5.1.5 Power Calibration
DO NOT USE THIS PROCEDURE TO SET THE TX OUTPUT
POWER. REFER SECT 5.1.8 TX POWER ADJUST TO DO THIS.
Power calibration affects the forward and reflected power meters on the
Diagnostics Screen as well as the low forward power trip point for the
MX800. This procedure requires a power meter and the relevant leads to
connect the transmitter output to the meter. Power calibration is done using
MXTOOLS via the Calibration Screen. To complete the power calibration,
follow the instructions that MXTOOLS provides.
Once power calibration has been completed the configuration information
must be sent again. Check that the low forward power trip point is set
correctly. The calibration affects the low forward power trip point and thus
the configuration information must be sent to update it according to the new
calibration information.
5.1.6 RSSI Calibration
The RSSI calibration is used to calibrate the RSSI meter on the MXTOOLS
Diagnostics Screen. The procedure requires an RF signal generator and the
relevant leads to connect the signal generator to the RF input of the MX800
Base Station. RSSI calibration is done via the MXTOOLS Calibration
Screen. To complete the RSSI calibration, follow the instructions that
MXTOOLS provides.
5.1.7 Temperature Calibration
The temperature calibration is used to calibrate the temperature meter on the
MXTOOLS Diagnostics Screen and the temperature controlled switch/alarm
points. The procedure requires dummy cable for SKB on the micro controller
having a 2060-ohm resistor between pins 4 and 6 of this connector of the
MX800 Base Station. Temperature calibration is done via the MXTOOLS
Calibration Screen. To complete the temperature calibration, follow the
instructions that MXTOOLS provides.
5.1.8 TX Power Adjustment
The transmitter power setup is used to set the correct power for each channel.
This can be done on a per channel basis or all channels can be set at once.
Power setup is done using the Channel Screen in MXTOOLS. To complete
this test the transmitter output needs to be connected to a power meter.
To set all channels at once select the ‘Lock Data’ option on the Channel
Screen. Click on the alignment channel to bring up the Channel Edit Screen
and allow editing of the channel parameters.
