Siglent 2- and 4-Port 4.5/8.5GHz Vector Network Analyzers

Siglent 2- and 4-Port 4.5/8.5GHz Vector Network Analyzers


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.

LAN and USB interfaces are provided (USB-GPIB optional) to allow remote control via SCPI/Labview/IVI/VXI-11/Socket/Telnet/WebServer, etc.
