Summary of SIGLENT 2- AND 4-PORT 4.5/8.5GHZ VECTOR NETWORK ANALYZERS
The Siglent SNA5000A series are 2- and 4-port Vector Network Analyzers covering 9 kHz to 4.5 or 8.5 GHz with 1 Hz resolution, 125 dB dynamic range, and 0.05 dB level resolution. They measure transmission and reflection parameters (gain, insertion loss/phase, delay, group delay), scattering, differential and time-domain parameters, Q-factor and filter bandwidth. Features include five sweep types, calibration options, bias-tee support, a 12.1-inch touchscreen, HDMI output, multi-window display modes, and various measurement conveniences like fixture simulation and adapter removal/insertion adjustments.
Parts used in the Siglent SNA5000A VNA Series:
- Siglent SNA5000A Vector Network Analyzer (2- or 4-port, model dependent)
- 12.1-inch touch-screen display (integrated)
- HDMI output interface
- Bias-tee support (internal or supported accessory)
- Calibration kits or standards for Response, Enhanced Response, Full 1-4 port, and TRL calibration
- RF test ports and connectors (for DUT connections)
- Fixtures and adapters for device under test
- External display or projector (optional via HDMI)
- Power-supply and front-panel controls (integrated)
The SNA5000A VNAs bring a wide range of RF analysis capabilities for characterizing real-world passive devices, filters, and active devices with transmission and reflection measurements such as gain, insertion loss/ phase, electrical length/delay and group delay.
Saelig Company, Inc. has introduced the Siglent SNA5000A series of 2- and 4-port Vector Network Analyzers, which offer a frequency analysis range of 9kHz up to 8.5GHz with a resolution of 1Hz, a dynamic range of 125dB, and a level resolution of 0.05dB. The Siglent SNA5000A series consists of four models (2- or 4-port, 4.5GHz or 8.5GHz maximum frequency) that support measurements such as scattering, differential, and time-domain parameters, Q-factor, and filter bandwidth and insertion loss.
Vector Network Analyzers combine a signal stimulus source output and receiver inputs to measure changes to the stimulus caused by a device being tested. SNA5000A VNAs feature measurements that include impedance conversion, movement of measurement plane, limit testing, ripple test, fixture simulation, and adapter removal/insertion adjustments. Bias-tees are also supported.
The SNA5000A VNA analyzers provide five types of frequency sweep: Linear-Frequency, Log-Frequency, Power-Sweep, CW-Time, and Segment-Sweep. Operation is simplified with the VNA’s large 12.1” touch-screen display, which operates in addition to traditional front-panel controls. An HDMI output is also provided so that an even larger display or projector may be used. Many useful display modes may be selected, such as: multi-window, multi-format, display hold, memory comparison, and impedance conversion. Calibration choices include: Response calibration, Enhanced Response calibration, Full-one port calibration, Full-two port calibration, Full-three port calibration, Full-four port calibration, and TRL calibration.
