Noise
■
Start - When this button is pressed, the PLC node starts scanning the powerline.
■
Stop - When this button is pressed, the PLC node stops scanning the powerline.
■
Sampling Interval (msec) - This field specifies the duration between two consecutive samples.
The minimum value required is 200 msec and maximum is 2000 msec.
■
Transmit to Clear - When this checkbox is selected, the PLC device transmits a packet in
unacknowledgement mode so that the other nodes do not transmit any packet for at least the
minimum BIU interval. This is recommended for systems that may have other PLC devices
transmitting while the noise is being measured. After this device transmits, the line is free while all
the devices wait to acquire the line (BIU detection interval). For correct operation, the minimum
BIU time interval should be atleast 50 msec.
■
Noise Values (dBµV) - This window displays the noise values sampled.
■
Export - When this button is pressed, the noise values are exported to a MS Excel spreadsheet.
■
Clear - This button clears the Noise Values window
Statistics
■
Average - This field shows the average of the noise values.
■
Highest - This field shows the highest noise value sampled.
■
Lowest - This field shows the lowest noise value sampled.
■
Clear Statistics - When this button is pressed, the statistics are reset.
