Thank you very much for purchasing the Array Solutions PowerMaster Series RF Power/VSWR Indicator. The PowerMaster represents a breakthrough in features for measurement of the performance of your transmitting system. Microprocessor control insures fast capture time and low power consumption. With the ability to monitor your VSWR and power levels at all times, you will know that your transmitter, RF source, and load, or antenna systems are operating effectively and safely. In addition, the power and VSWR relay alarms can quickly shut down your power amplifier system and alert you to the alarm condition. This places an additional layer of protection in your transmitting system to help preserve expensive tubes and finals. The PowerMaster also features the ability to be monitored and controlled from a PC via the bundled software, and the unique ability to be monitored and controlled over a LAN or from the internet. PowerMaster firmware updates will be made available for download from the Array Solutions website as they becomeavailable. This means that the user can take full advantage of features or enhancements just by installing the firmware update. No need to return the meter to the factory for updates.
