[1] Threshold value
[2] Button for switching to the frequency domain measurement panel
[3] Threshold value adjustment
Sets the threshold for the RSSI absolute level. Levels that exceed this value change colour.
When the control is active, you can make fine adjustments with the centre wheel of the mouse or the keyboard up
and down arrow keys.
[4] Station to measure
Specify the station to measure.
[5] Measurement item
Select which to measure between the floor noise level and received signal level. To measure the received signal
level of the source station, the matching station (target station) is necessary.
[6] Measurement mode
* Repeat:
The repeat measurement mode. When the set number of samples are gathered, the program goes back
to the start and continues with measurement. The measurement time interval is set with the sampling time control.
* One shot: Measurement stops when the number of samples set with the sampling number control is reached.
The measurement time interval is set with the sample time control.
[7] Enable area line function
Selects whether to show area lines on the graph.
[8] Start/stop button
Starts and stops measurement. You can stop during measurement in all modes.
[9] Enable point function
Selects whether to show points on the graph.
[10] Sampling time control
Sets the sampling time for the timer measurement mode. The unit is ms, and the minimum value is 100 ms. You can
set steps of 100 ms with the up and down buttons, and you can also enter a value directly from the keyboard. In this
case, double click the field and enter a value. The colour changes when a value is entered. Press the Enter key and
check the value. To measure the received signal level at the target station and the source station, it is required to set
the sampling time to a proper value, especially for using relay stations, ensure that radio wave collisions are avoided.
This evaluation program automatically adds a minimum of 260 ms for a 1:1 system and pluses another 260 ms per
relay station when route information is set with the route setting panel.
