Main Application Scenarios
| The inherent structural complexity of indoor distributed networks often renders existing testing methods ineffective, a phenomenon even more pronounced in 4G/5G system detection and maintenance. Common reasons include: |
| A. 4G/5G employs intelligent transmit power control, resulting in significant power fluctuations in the link, causing difficulties in power verification during system acceptance testing; |
| B. The power changes significantly from the transmitter (e.g., RRU) output to the antenna end. Typical systems involve changes from watts to milliwatts, and in case of failure, it may even drop below milliwatts. Existing power meters can only measure tens of milliwatts, and although terminal power meters have a wider dynamic range, they cannot perform real-time online measurements; |
| C. Due to the numerous link values, it is impossible to use an antenna and feeder testing instrument for fault location or component detection during troubleshooting; |
| D. 4G LET-TDD/5G uses an uplink and downlink co-frequency output mode. When the link exhibits an imbalance between uplink and downlink, spectrum analyzers or field strength meters cannot distinguish the transmission direction of the measured signal; |
| E. 4G/5G occupies multiple frequency bands with wide frequency band coverage (1800~2700MHz). When intermodulation interference occurs in the link, although a three-order intermodulation instrument can be used for testing, it is usually only suitable for a single frequency band and cannot cover the entire network bandwidth. |
Shenzhen Tongqi Communication's indoor distributed test kit is a pioneering, complete radio frequency measurement system. This system not only solves many challenging indoor distributed network testing problems, but also boasts simplicity, flexibility, and efficiency.
Product Suit Features
| TQ-1200A | |
 | Dual-ended, highly stable adjustable output Provides highly stable output, with main output power up to 31dBm, minimum -10dBm, high spectral purity, especially suitable for monitoring various amplification and transmission links. |
Dual ultra-wideband design, preset frequency points Continuously adjustable from 300MHz to 3000MHz, covering most mobile communication frequency bands. 10 commonly used test frequency bands are preset, common frequency points can be set according to user requirements, and frequencies can be customized. | |
High-efficiency testing, scanning testing No warm-up or calibration process is required. Compared with other terminal equipment (such as network analyzers, antenna test instruments, etc.), the test time is greatly shortened, and it supports uninterrupted emission of stable signals at different frequencies to assist testing. | |
| TQ-3200A (Left) / TQ-3200B (Right) | |
 | Ultra-high dynamic range The combined power measurement range is up to 70dB (-20dBm~+50dBm), with an overlapping range of up to 20dB |
High-precision measurement Through calibration of specific frequency bands, and optimization of return loss and directivity, etc., the accuracy of power measurement is ensured in multiple aspects. | |
Dynamic power correction When checking or spot-checking link power, power simulation can be performed at any time for different transmitters or remote units (RU). | |
Long-term online monitoring When the transmitting system encounters soft faults such as power jitter or drift, fault location can be achieved through online detection and data analysis over a period of time. This is currently the only through-type power meter that can achieve completely independent long-term online detection without relying on any other equipment or instruments. | |
High-reliability design In case of input-output misconnection during use, it will not be damaged, but will prompt through the display screen and audio signal. Even permanent misconnection will not damage the instrument. | |
Intelligent The instrument automatically enters the test state with only the correct frequency band information. During the test, the display mode can be switched at will, and various parameters can be monitored in real time. | |
| TQ-3400A | |
 | Full-band scan It can identify which frequency band signals are mixed in a mixed signal of 2G/3G/4G. The instrument's default frequency range and name can be customized. |
Clear and concise power values Visual interface, connecting the tested feeder line can immediately know the current forward power value, and classify according to frequency, the power value results are clear, easy to understand, and the equipment operation is simple and intuitive. | |
Optimized design for indoor distributed systems It can accurately locate frequency band faults, especially for the wireless small signal test function of the uplink channel. It is suitable for the construction and maintenance of communication fields such as telecommunications, broadcasting, railways, power, and military, as well as teaching and research in scientific research institutes. | |
