Informatie
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. It also has under- and
