v. Block and spurious response suppression
The block and spurious response suppression is to test the
capability that the BSS transmitter receives the GSM modulation
signal when interferential signal exists.
Compliant with GSM 11.21 and GSM 05.05.
vi. Inter-modulation suppression
This index is for measuring the linear degree of the RF part of the
transmitter. It indicates, when two or multiple unexpected signals
which are relative to the expected signal in frequency exist, the
transmitter’s capability of receiving the respected modulation signal
is not over the given degraded quantity.
Compliant with GSM 11.21 and GSM 05.05.
vii. AM suppression
AM suppression means the transmitter’s capability of receiving the
expected modulation signals is not over the given degraded
quantity when an unexpected modulation signal exists.
Compliant with GSM 11.21 and GSM 05.05.
viii. Spurious emission
The spurious emission is the emission on the frequencies except
that of the RF channel of the transmitter and adjacent frequencies.
Compliant with GSM 11.21 and GSM 05.05.
