   AEROFLEX - WEINSCHEL 8331   Description / Specification:    
AEROFLEX - WEINSCHEL 8331 Programmable Attenuator Series

The Weinschel 8331 Series Programmable Attenuator Units offer a lower cost solution for automated bench test and subsystem applications. Standard 8331 Series designs house and control various Weinschel Programmable Attenuator Models (3200-XE, 3400, 150T, and 4200 Series) via ethernet, USB 2.0 and Serial communications interfaces.
Most 8331 Series are multi-channel configurations where RF signal is routed through either the front or rear mounted Ports. This series can be configured for up to 12 independent channels of attenuation. Multiple programmable attenuators can be used in conjuction with other coaxial devices such as switches, power combiners, directional couplers, and filters creating various multichannel test configurations.

Provides a flexible, easy to program, low cost solution for your bench test/calibration setups and subsystem applications.
Multi-Channel attenuation paths (up to 12 channels)

Average Power
Average power means that the energy transfer rate is to be averaged over many periods of the lowest frequency involved. For a CW signal, the lowest frequency and highest frequency are the same, so average power and power are the same. For an amplitude modulated wave, the power must be averaged over many periods of the modulation component of the signal as well.

A harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency, i.e. if the fundamental frequency is f, the harmonics have frequencies 2f, 3f, 4f, . . . etc.

Phase Noise
Phase noise is the frequency domain representation of rapid, short-term, random fluctuations in the phase of a waveform, caused by time domain instabilities. Phase noise (L(f)) is typically expressed in units of dBc/Hz, representing the noise power relative to the carrier contained in a 1 Hz bandwidth centered at a certain offsets from the carrier.
