Also new from Keysight is its M9383A PXIe Microwave Signal Generator, which is a compact modular instrument that provides frequency coverage from 1 MHz to 44 GHz, up to 1 GHz modulation bandwidth with an internal baseband generator, and over 2 GHz RF modulation bandwidth with external I/Q inputs.
It occupies only 1RU space and monitors input RF modulation parameters and signal performance metrics including Modulation Error Ratio (MER) and Low Density Parity Check (LDPC) status.
value is 5 dB), m the RF modulation index defined as m = ([pi] x [V.sub.RF]/2[V.sub.[pi]]), [J.sub.n](*) is the nth-order Bessel function of the first kind, and [V.sub.[pi]] the half-wave voltage of the two sub-MZMs.

The possibility of RF health effects has been investigated in epidemiology studies of cellular telephone users and workers in RF occupations, in experiments with animals exposed to cell-phone RF, and via biophysical consideration of cell-phone RF electric-field intensity and the effect of RF modulation schemes.
