Return Loss: 0.00 to 60.00 dB
VSWR: 1.00 to 65.00
Horizontal Range: 0 to (# of data pts –1) x Resolution to a maximum of
1497m (4911 ft)
# of data pts = 130 or 259 or 517
Horizontal Resolution (rectangular windowing):
Resolution (meters) = (1.5 x 10
8
) x (Vp)/DF
Where Vp is the relative propagation velocity of the cable and DF is the stop frequency minus the
start frequency (in Hz).
