Spirent NSA-400 ADSL Noise Impairment Generator
The NSA 400 consists of seven discrete generation sections. The features associated
with one generator operate independently of the others. However, the options within a
section can only be activated one at a time. The seven sections are:
•White noise generator
•2 x low frequency (500 kHz) NEXT PSD generator
•1 x high frequency (2.0 MHz) NEXT PSD generator
•Shaped noise generator
•Powerline related noise
•Metallic Noise
•Longitudinal Noise
•Impulse Noise
The output circuit is balanced with a minimum Thevenin impedance of 4000 ohms over
the range 50 Hz to 2.0 MHz.
The NSA 400 simulates a variety of impairments which can be used to test according to
the following National and International standards:
•ANSI T1.601 ISDN Basic Access Interface
•ANSI Technical Report on HDSL
•ANSI T1.413, Issue I
•ANSI T1.413, Issue II
•ANSI Proposed Working Draft for HDSL2 Standard (T1E1.4/ 98 – 268)
•ITU Standard for G.lite
•ETSI TS 102 080 ISDN Standard
•ETSI ETR 152 HDSL Standard
•ETSI ETR 328 ADSL Standard
The user can set the impairments using the IEEE or the RS-232 interface. The
command language in both cases is based on the Standard Commands for
Programmable Interfaces (SCPI) standard.
