Economical alternative for measurements on
controlled impedance lines
Passive broadband probes are an economical, yet power-
ful alternative to active probes for measuring high-speed
signals on low impedance lines. In contrast to active
probes, their input impedance is low but remains practi-
cally constant over the entire frequency range. They fea-
ture an extremely low input capacitance and particularly
low noise. Their purely passive implementation renders
them highly linear and therefore ideal for spectrum analy-
sis applications.
The R&S®RT-ZZ80 8 GHz probe provides an attenuation
factor of 10:1 at an input impedance of 500Ω||0.3pF. Its
SMA plug is connected to the oscilloscope via the provid-
ed SMA-BNC adapter. The probe can be easily selected as
a predefined probe from the R&S®RTO oscilloscope menu.
And with these simple steps, the instrument is correctly
configured.
Passive broadband
probes
Low noise, high linearity and a purely passive
implementation make passive broadband probes
an economical solution for measuring controlled
impedance lines. The compact design facilitates
measurements on densely packed printed boards.
