Siglent launches handheld VNA
Siglent has launched a handheld vector network analyzer (VNA)
The Siglent SHN900A is available with a frequency as high as 26.5GHz and integrates vector network analysis, spectrum analysis, cable and antenna test and time domain analysis in one portable device.
The handheld VNA is powered by Li-ion batteries with an endurance of up to 4 hours for “Out-of-lab”-measurements. The main areas of applications are installation, maintenance and service of communication systems in the field as well as maintenance for production lines and field tests at automotive electronics.
- Real time spectrum analyzer adds VNA as standard .
- Software-defined handheld analyzer meets emerging test requirements
The VNA has a dynamic range of up to 110 dB and low trace noise of 0.0005 dB rms, 0.015 deg rms that improves the test accuracy and meets the user’s need for precise measurement. It supports the measurement of S-parameters (S11, S12, S21, S22) as well as the differential S-parameters (Sdd11, Sdc11, Scd11, Scc11), and supports all standard display formats such as Smith Chart, Polar Chart, SWR, etc.
The high dynamic, the low noise and the flexible measurement and display settings on the 8.4in touchscreen on the 3.2kg unit help the test engineer to get reliable data.
The accuracy of every network analyzer is closely related to calibration. SHN900A supports calibration methods such as SOLT, SOLR, TRL, Response, Enhanced Response, etc. It is compatible with a variety of calibration sets, supports user-defined calibration kits for testing devices with different interface types as well as impedance conversion, fixture simulation and adapter removal/insertion.
The Cable and Antenna Test (CAT) mode of the SHN900A assesses and diagnoses the electrical performance of RF and microwave transmission systems. It is well-suited for tasks like installing and maintaining antenna systems, conducting distance-to-fault (DTF) measurements on cables, measuring single-port cable loss, and assessing antenna matching. The SHN900A also includes a built-in GPS function for providing geographical positioning during measurements. Its bias tee feature conveniently supplies DC bias to external objects being measured. Capabilities such as segmented sweep and frequency offset mode enhance analysis precision, efficiency, and flexibility for components testing.
The spectrum analysis mode facilitates measurement of parameters like channel power, adjacent channel power ratio (ACPR), and occupied bandwidth. This enables the technician in the field to verify RF signals and make sure all is in specification.
The Marker → SA function allows a quick change from VNA to spectrum analyzer mode and look at the specific marker frequency point in both modes. A convenient way streamlining signal search and analysis. Time Domain Analysis (TDA) supports various functions such as time-domain transformation, windowing, and gating, aiding in device characterization from both time and frequency domain perspectives. Time Domain Reflectometry (TDR) offers many enhancements compared to TDA. This include reflection and transmission analysis, eye diagram simulation, also allowing swift fault localization and type determination, along with simulated eye diagram generation and jitter injection for assessing signal transmission effects.
Quick-access buttons and an intuitive setup structure streamline testing procedures, facilitating swift, error-free standardized measurements. Engineers can easily manage windows, channels, and traces, enhancing usability and meeting diverse test needs efficiently.
