where Ε∆ = Directivity - Measured Return Loss
Directivity is the largest source of return loss
measurement uncertainty. The quality of the
load or termination used for calibration determines
directivity performance. Loads can be verified
using a vector network analyzer calibrated with
either sliding load or TRL.

Cable Loss Accuracy
Accuracy: <±1.0 dB typical, for insertion
losses of <4.0 dB.
Assumes cable return loss >26 dB.
Accuracy is improved using ripple averaging. Set
the frequency sweep such that 5 to 6 ripple cycles
are visible. Calibrate the Site Master and place
markers at an adjacent peak and valley. Sum the
marker values and divide by two. For cable loss
greater than 4.0 dB, see formula in technical notes.
Repeatability: <± 0.05 dB, typical
Cable Loss is determined by measuring one end of
the cable and disconnecting the opposite end from
any antennas or other devices. This open circuit
condition return loss is measured and divided by
two. This test is excellent for trouble shooting or
verifying previously installed cables. For best
results comparing measurements to historic data,
always disconnect the opposite cable end at the
same position and avoid simultaneous tests of
multiple cable or connector types.
Distance-To-Fault Accuracy:
The Fast Fourier Transform which calculates
the DTF display provides an exact indication of
electrical length. This relates to physical length
through knowledge of the cable’s propagation
velocity, ν
p
:
d = ( c * n * ν
p
) / ( 2 * ∆f )
Distance is displayed according to the accuracy of ν
p
.
In the equation above, c is the speed of light,
n the number of ripples in the frequency domain
display and ∆f is frequency sweep range. Cable
manufactures specify the ν
p
of cables. When this
specification is not available, the ν
p
value is easily
determined by measuring a known length of cable.
Non-phase stable cables will cause small
measurement errors because bending of the cable
changes the physical length of the cable’s center
conductor and outer ground shield. The Open,
Short and Load components used during calibration
create a phase “reference plane” from which Site
Master bases the vector error correction formulas.
If the physical length of the cable is allowed to
change as it flexes, the phase relationship of the
calibrated reference plane position and the actual
cable end position also changes - creating errors.
The protective softcase is designed to hold
calibration components. Velcro adjustments
on the shoulder strap allow convenient, one
hand operation.
Panel connections include a 9 pin D-sub RS-
232, precision test port connector, DC power
input, and an optional RF detector connection
for the Power Monitor operation.
