RI 900 Radar Performance Monitor  

Data sheet

The Ranatec RI 900 is the 4th generation radar performance monitor from Ranatec Instrument AB / Magnetic AB. It is fully backwards compatible with its predecessor RM9000 and adds new features and higher performance. It also replaces the obsolete MT7300 series (MT7310, MT7320, MT7321, MT7360, MT7370, MT7371) system noise monitors from Maury Microwave.

Radar Performance Monitor

Model 9000  

Data sheet

The Monitor Series 9000 is designed to monitor the RF performance of a radar system. It offers the capability of continuously monitoring the Average Output Power, Average Reflected Power (antenna VSWR) and Noise Figure without interfering with the normal operation of the radar.

Due to the modular design, a choice of up to four power measurements and up to four noise figure measurements can be performed simultaneously in one instrument. The trigger input provides synchronization of the monitor timing circuits with the radar Tx pulse.

The Monitor Series 9000 displays the measured parameters on a 4 by 20 character display and compares the measured values with user-set alarm levels. For each measured value an individual alarm level can be set.

The instrument can be operated either with the front panel keypad or remotely via RS232C, LAN or GPIB (IEEE-488) interface. The Monitor information can be used to automatically switch over from a faulty to a standby Tx/Rx unit or to detect deterioration and ageing before a critical condition occurs.

To enhance the absolute measurement accuracy, Monitor 9000 incorporates a feature which allows the operator to store correction values which compensate for sensor tolerances. Calibration tables are attached to each sensor and directional coupler for this purpose.

Note that the Monitor 9000 is fully compatible with all previous Monitor models made by Ranatec Instrument AB and Magnetic AB for plug in replacement.
