Electronic calibration components significantly reduce calibration steps, minimize connector losses, ensure calibration accuracy, and greatlySaved calibration time and provided more opportunities for multi port testing and production line testingConvenient.

（3）Switch Matrix - Easily Achieve Multi Port Device Testing Requirements

The switch matrix can simplify the wiring for testing multi port devices and is also an important component of automatic testing systems, playing a role in controlling the flow of signals.SSM5000A series RF switch matrix, with a frequency range of 9kHz~26.5GHz, is compatible with all vector network products of Dingyang Technology. A single unit can expand the output ports to 24, and can continue to stack. Compared with traditional measurement methods, using RF switch matrix greatly improves the measurement speed, which can help engineers easily connect and test vector network analyzers and multi port test objectsAdapted to production line usage scenarios.

（4）Mechanical switch-Frequency up to 50GHz

To meet the multi-channel and multi port testing requirements of microwave and millimeter wave systems, it is recommended to useSSU5000A series mechanical switch with a frequency of up to 50GHz. Contains 1-4 independent single pole double throw mechanical switches with SMA or 2.4mm connectors, supports TTL level control, and can be widely used in multi-channel and multi port testing environments.

（5）Mixer measurement

The mixer is an important component of microwave and millimeter wave systems, and its characteristics directly affect the performance of equipment or instruments. At various stages of the development and production of mixers, it is necessary to measure their performance indicators.

Traditional vector network analyzers only have dual ports and one built-in signal source, requiring the use of an external signal source to provide local oscillator signals for measuring mixers. This not only makes the operation cumbersome, but also results in slow measurement speed and significant errors. ButThe SNA6000A series vector network analyzer has 4 ports and is equipped with two independent signal sources. It can directly measure the frequency conversion loss of the mixer without the need for an external signal source or controller.

（6）Pulse measurement function

The SNA6000A is equipped with a built-in pulse modulator and pulse generator, which are used to test high-power devices such as power transistors, as well as modules that require operation in pulse mode. The heat accumulated by continuous wave excitation may damage the device under test, while using pulse excitation for measurement can safely characterize the characteristics of such devices, while also supporting the control of external pulse generators and modulators to maintain synchronization with the external main pulse.

（7）Enhanced Time Domain Analysis (TDR) Function

SNA6000A supports advanced time-domain analysis (TDR), which can accurately measure the characteristic impedance of transmission lines and help locate the specific location of breakpoints or short circuits. In addition, the TDR function of SNA6000A can also generate eye diagrams through internal simulation, which can efficiently complete waveform consistency testing without the need for additional code generators. The use of eye diagram function can more intuitively analyze issues such as noise, jitter, and inter symbol interference in signal transmission. The TDR function can be widely used in PCB impedance testing, material performance testing, and transmission line quality testing.

4、 Specification parameters

5、 Typical applications

Frequency offset measurement can accurately evaluate the frequency conversion loss, phase, and group delay characteristics, replacing traditional complex methods. During the calibration process, a dual mixer is introduced to achieve frequency conversion between the reference path and the calibration path. The introduced dual mixer requires consistency with the frequency conversion characteristics of the tested component, and the calibration mixer requires reciprocal frequency conversion characteristics. A single connection can complete the complex characteristic measurement of the mixer/frequency converter, with high accuracy in amplitude and phase measurement.
