Pwr Out
Controls the power level of the signal that is sent out to the RF port. The Signal-
Hawk then measures the power that comes back. The default setting is 0 dBm. Can
be set from -20 to +10 in 1 dB steps. This should be set as high as possible without
overpowering the system.
Note:
For most measurements, the output should be set to 0dBm or
lower.
Note:
For systems with good match (low reflected power) set the
output higher to improve the signal to noise ratio.
Sweep
Sets the parameters of the sweep for the SignalHawk.
Cont/Single
Toggles the sweep setting from a single sweep to a continuous cycle of sweep-
ing and recording.
Note:
Selecting this will enable a manual trigger soft key that starts
the sweep when pressed.
Data Points
Controls the sweep speed and level of detail. The range can go from 12 to 11265
points per sweep.
Note:
Increasing the number of data points increases the measur-
able distance in Distance-to-Fault measurements and increases the
detail in Measure Match mode measurements. Use a smaller number
of points when frequency resolution is not critical & a faster sweep
time is desired. Use more points for a more accurate display of finer
frequency divisions.
