Caution
PTP 550 supports Automatic Transmit Power Control (ATPC) where the Slave devices are
instructed by the Master to adjust their Tx power in order for the Slave device signal (UL
RSSI) to arrive at the Master at a predetermined RSSI level (configurable on the Master
under Configuration>Radio>Power Control>Slave Module Target Receive Level). This
feature is beneficial to keep the overall noise floor in the sector to an acceptable level.
However, the feature negates the purpose of eAlign measurements on the Master device
since, during the alignment, the Slave may constantly change its Tx power. It is
recommended to turn off ATPC and set the Slave Tx power to maximum allowable power
during alignment.
While aligning the link using eAlign, please follow these steps:
Procedure:
1
On the Slave, set Configuration>Radio>Power Control>Max Tx Power to Manual.
2
Set Configuration>Radio>Power Control>Transmitter Power to 30 dBm (or maximum value
allowed by regulations).

Once alignment is complete, set Configuration>Radio>Power Control>Max Tx Power back to
Auto

Tools > Wireless Link Test page
Use the Wireless Link Test page to conduct a simple test of wireless throughput. This allows
user to determine the throughput that can be expected on a particular link without having to
use external tools.
