9.2. Determination of amplitude-frequency response
Attention! If the output power of the measured device is not known, always set the maximum
value of the internal attenuator of the device!
9.2.1. In the
Generator
menu, turn on the
Tracking
mode and set the value of the
Generator Power
in the range from -15 to -25 dBm, depending on the equipment under study. Set the desired attenuation
level of the input attenuator
Input attenuator
in the range from 0 to -30 dB, figure 69.
igure 69 Setting the signal attenuation level by the input attenuator
Attention! The use of small values of the input attenuator requires special attention, since a
signal exceeding 10 dBm can damage the input circuit of the device!
Note. Use external attenuators if necessary.
