1 Base Station Specifications

The performance figures given in these specifications are applicable only
to equipment operating as an integral part of a TB9400 base station. These
performance figures are minimum figures, unless otherwise indicated, for
equipment operating at standard room temperature (+22°C to +28°C
[+71.6°F to +82.4°F]) and standard test voltages as follows:

■ AC power management unit (PMU) - 120VAC and 230VAC

■ 12V DC PMU - 12VDC

■ 24V DC PMU - 24VDC

■ 48V DC PMU - 48VDC.

The TB9400 is available in the following configurations:

■ 50W single or dual base station with PMU

■ 100W single base station with PMU

■ receive-only base station - up to four receivers (receive-only reciters)

with PMU.

Notice The software release notes list known issues or limitations of
the base station that may vary from the specifications published in this
document. Please refer to the current software release notes for any vari­ations to the specifications in this document.

1.2 Frequency Bands and Sub-bands

Many of the performance figures in this manual are applicable to all
frequency bands. In some cases the figures refer to specific bands or sub­bands, and these are identified with the letters listed in the following table.

The table also indicates which base station configurations are currently
available in each frequency band.

Refer to “Compliance Standards” on page 44 for details about which bands
or sub-bands have been tested and approved to appropriate national and
international compliance standards.

In Brazil, for K band, the TB9400 is considered to be configured as a base
station with retransmission of receive frequencies.

a. User-programmable alarms can be set for low or high battery voltage, using the web interface. The alarms will be triggered

when the set voltage levels are reached. These limits are subject to the tolerances of the battery protection circuitry, as
stated in “Battery Protection (Fail-safe) Limits” above.

b. The user-programmable startup and shutdown limits allow for adjustable startup and shutdown voltages. Using the web

interface, these limits can be adjusted for different numbers of battery cells, or for the particular requirements of the base
station operation. Once the limits are reached, the PMU will shutdown. These limits are subject to the tolerances of the
battery protection circuitry.

c. The battery protection limits are set in hardware at the factory and cannot be adjusted by the user. These limits will not be

reached under normal operation conditions, but are provided as “fail-safe” measures to protect the battery from deep
discharge.

d. When the input voltage drops below the battery protection undervoltage shutdown limit, and until the voltage rises above the

battery protection startup voltage.

e. At initial power-up; or, after battery protection has occurred, when the input voltage rises above the battery protection startup

voltage (PMU now under control of its microcontroller), but is still below the user-programmed startup voltage

1.4 Power and Current Consumption

The specifications in this section refer to the TB9400 base station fitted
with a PMU. The performance figures are typical figures.

The transmit measurements were carried out with the base station
transmitting at the stated RF output power with all front panel fans running.
The standby measurements were carried out with the base station not
receiving or transmitting and no front panel fans running. All
measurements were carried out with no load on the auxiliary power supply.
