INFORMATION FOR TYPE APPROVAL
3.3.2
Details on EMC
When the device is exposed to electromagnetic emissions the lower limits of the ranges in table 3.11 are
increased by 5 dB. Within these changed ranges the error limits according to IEC 61672-1:2014 are main-
tained. The level linearity range changes to 40
. . .
107 dB(A) when the device is exposed to electromagnetic
emissions. There will be no performance loss in the device after electrostatic discharges (touch discharge
up tp 4 kV and air discharge up to 8 kV).
ATTENTION!
Legally binding measurements
must not
be performed, if the device is con-
nected to public power supply.
3.3.3
EMC test
The measurement is performed for the following configurations:
Low interference immunity:
USB cable linked to public power supply and microphone extension cable
connected
Maximim interference immunity:
USB cable and microphone extension cable disconnected
3.3.4
Mains frequency and high-frequency fields
Tango_Plus complies with IEC 61672-1:2014 with respect to interference immunity to mains frequency and
high-frequency fields. The interference immunity to mains frequency and high-frequency fields is highest
when the device is running on batteries/rechargeables without USB cable connected.
Figure 3.11: Alignment measurement HF immunity
If Tango_Plus is connected to a PC and measuring high-frequency emissions are highest. Additionally, the
interference immunity to mains frequency and high-frequency fields is lowest in this configuration (alignment
see fig. 3.11). The next lowest emission level is reached in the same configuration, but in STOP-Mode.
