Description

Technical Field

[0001] The utility model relates to the technical field of communication equipment, in particular to a communication test instrument. Background Art

[0002] Communications test instruments are tools designed specifically to test and evaluate various communications performance characteristics. With the rapid advancement of information technology, these instruments play a vital role in ensuring the reliability, efficiency, and security of data transmission. They accurately measure key parameters such as signal strength, frequency response, and signal-to-noise ratio, helping engineers diagnose problems, optimize system configurations, and maintain network quality. Communications test instruments are indispensable tools in a variety of fields, including mobile communications, internet services, and satellite communications. These highly specialized instruments can significantly improve communication efficiency, reduce downtime, and ensure smooth information exchange.

[0003] like Figure 1 As shown, the design of communications test instruments is increasingly trending towards complexity and versatility to accommodate a wide range of application requirements. These devices typically integrate RF and high-speed digital interfaces to support a wide range of communication protocols and high-speed data transmission. Designing such equipment often requires the use of PCBs (printed circuit boards) with 10-20 or even more layers to lay out complex circuits and ensure proper interface routing. Furthermore, matching and interference mitigation must be considered during the design. The aforementioned design methods can effectively mitigate signal interference and transmission loss, ensuring device performance and reliability.

[0004] To further ensure signal integrity, power integrity, and high performance of RF circuits, designers often use high-end PCB materials, such as the Rogers series. These high-performance materials offer lower dielectric constants and loss factors, facilitating the transmission of high-frequency signals. However, these advantages come at a higher cost. High-level (i.e., multi-layer) PCB designs not only increase the complexity of the manufacturing process but also require the use of expensive specialty materials. While device performance has significantly improved with technological advancements, this high level of specialization and increased material costs have also had a significant impact on product pricing. Manufacturers and designers face the challenge of optimizing design, reducing costs, and maintaining performance, which is directly related to the market competitiveness and widespread availability of the final product.

[0005] Due to the diverse and complex external interfaces of instrumentation, an increase in PCB design area is inevitable. These devices need to accommodate multiple RF and high-speed digital interfaces, as well as the complex signal processing circuitry that supports them. This requires ample space to arrange these components and circuits. This increased design area not only increases the amount of board material used, but also increases the precision and process complexity required during the manufacturing process, further driving up production costs. Therefore, while technological advances have brought improved performance, they have also led to significant cost increases, placing additional financial pressure on the design and manufacture of instrumentation.

[0006] In summary, traditional communication test instruments have the following technical problems:

[0007] Cost issues: The use of high-level PCBs and specialty boards such as Rogers in the design of instruments and meters has led to a significant increase in production costs, increasing the price of the final product and potentially limiting its widespread market acceptance;

[0008] Design complexity: To meet the requirements of high performance and multi-functions, complex circuit design leads to extremely complex PCB design for instruments and meters, which not only increases the design difficulty, but also increases the complexity and error rate of the manufacturing process;

[0009] Increased design area: To accommodate diverse and complex interface requirements, the design area of ​​PCB circuit boards inevitably increases, which directly leads to increased material usage and higher production costs, and may also affect the portability and flexibility of the device.

[0010] Signal coupling issues: In traditional PCB layouts, when multiple high-speed signal lines are routed in parallel, signal quality is often compromised due to electromagnetic interference and crosstalk. This coupling not only degrades signal integrity but can also lead to data transmission errors and system instability.

[0011] Difficulty in updating and maintaining: Due to the high design complexity of instruments, it becomes more difficult and expensive to update or maintain these devices once market or technical requirements change. In this case, the adaptability and long-term usability of the equipment may be limited, increasing the potential cost to users during use.

[0012] It can be seen that traditional communication test instruments have technical problems such as high cost, high design complexity, large design area, poor signal quality and difficult updating and maintenance. Utility Model Content

The design structure is simple, and updating and maintenance are simpler, and the manufacturing cost of the communication test instrument is reduced, alleviating the technical problems of traditional communication test instruments such as high cost, high design complexity, large design area, poor signal quality and difficult updating and maintenance.

[0035] Traditional communication test instruments are costly, complex in design, require large design areas, have poor signal quality, and are difficult to update and maintain.

[0036] Based on this, in the communication test instrument of the present invention, unlike the traditional external interface that is directly set on the PCB and the connection circuit between the external interface and the test control unit is also set on the PCB, the external interface of the communication test instrument of the present invention is set on the panel of the communication test instrument, and the external interface and the test control unit are connected by a cable, which reduces the area size of the PCB, makes it more compact, and is easy to integrate and carry, improves the flexibility of the equipment, and also reduces the loss and interference during signal transmission. Because when the signal is transmitted through the cable, since each signal line is wrapped by its outer layer of shielding, the isolation between the signals is better, which improves the communication test instrument's resistance to external electromagnetic interference, thereby improving its test performance and working reliability. The design structure is simple, updating and maintenance are simpler, and the manufacturing cost of the communication test instrument is reduced.

