3.3 Operational Parameters
The page 'Setup' contains the power sensor's operational parameters. The page displays a table with the parameters actually set as a browser entry form. To change a parameter, enter the new value or select the desired option from the drop down list and then click to the 'SUBMIT' button at the bottom of the page. Parameters remain unchanged unless you click to this button.
The table below lists the settings provided by this page.
- Parameter Name --- Description
- input sensivity --- Sets the sensivity range, the power sensor uses.
- AUTO --- makes the power sensor select the appropriate range automatically.
- LOW --- selects the low sensivity range (for high levels).
- HIGH --- selects the high sensivity range.
It is strongly recommended to operate the power sensor with AUTO setting.
- averaging --- Sets the filter, the power sensor applies to the measured values. Valid choices are
- OFF --- no averaging.
- FAST --- the sensor displays the average of 8 readings.
- SLOW --- the sensor displays the average of 48 readings.
Averaging is done on the base on the 8 or 48 samples the power sensor recently read.
- frequency compensation --- Here you may enter the frequency of the measured signal in MHz. If this parameter is not zero, the power sensor looks up the frequency response calibration offset for the given frequency and adds this offset to each measured value before it is displayed. The power sensor accepts integer numbers on the range 0 .. 19000.
- additional level offset --- The value [dB] specified with this parameter is added to the measured power before it is displayed and compared to the fault threshold value. If value is set to zero, the power sensor shows the power which is measured at it's input connector. The valid range for 'offs' is -99.99 to 99.99.
- alarm threshold --- Defines the alarm threshold value. If the displayed power value (with any user defines offset and frequency response calibration already applied) drops below this limit, the power sensor reports a 'low signal' alarm and opens the fault relay contact. To disable the threshold, set it to -99.99.
- note --- You may enter a note / comment here which replaces the 'Power Reading' label on the power sensor's entry page. The label may be set to describe what the power sensor actually is measuring.
