Min. impedance 25MHz: 90Ω, 100 MHz : 160Ω
Recommended installation method
(6) Refer to the following diagram regarding wiring disconnections when volt-
age input is being used.
Example: If analog input device 2 is outputting 5 V and the same power sup-
ply is being used for both devices as shown above, approximately 1/3, or 1.6
V, will be applied to the input for input device 1.
If a wiring disconnection occurs when voltage input is being used, the situa-
tion described below will result. Either separate the power supplies for the
connected devices, or use an isolator for each input.
