3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in ETSI EN 301 489-1 [1] and the following
apply:
carrier-on state: transmit ES is in this state when it is authorized to transmit, and when it transmits a signal, either
authorized by a Centralized Control and Monitoring Function (CCMF) or a Network Control Facility (NCF) when
designed for unattended operation or by local control when designed for attended operation
carrier-off state: transmit ES is in this state when it is authorized to transmit, and when it does not transmit any signal,
either authorized by a CCMF or a NCF when designed for unattended operation or by local control when designed for
attended operation
NOTE: The existence of a carrier-off state depends on the system of transmission used. For ES designed for
continuous transmission mode there may be no carrier-off state.
transmission disabled state: transmit ES is in this state when it is not authorized to transmit either by a CCMF or a
NCF respectively when designed for unattended operation or by local control when designed for attended operation

10 ETSI EN 301 489-12 V3.1.1 (2019-04)
For the tests, the ES antenna reflector and the test antenna may be removed at their flanges and be replaced by one
direct wave guide connection.
The following test equipment shall be the means whereby the correct operation of the EUT is verified:
a) the power meter measures the output power and is used to confirm the transmission disabled, carrier-on and
carrier-off states and output level consistency;
b) the frequency counter measures the centre frequency of the radiated carrier in the absence of modulation;
c) the spectrum analyser measures the bandwidth of the transmission;
d) the test receiver is used to demodulate the transmitted signal;
e) the two QTMA are used in conjunction with each other to assess the quality of transmission;
f) the test transmitter is used to control the switching between transmission disabled, carrier-on and carrier-off
