Dingyang Technology Releases SNA5000X Series Vector Network Analyzers
On December 18, 2020, Dingyang Technology officially released the SNA5000X series vector network analyzer (Vector Network Analyzer), its measurement frequency is up to 8.5GHz, supports 4-port S-parameter measurement, differential (balanced) measurement, time domain measurement, filter One-key measurement of insertion loss, bandwidth, Q value, etc., support port impedance conversion, port expansion function, support limit test, ripple test function, support fixture simulation and de-embedding function, support linear frequency sweep, logarithmic frequency sweep, segment Frequency sweep, linear power sweep, support SOLT, SOLR, TRL, Response, Enhanced Response and other calibration methods, can be widely used in filter, duplexer, antenna, active device, RF cable and other fields of research and development, production and manufacturing .
Low noise, high dynamic range
System dynamic range is a very important indicator of VNA, which is the difference between the maximum output power of the VNA source and the noise floor of the test port. The dynamic range of the SNA5000X can reach [email protected] IFBW, and the receiver noise floor is -125 dBm/Hz. It is suitable for test scenarios with high dynamic range requirements, such as measuring the passband and out-of-band rejection performance of filters at the same time.
S-parameter test/balanced-unbalanced test
The SNA5000X series supports adding multiple traces in multiple windows for full 4-port S-parameter testing, and has multiple Display formats, such as Log Mag, Lin Mag, Smith, Phase, Delay, Smith, SWR, Polar, etc., which can be convenient and fast Analyze the transmission coefficient, reflection coefficient, standing wave ratio, impedance matching, phase, delay and other parameters of the measured object. When verifying the characteristics of antennas, filters, etc. in the production line, you can also save reference traces or add Limit templates for pass-fail testing, which is beneficial to improve production efficiency.
The SNA5000X series also supports the port impedance transformation function. For example, when testing active differential amplifiers, the input and output ports can be impedance transformed to perform differential (balanced) measurements (such as Scc, Sdd, Scd, Sdc and other parameters). This feature can also be applied to other differential class tests such as differential cables.
Time domain analysis function and eye diagram function
In the microwave RF field, how to effectively eliminate harmful test fixture effects is a major challenge. For example, when testing SMD devices, a specific test fixture is required to realize the connection between the test end of the test instrument and the input end of the device, resulting in the test results including the characteristics of the test fixture. At present, the methods provided by the SNA5000X series to remove the influence of test fixtures mainly include: port extension, port matching, port impedance conversion, de-embedding, adapter removal, etc.
In addition, the SNA5000X series also supports the TDR time domain reflectometer measurement function, which can analyze the characteristic impedance, delay and other parameters of the transmission line in the time domain.
The eye diagram can reflect the overall characteristics of the digital signal transmitted on the signal chain, from which the influence of inter-symbol crosstalk and noise can be observed, and then the degree of pros and cons of the system can be estimated. Therefore, eye diagram analysis is at the heart of signal integrity analysis of high-speed systems. The SNA5000X is equipped with an eye diagram function, which saves a lot of cost and time for customers who need to perform time domain analysis on high-speed signals.
Calibration piece
Calibration is a necessary step before a VNA can make reliable measurements. Dingyang Technology can currently provide 8 kinds of SOLT mechanical calibration parts, which are divided into economical calibration parts and precision calibration parts. The calibration frequency range covers DC~9GHz, and the interface types include SMA and N type. In addition, the SNA5000X series can also support the import of calibration parts from other manufacturers and customer-defined calibration parts, so as to protect customers’ investment in calibration parts.
SNA5000X series includes SNA5052X, SNA5082X, SNA5054X, SNA5084X a total of 4 models, the measurement frequency range covers 9kHz~4.5GHz/8.5GHz, supports 2-port and 4-port S-parameter measurement, has a 12.1-inch touch screen, supports external mouse and keyboard operation, and has a friendly human-computer interface. Compared with traditional vector network analyzers, it is smaller in size and lighter in weight, saving customers a lot of laboratory and production line space. With its rich functions and excellent interactive experience, SNA5000X series vector network analyzers are widely used in company R&D, manufacturing, research institutes and other scenarios.
