MORGAN HILL, USA: Anritsu Co. has introduced the MS202xB/MS203xB VNA Master series, the highest-performing handheld RF vector network analyzers (VNAs) in the industry.
With frequency coverage from 500 kHz to 4/6 GHz, and featuring multi-instrument functionality in a rugged, lightweight design that can withstand harsh environments, the MS202xB/MS203xB allow field engineers to find faults, optimize mission-critical systems, and maintain more sites while reducing operating and capital equipment expenditures.
VNA Master provides field engineers with a powerful S-parameter measurement tool for on-site installation and maintenance activities, especially two-port transmission measurements such as filter tuning, component test, and phase matching cables.
Versatile, the VNA Master is also an all-in-one tool that can replace laboratory grade instruments, such as scalar analyzers, vector voltmeters, power meters and spectrum analyzers, in the field. In fact, the VNA Master is the highest-performing RF handheld tool for filter tuning based on its fast display updates of 850 usec/point and typical dynamic range of 100 dB.
The MS202xB/MS203xB VNA Master series is designed with a 2-port vector network analyzer architecture that provides S11 and S21 measurements that are generally 10 times more accurate than scalar measurement approaches found in other economy handheld tools.
For example, the VNA Master can measure filter passband insertion loss (i.e., S21) with better than 0.1 dB precision; a scalar approach is on the order of 1.0 dB precision. This difference is critical when measuring signal separation components, in which loss, flatness, and rejection translate into less site coverage, less compliance with the allocated spectrum, or more vulnerability to interference issues.
The improved dynamic range, coupled with selectable IF Bandwidths between 10 Hz and 100 kHz, offers flexibility to configure S-parameter measurements for maximum display updates or maximum accuracy.
Additionally, the VNA Master analyzers have 1 Hz frequency resolution for enhanced measurements of out-of-band filter characteristics. Selection of up to 4001 data points offers hands-free operation when measuring longer cables or verifying filter characteristics. New polar and impedance graphs offer additional flexibility to cable, filter, and antenna readouts.
