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

Description

Name

input

Sets the sensivity range, the power sensor uses.

sensivity

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

FAST

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

Here you may enter the frequency of the measured signal in MHz. If this parameter is not

compensation

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

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

Defines the alarm threshold value. If the displayed power value (with any user defines

threshold

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.
