Transmit Power Calibration Test (Autoplex Series II)
This test provides an analog display of power measurements. This mode is useful when
making adjustments to power levels on a transmitter.
This test may be performed in-service using the Base Station TX Test Port, or
out-of-service using the Base Station TX Antenna Port (see “Which Base Station Port to
Use – TX Test or TX Antenna?” on page 36).
Features of the power meter display include:
• Tick marks on the meter to indicate when a power level setting is within the desired
limits.
• Audible tones to indicate whether the power reading falls within specified limits.
Make certain to use the correct Test Set input port for the power level to be measured
(see “Which Test Set Port to Use – ANT IN or RF IN/OUT?” on page 36).
For Automated Base Station Control:
If you have configured the Test Software to control the Base Station automatically,
the Test Software will send a command to the MSC to set the BCR attenuation to the
level specified on the Base Station Configuration Menu screen.
However, the Test Software cannot override a minimum BCR attenuation level that
has been set in the translation tables of the MSC CEQFACE form. If the measured
power is not within specifications, make certain that the BCR Attenuation setting on
the Base Station Configuration Menu screen is not set to a lower value than the
minimum BCR attenuation level listed in the translation tables.
For Manual Base Station Control:
If you have configured the Test Software to require manual control of the Base
Station, make certain that the BCR Attenuation setting on the Base Station
Configuration Menu screen matches the BCR attenuation setting on the MSC
CEQFACE control form. If these values are different, the TX Power Meter
measurement might be incorrect.
NOTE Transmitter power is partly controlled by the MSC using the BCR attenuation setting.
The value for this setting, and the corresponding TX power of the Base Station, varies
between models of Base Station and individual Base Station location.
It is very important that you set correctly the BCR Attenuation Level and Specified
Output Power on the Base Station Configuration Menu screen (see “Base Station
Configuration” on page 41).
