The XG2028 Datacom Transmission Analyzer is a low-cost handheld instrument. It is widely used to identify and verify quality-of-service of datacom (V.24, V.35, V.36, X.21, RS-449, RS-485, EIA-530 and EIA-530A) transmission channels in Access Network, Transmission Network, Digital Data Network (DDN) and some private communication networks. XG2028 is intended to meet the demands of R&D, production, equipment installation, check and approval, daily maintenance and service verification.
Basic Functions
- Bit error test of DATACOM (V family, X family, RS family, EIA family) interfaces.
- DATACOM (V.24, V.35, V.36, X.21, RS-449, RS-485, EIA-530 and EIA-530A) interfaces can be configured with DTE or DCE, ASYNC or SYNC mode.
- Monitor and control handshaking signals.
- BAUD Rate: 50b/s~38.4Kb/s, N×64Kbit/s (N=1~32).
- In SYNC test mode, Rx and Tx clock sources are selectable with internal or external and rising or falling edge sense.
- Error injection: Single, Fixed Rate, OFF.
- Measurements of errored blocks and clock slips.
- Real-time Clock.
- Performance analysis in accordance with ITU-T G.821.
- 12 LEDs alarm and status indicators.
- The test results can be uploaded to PC via the serial port. And TestManager™ software could do further analysis, assembling, filing, and report outputting of the test results.
- On-line embedded software upgrading.
Main Features
- Handheld structure, durable design, suitable for carrying around and on-spot measurements.
- High resolution backlight LCD, smart navigation mode operation displays in English.
- Synchronization performance measurements give references to the more and more important system synchronization problem.
- Perfect alarm detections and indications.
- Up to 99 days continuance test performance.
- Built-in NiMH rechargeable batteries and embedded with smart fast charger circuit.
- Can be charged with automobile cigarette lighter battery adapter.
- High storages capacity, can store 4 groups of test results including settings and results information.
- Real-time clock and storages could be kept during a long time by power supply of the second spare battery without AC adapter and built-in NiMH battery module.
- By using TestManager software, upgrading the embedded software of the instruments via the serial port to perfect the functionalities of the instrument and protect your investment.
