the channels is too large then you may wish to calibrate and align every channel. (In most
cases this will not be necessary.) Both individual and group alignment will be covered.
The channel may be selected via the Channel Screen in MXTOOLS using the software
channel select or in hardware via the internal channel dip switch or via the rear channel
select. (Refer to section 2.2.2.3 for additional help.) This channel will then be used when
performing the following procedures.
5.1.5. Power Calibration
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. (Refer
to the MXTOOLS User Manual for additional help.)
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. (Refer to the MXTOOLS User Manual for
additional help.)
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 2045 ohm resistor between pins 4 and 6
of this connector on the MX800 Base Station. Temperature calibration is done
via the MXTOOLS Calibration Screen. To complete the temperature calibration follow the
instructions that MXTOOLS provides. (Refer to the MXTOOLS User Manual for
additional help.)
