Multi LAN 350
Specifications
19
Note:
Additional error sources that affect the distance measurements:
-Uncertainy of NVP (nominal propagation speed)
-Attenuation at high frequencies dramatically influences the accuracy at long distances
(over 200m).
-Accuracy of distance is defined only on cable opens or shorts.
-Percentage of amplitude is scaled to nominal pulse amplitude into 100
Ω
(100%).

Note:
Additional error sources that affect the distance measurements:
Uncertainty of NVP (nominal propagation speed)
Attenuation at high frequencies influences the accuracy at longer distances.
-Percentage amplitude is scaled to nominal pulse amplitude into 100
Ω
(100 %).
Note:
All specifications for tests apply to cable with characteristic impedance of 100
Ω
and at the temperature of 25
°
C. In case the instrument is moistened, it must be
dried at least 2 hours before use.
Accuracy is defined in the frequency range given from 1 MHz – 250 MHz).
Because of simplicity the accuracy of Attenuation, NEXT, ELFEXT and Return
Loss accuracy is given only at 100 MHz and 250 MHz. Contact the manufacturer
for more detailed information.
