Anritsu Co. has introduced the ML2480B series wideband peak power meters that combine wide 20MHz bandwidth and 64MS/s sampling rate that allow the instruments to conduct highly accurate peak power measurements on next-generation wireless and military communications signals.

The new power meters provide best-in-class performance and ease of use, which make them well suited for evaluating chipsets, modules, handsets, customer premise equipment (CPE), and base stations during R&D and manufacturing.

There are two power meters in the series, both of which are designed to measure average power, peak power, and crest factor, as well as provide statistical analysis of complex modulated signals. The ML2487B supports single sensor input while the ML2488B supports dual sensors inputs. The dual-channel sensor input and display of the ML2488B allow for the simultaneous monitoring of WLAN and Bluetooth –enabled devices, and provides critical testing for the co-existence of multiple standards. The wide video bandwidth enables high accuracy peak power measurements on the most demanding power envelope conditions.

The ML2480B series includes an Ethernet remote control interface, preset of 18 popular predefined and configurable measurements, and an external video port that supports LCD and CRT monitors for easier viewing of results. The incorporation of the Ethernet interface makes it easy to integrate the power meters into PC-centric ATE racks that need to be controlled remotely via a LAN.

Further simplifying operation is a remote graphical user interface, PowerMax, which provides a visualisation of instrument display and streamlines remote control of the ML2480B. PowerMax allows measurement results for up to eight gates and up to four marker readings to be simultaneously displayed on a monitor. The software also creates configuration tabs so that the instruments can be easily controlled directly from a PC. Measurement result images and traces can be saved directly on a computer's hard drive or removable storage, allowing raw data to be recalled and used as reference.

Six families of CW, average, wideband, pulse and thermal power sensors to 50GHz cover a wide range of measurement applications are compatible with the ML2480B series.

The ML2487B and the ML2488B delivery is 4 weeks ARO.
