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.
