The Rohde & Schwarz NAS Directional Power Meter is a portable, battery-operated instrument designed for measuring the power and standing wave ratio (SWR) of all kinds of radio equipment in the field. It accepts a range of interchangeable insertion units to cover different frequency bands and power levels, including mobile radio applications and digital networks to the GSM standard.
The meter simultaneously displays forward and reflected power, or alternatively forward power and SWR, giving engineers a comprehensive view of RF system performance without additional instrumentation. Its straightforward interface and automated features make it well suited to both installation and maintenance tasks.
