Description: RF POWER SENSOR

The 6900 Series of RF Power Sensors is used with 1FR 6960 Series RF Power Meter, the 6970 RF Power Meter, the CPM 20 and CPM 46 Counter Power Meter and the 6200 Series of Microwave Test Sets. Note, however, that the 6930 Series of sensors can be used with the 6960A and 6960B RF Power Meters, but cannot be used with the 6960 RF Power Meter. The sensors provide the meter with a chopped DC analogue of the RF power, and collectively they cover a power range from -70 dBm to +44 dBm (0.1 nW to 25 W) at frequencies from 30 kHz to 46 GHz- Each Sensor has an individual label showing a graph of 'calibration factor', and values of ’50 MHz reference calibration factor' and 'linearity factor'. The calibration factor appropriate to the measurement frequency and the linearity factor may be entered into the instrument to enhance accuracy. The 6200 Series of Microwave Test Sets allow entry and storage of all the calibration data supplied with the sensors. A 'calibration record' giving linearity factor and calibration data to two decimal places is also provided with each Sensor. VSWR and uncertainty values are low' across die entire frequency range of the Sensor. Each Sensor has a multi-way output connector for connection to the power meter via the Sensor cable that is supplied with the meter. The Sensor provides high level signals to the power meter so that the possibility of significant RF interference during measurements is negligible. A high damage level threshold minimizes the possibility of damage to the RF unit. Damaged units are, however, field replaceable in most cases (see Chapter 5). Its small, light, rugged construction allows the Sensor to be used confidently in bench or field applications without the need for any mechanical support.
