Anritsu unveils models of vector network analyser

Supplier News

Anritsu has introduced the VNA Master models MS2034A and MS2036A that offer integrated vector network analyser (VNA), spectrum analyser, and power meter capability in a single handheld, battery-operated, rugged instrument.

The VNA Master series offers the first portable handheld VNAs that can display 1-port and 2-port S-parameter measurements over the industry’s broad handheld VNA frequency coverage of 2 MHz to 6 GHz. All critical RF measurements, including S11 and S21 log magnitude, return loss, VSWR, and Distance-To-Fault (DTF), can be made with a single key selection, simplifying flightline tests, and cable and antenna maintenance.

The MS2034A/MS2036A’s RF immunity rejection of up to +17dBm allows for precise measurements, even when co-location near other transmitters usually prevents measurements due to interference.

For phase matching cables and other field maintenance tasks, the VNA Master offers a vector voltmeter option that displays results in a digital magnitude and phase format for a CW frequency. With vector voltmeters becoming obsolete, the VNA Master offers a suitable replacement that consolidates a synthesizer source, vector voltmeter receiver, and external coupling accessories. The innovative solution ensures technicians and engineers can continue to utilise this familiar display, while working with the more field-friendly VNA Master.

Incorporating spectrum analysis capability up to 7.1GHz into the VNA Master, dramatically simplifies field testing by requiring fewer instruments for maintenance activities, which is especially valuable when conducting measurements on an elevated structure, such as a tower. Users can perform common spectrum monitoring, interference analysis, and general purpose signal measurements with a single key selection, a much safer and simpler alternative to previous multiple-instrument approaches.

The MS2034A/MS2036A typical phase noise of <-110 dBc/Hz at 10 kHz offset reveals a slight spectral purity degradations in transmitters. Typical dynamic range of 100 dB allows the MS2034A/MS2036A to also accurately measure small signals, even when much larger signals are present. The wide dynamic range also allows for measurements using wider resolution bandwidths, which increases the chance of detecting intermittent signals and other sources of interference that would otherwise be impossible to troubleshoot.

MS2034A/MS2036A light weight (4 kg), three-plus hour battery life, and advanced measurement and analysis capability make it well suited for a variety of field applications. They can be used to ensure the performance of defence electronics used on naval ships, test antennas on Army vehicles, and to perform flightline tests on military and commercial jets. The high performance also allows the MS2034A/MS2036A to be used as a low-cost alternative in manufacturing and R&D.

The VNA Master features a high-resolution daylight-viewable 8.4” TFT display that allows measurement results to be seen easily in the field. An internal memory allows more than 1000 traces and set-ups to be stored. Measurement data can be transferred to computer via Ethernet, USB, or memory card. Remote programming of repetitive tasks is also possible via the Ethernet connection.
