The Power Meter is a precision digital-readout instrument capable of automatic and manual measurement of RF and Microwave power levels. It is designed for interconnection with a compatible Power Sensor (refer to Table 1-1, Specifications) to form a complete power measurement system. The frequency and power range of the system are determined by the particular Power Sensor selected for use. With the Power Sensors available, the overall frequency range of the system is 100 kHz to 18 GHz, and the overall power range is —70 to +35 dBm. 1-16. Significant operating features of the Power Meter are as follows: • Digital Display: The display is a four-digit, seven-segment LED, plus a sign when in the dBm or dB (REL) mode.
