Normalization measurement of tracking generator
Normalization measurement reduces the cable loss during the measurement process. It can reflect the
amplitude-frequency characteristic of tested object in a more accurate way. For example of testing the
amplitude-frequency characteristic of 2.3 GHz~2.4 GHz band-pass filter, refer to the following steps:
a) Press
【
Freq
】→
[Start Freq], and set the start frequency to 2.1 GHz;
b) Press
【
Freq
】→
[Stop Freq], and set the start frequency to 2.5 GHz;
c) Press
