The XG2038 is a world-class portable overall measuring instrument with many testing functions for PCM channel characteristics (both full-channel and half-channel), and error testing for E1 as well, based on multi-task OS of Win CE.
It can be used to measure PCM device, digital switch, carrier wave communication device, client＇s dispatching equipment, digital broadcasting station with voice channel interface and VoIP device, especially applicable to science research, manufacturing, engineering installation, check and acceptance as well as maintenance.
1. Basic Functions
- Voice channel Characteristics testing
√ A-A: 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: 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
- Call set-up: support on-hook, off-hook, dialing, ringing, and ringing supervise
- Auto and manual mode available, on the auto mode, all or one or several of the above performance characteristics can be selected to measure
- Support test of frequency spots sequence of equal step and customized frequency spots, and the number of spots is optional
- Support selective frequency measuring on all frequency spot
- Results are shown graphically, and can be compared with the built-in reference module to evaluate whether it passes or fails
- Perfect indication of working state and alarm
- Large storage capacity of results and measuring configurations, up to 100 groups
- Available in remote control via USB and Ethernet interface, to meet the need of different control modes
- Results can be uploaded to PC, so as to be analyzed, assembled, filed and printed via TestManager Pro software
2. Main Features
- Overall functions, satisfy users’ measuring requirements
- Integrated with tone oscillator, Selective Frequency Meter, BER tester and Call Generation, more PCM channel characteristics can be measured one time
- 5.7 inches 640X480 high-resolution colorful LCD display
- Flexible control modes, supporting touch operation, key-stroke operation and expanded mouse operation
- Convenient Windows style, easy to operate
- Built-in call set-up circuit, can set up testing channel directly by dialing on the tester without the help of other telephone
- 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
- 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 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
- Embedded software can be upgraded online and protect the client’s investment
