PNA3621 Vector Network Analyzer


Full frequency scan, list scan and point frequency measurement available.
Capable for transmission measurement (measurement of amplitude vs. frequency characteristics, insertion loss, phase shift, amplifier gain, antenna gain, group delay, antenna azimuth pattern optional), reflection measurement (measure SWR, R.L., complex impedance, reflection phase, electrical length, and Smith Chart display function), time domain fault location function (TDR).
Transmission measurement has either logarithm-amplitude display or amplitude-phase display; Reflection measurement has LOG display, SWR display, and Smith Chart display.
5.0” liquid colour display (LCD), serial port output to PC displays, built-in micro printer
Application scope and relational properties:
l   Widely used in the antenna-feed system test and measure installations of FM, TV, CATV, communications, RADAR etc, and also for the RF microwave education laboratory in the university.
l   Optional matched, for 50Ω, 75Ω, 100Ωetc, different characteristic impedance systems.
l   Time domain fault location function. It is able to locate a fault in a coaxial cable, with its range: 0-1200 meterprecisely located, a thousandth of full scale
l   Configure the correspondingtest accessories (impedance converter and differential bridge…) so as to satisfy the coaxial cable, twin-twist cable, coaxial connector, etc ,the characteristic impedance of transmission lines, loss, delay, phase shift parameters such as test, and is able to detect leakage of RF cables and shield performance.
l   Select and prepare corresponding probes capability for the ε measure of such material as the liquids, plane solids, powder, fabric etc.
