OPTION
The tracking generator (OPT.74) is a monoblock option
which is integrated in R3131A. It can generate constant level
signal synchronized with sweep frequency in the frequency
range up to 3 GHz and therefore can easily measure the
frequency characteristic of object device. Besides, with the
normalize function which cancels the frequency characteristic
of measuring system, highly accurate measurement is possible.
Because the output level can be set in a wide range (from 0 to
-59.9 dBm, in 0.1 dB steps), it can be used to measure filter
pass characteristic, cable loss, amplifier gain, etc.
For the measurement of reflection characteristic
With the SWR bridge, the reflection characteristic of antennas
and filters can be measured.
For the measurement of cable loss
With the short cable, the high-frequency loss characteristic of
cable can be measured from the differential when the object
cable is connected.
