the RF signal generator usually contains a calibrated attenuator
and an output level meter. The output level meter provides an
indication and permits control of the output voltage of the
generator. The attenuator allows you to select the amount of
this output. The attenuator is made up of a group of resistors
that form a voltage-dropping circuit. It is controlled by a
control calibrated in microvolts. When the control is adjusted
so that the output meter reads unity (1.0), the reading on the
attenuator control gives the exact value (no multiplication
factor) of the output in microvolts. If an output voltage at a
lower value is desired, the
