EXT METER
Applications
External leveling can be used when your application requires long cables
that will cause frequency-dependent losses . It also enables devices , such as
ampliers , mixers , etc. to be inserted into the RF signal path so that the
output of the inserted device is controlled by the synthesizer .
External Equipment Limitations
P ower Meter The power meter must be capable of producing a 0 V to 1 V output voltage
linearly proportional to power over each decade of range . The recorder
output of most power meters provides this voltage .
P ower Sensor The power sensor must have a frequency range that is appropriate for the
range of frequencies being leveled. The sensor must also have enough
dynamic range to measure the level at the output of the directional coupler or
power splitter . As an example , to level signals in the 07 dBm to 0 dBm range
using a 10 dB coupler , the power sensor must be capable of measuring power
in the 017 to 010 dBm range .