[0037] To facilitate understanding of this embodiment, a communication test instrument disclosed in an embodiment of the present utility model is first introduced in detail.

The test control unit is used to control the workflow of the communication test instrument and analyze and process signals. It can be seen from the above description that in the communication test instrument of the present invention, unlike the traditional external interface that is directly arranged on the PCB and the connection circuit between the external interface and the test control unit is also arranged on the PCB, the external interface of the communication test instrument of the present invention is arranged on the panel of the communication test instrument, and the external interface and the test control unit are connected by a cable, which reduces the area size of the PCB, is more compact, easy to integrate and carry, improves the flexibility of the equipment, and also reduces the loss and interference during signal transmission. Because when the signal is transmitted through the cable, each signal line is wrapped by its outer layer of shielding, so the isolation between the signals is better, the communication test instrument's resistance to external electromagnetic interference is improved, and thus its test performance and working reliability are improved. The design structure is simple, and updating and maintenance are simpler, and the manufacturing cost of the communication test instrument is reduced, alleviating the technical problems of traditional communication test instruments such as high cost, high design complexity, large design area, poor signal quality and difficult updating and maintenance.

[0043] The above content briefly introduces the communication test instrument of the present invention. The specific contents involved are described in detail below.

[0044] In an optional embodiment of the present utility model, the communication test instrument further includes: a functional unit provided on the PCB;

[0045] The functional unit is connected to the test control unit and is used to realize various functions required for the communication test instrument to work.

[0046] Specifically, the above functions include but are not limited to data processing, data storage, reset, clock control, etc.

[0047] In an optional embodiment of the present utility model, the communication test instrument further includes: a power supply unit;

[0048] The power supply unit is connected to the test control unit and the functional unit respectively, and is used to supply power to the test control unit and the functional unit.

[0049] Specifically, the power supply unit may be provided on the PCB or may be provided separately.

[0050] In an optional embodiment of the present invention, the external interface includes: a radio frequency interface and a high-speed digital interface.

[0051] In an optional embodiment of the present invention, the cables include: a radio frequency cable and a high-speed cable;

[0052] One end of the radio frequency cable is connected to the connector via a high-speed connector, and the other end of the radio frequency cable is connected to the radio frequency interface;

[0053] One end of the high-speed cable is connected to the connector via a high-speed connector, and the other end of the high-speed cable is connected to the high-speed digital interface.

[0054] Specifically, the radio frequency cable may be a coaxial radio frequency cable, and the high-speed cable may be a dual-core high-speed cable.

[0055] In an optional embodiment of the present invention, the components provided on the PCB are compactly and centrally arranged.

[0056] Specifically, in order to miniaturize the communication test instrument, the components (ie, structures / units) provided on the PCB board can be compactly arranged and centrally arranged to reduce the size of the PCB and the overall size of the instrument.

[0057] In an optional embodiment of the present invention, the distance between the test control unit and the joint is less than a threshold distance.

[0058] Specifically, the distance between the connector and the test control unit should be as short as possible, so the distance between the test control unit and the connector is less than a threshold distance, thereby reducing signal delay and interference, and improving transmission efficiency and instrument performance.

[0059] In an optional embodiment of the present utility model, the communication test instrument further includes: a display unit and a wireless connection unit;

[0060] The display unit is connected to the test control unit, and the wireless connection unit is connected to the test control unit.

[0061] In conventional technology, the external interface of a communication test instrument is usually directly arranged on a PCB, and the connection circuit between the external interface and the test control unit is also arranged on the PCB, which leads to the aforementioned shortcomings. The present invention adopts a cable to replace this part of the PCB connection circuit, and leads the signal to the instrument port (i.e., the external interface) through the cable, which not only reduces the size of the PCB, but also reduces the loss and interference during the signal transmission process (compared to the PCB connection circuit, when transmitting signals through the cable, since each signal line is wrapped by the shielding of its outer layer, the isolation between the signals is better). In addition, the manufacturing cost of the communication test instrument is also reduced, and its test performance and working reliability are improved (the high degree of signal isolation helps to improve the resistance of the communication test instrument to external electromagnetic interference, ensuring stable operation in complex electromagnetic environments). The reduction in PCB size also makes the communication test instrument more compact, convenient for integration and carrying, and improves the flexibility and application range of the equipment.
