General

IMPULSIVE NOISE SIGNAL GENERATOR 1908A This unit is impulsive noise generator that can conduct impulse noise test (Burst noise test) regulated by standard, such as DVB-T, ATSC, DOCSIS and etc. By input of IF signal to this unit, addition of impulse noise and phase noise corresponding to C/N setting and frequency conversion are made and outp g ut is made as RF signal. Also, without input of IF to this unit, this unit can be used as noise generator (Max. NBW=100MHz) that outputs only noise centering setting frequency. Every parameter needed for impulse noise and phase noise measurement can be set easily, so that this unit is most appropriate for performance evaluation of receiver.

Features
Possible to set 4 pulse noise parameters.
(a) PD(Pulse Duration) (b) PS(Pulse Spacing)
(c) BS(Burst Spacing) (d) Pulse Per Burst
・Possible to select Possible to select “Impulse Impulse” and “Continuous Continuous .”By using unit with “Continuous” condition, usage as AWGN generator is possible.

・Setting of phase noise mask is made by calling out profile pre-set in advance.
Making of profile data is made by defining phase noise value of 5 points that are off set
100Hz, 1KHz, 10KHz, 100KHz and1MHz from carrier.
・Output noise band width : 6 kinds of 100, 24, 8, 6, 4 and 2 MHz.
・IF input frequency : 36~44MHz (1 Hz step)
・RF output frequency : 30~2150MHz (1 Hz step)
・RF output level : 0 ~ -110dBm ( p 0.1dB step)
・C/N setting range : -35~+40dB (0.1dB step)
・Impulsive noise test and phase noise test corresponded to following standards are possible.
