P80318
The P80318 is an 18 GHz 100 Ω input impedance differential TDR
hand probe. This probe enables high-fidelity impedance measurements
of differential transmission lines. The adjustable probe pitch enables
a wide variety of differential line spacing and impedances. The P80318
probe also includes two precision SMA cables with parallel control
lines that provide the 80A02 the control for EOS/ESD protection.
P80318X
The P80318X is designed for high-volume PCB
impedance test applications. These applications require maximum manufacturing
up-time. The P80318X includes everything in a P80318 plus a second
probe body for use if the first probe body needs to be serviced due
to normal wear.
The P80318 probe can be used as a standalone
high-resolution probe, but it is specially designed to be used with
two 80A02 EOS/ESD Protection Modules. To maximize testing up-time
and minimize repair costs, protecting the sampling module from static
damage is a requirement. Damage to the sampling module is typically
due to electro-overstress (EOS) and electrostatic discharge (ESD)
from large static charges stored in the DUT. Use of two 80A02 modules
ensures proper probe grounding prior to switching signal to the sampling
module.
