PCM Channel Analyzer XG2038

Features: PCM Channel Analyzer is an advanced portable PCM test instrument developed on the basis of multi-task operation system. Not only can it perform characteristics testing on full voice channel and half voice channel, but also provide E1 BER measurement. It is widely used to check PCM devices, digital switches, carrier wave communication devices, VoIP devices and etc, and especially applicable in the testing of R& D, production, engineering installation, commissioning, and maintenance. Functions: ? A-A Voice channel characteristics testing: Level, Variation of gain with frequency, Variation of gain with input level, Total distortion including quantizing distortion, Idle channel noise, Crosstalk, Return loss, Longitudinal conversion loss, Longitudinal conversion transfer loss ? A-D, D-A, D-D Voice channel characteristics testing ( option) : Level, Variation of gain with frequency, Variation of gain with input level, Total distortion including quantizing distortion, Idle channel noise, Crosstalk ? 2M ( E1) frame and unframed BER testing, alarm detection and error analysis ( Option) ? Call set-up: support on-hook, off-hook, dialing, ringing, and ringing supervise ? Auto and manual mode available ? Built-in balanced bridge and reflecting bridge, Return loss, Longitudinal conversion loss and Longitudinal conversion transfer loss can be measured by one tester ? Built-in call set-up circuit can set up testing channel directly by dialing on the tester without the help of other telephone ? Support test of frequency spots sequence of equal step and customized frequency spots, and the number of spots is optional ? Built-in generator and receiver, analog input and output interfaces are separately with ICT and OGT. Interfaces can be directly tested, including 2/ 4W E& M, MDR, LGE, FXO, LGS and FXS ? Provide direct testing of voice channel indexes on unbalanced audio interface ? Results are shown graphically, and can be compared with the built-in reference mask to evaluate whether it passes or fails ? Built-in test mode can be defined by clients, efficiently satisfying testing standard definition of different products ? Remote control signaling group is available, so as to secondarily develop under different conditions by clients ? Results can be uploaded to PC over USB or LAN port, so as to be analyzed, assembled, filed and printed via software ? Embedded software can be upgraded for free and protect the client? s investment Specifications: Analog generator/ receiver: 1. Frequency: 200Hz ~ 3600Hz 2.
