Personal Greeting

Provides composite power readings

4043 Series, RF Power Sensors are designed for use with the 3141 Channel Power Monitor (CPM) to provide composite power readings. The sensors are typically used to measure forward and reflected average power on a 50 ohm RF transmission line with a maximum 500 watt forward and reflected power levels in a frequency band with an overall range of 118 to 940 MHz. The 4043 sensor also provides VSWR readings.

The 4043 has an RS-485 serial bus designed to transfer data to and from a CPM. The serial bus also serves as the RF sensor’s power supply. Each sensor is equipped with two RJ-25 jacks for serial communications, RF input and output connectors, and a status indicator. The second RJ-25 jack may be used to extend the RS-485 bus to another digital sensor.
