ACPR) at 4 MHz offset of -62 dBc in a 4 kHz bandwidth.

In presentations to FCC staff in June, Charles Townsend of Aloha and his lawyer also argued against adjacent channel protections that broadcasters have advocated.
