5.1.1.2.2 Extreme power source voltages
For tests at extreme voltages, measurements shall be made over the extremes of the power source voltage range as
declared by the manufacturer.
When the equipment under test is designed for operation as part of and powered by another system or piece of
equipment, than the limit values of the host equipment or combined equipment as stated by the manufacturer shall apply
to the combination to be tested.
5.1.2 Test mode
Unless otherwise specified, the measurements shall be performed using normal operation of the equipment with the
equipment operating with the worse case modulation scheme. For each of the requirements in the present document, this
worst case modulation scheme shall be declared by the manufacturer and documented in the test report. Special
software may be used to operate the equipment in this mode.
NOTE: The worst case operational mode is that mode resulting in the worst results with regard to the
requirement.
For frequency hopping systems the equipment should allow specific hop frequencies to be selected manually to
facilitate some of the tests to be performed.
5.1.3 Antennas and transmit operating modes
5.1.3.1 Integrated and dedicated antennas
The equipment can have either integral antennas or dedicated antennas. Dedicated antennas are antennas that are
physically external to the equipment and that are assessed in combination with the equipment against the requirements
in the present document.
NOTE: It should be noted that assessment does not necessarily lead to testing.
An antenna assembly referred to in the present document is understood as the combination of the antenna (integral or
dedicated), its feeder (e.g. coaxial cable) and if applicable, its antenna connector and associated switching components.
The gain of an antenna assembly (G) in dBi, does not include the additional gain that may result out of beamforming.
Smart antenna systems may use beamforming techniques which may result in additional (antenna) gain. This
beamforming gain (Y) is specified in dB. The individual antennas used by smart antenna systems are considered to have
identical gain referred to as antenna assembly gain (G). Beamforming gain does not include the gain of the antenna
assembly (G).
Although the measurement methods in the present document allow conducted measurements to be performed, it should
be noted that the equipment together with all its intended antenna assemblies shall comply with the applicable technical
requirements defined in the present document.
5.1.3.2 Smart antenna systems and related operating modes
Smart antenna systems can operate in various operating modes by which the numbers of active antennas vary depending
on the mode.
5.1.3.2.1 Operating mode 1 (single antenna)
The equipment uses only 1 antenna when operating in this mode.
The following types of equipment and/or operating modes are examples covered by this category:
• Equipment with only one antenna.
• Equipment with 2 diversity antennas operating in switched diversity mode by which at any moment in time
only 1 antenna is used.
