4 Test conditions
4.1 General
The present document relates to the testing of the EPS, and seeks to ensure that an EPS which is compliant to the
provisions of the present document will, when used with a compatible UE which is compliant to the applicable
provisions of the ETSI EN 301 489 [i.7], comply with the requirements of ETSI EN 301 489-1 [1].
The present document describes testing the EPS with a Representative generic test load, which is intended to emulate a
UE for the purpose of testing the EPS.
Because the choice of UE may have some impact on the EMC performance of the EPS certain criteria and/or limits
have been tightened beyond those applied in the case of testing intended to determine the compliance of a specific
EPS - UE combination. Such specific combinations may be tested as described in other parts of the ETSI
EN 301 489 [i.7], but such testing does not demonstrate compliance to the requirements of an EPS.
The provisions of ETSI EN 301 489-1 [1], clause 4.2 shall apply with the following modifications:
• The EPS shall be connected with a Representative generic test load exercising the DC output port.
• Adequate measures shall be taken to avoid the effect of immunity RF test signals on the measuring equipment.
• Measurements shall be taken with the cable supplied with the EPS at the USB Micro-B port. The type and
length of cable used shall be recorded in the test report.
4.2 Arrangements for test signals
Adequate measures shall be taken to avoid the effect of immunity test signals on both the measuring equipment and the
signal sources for the wanted signals located outside the test environment.
4.3 RF exclusion band of radio communications equipment
Not applicable.
4.4 Narrow band responses of receivers or receivers which are
part of transceivers
Not applicable.
4.5 Normal test modulation
Not applicable.
ETSI

9 ETSI EN 301 489-34 V2.1.1 (2019-04)
4.6 Representative generic test load
An EPS Representative generic test load which is representative of a UE shall have the following characteristics:
• A USB Micro-B socket connection.
• An input capacitance of 1 μF in parallel with the EPS output.
• An input impedance with switchable range of:
- 10 k Ω (for 0 % rated current).
- Selection of resistances to obtain the currents and output voltages of the test procedures.
NOTE: Current range 500 mA to 1 500 mA, see CENELEC EN 62684 [3].
- A resistance to obtain Maximum rated current.
• A shielded casing/enclosure as given in CENELEC EN 62684 [3].
5 Performance assessment
ETSI EN 301 489-1 [1], clause 5 shall apply with the following modification stated in clause 6.
6 Performance criteria
6.0 General
For the EPS, the performance criteria are based on a UE intended to be used with the EPS. For some specific test cases
a different compliance level and/or performance criteria has been defined in order to ensure the compliance at the UE
and EPS.
The performance criteria are used to make a decision on whether an EPS passes or fails immunity tests.
For the purpose of the present document two categories of performance criteria apply:
• performance criteria for continuous phenomena applied to EPS;
• performance criteria for transient phenomena applied to EPS.
6.1 Performance criteria for EPS
For an EPS the performance criteria for continuous phenomena shall meet the requirements whilst tested with the
representative generic test load as given below.
The EPS shall meet its specification points on voltage ranges as given below, during and after continuous phenomena
and after transient phenomena:
• Output Voltage 5 V ± 0,25 V from no load to maximum output current measured at the USB Micro-B plug,
while connected to the generic test load defined in clause 4.6.
While the parameters above should be monitored at the USB Micro-B plug, the reference for the output voltage is the
USB Micro-B plug for an EPS with captive cable and the Standard-A plug for an EPS with detachable cable.
The above criteria shall also be met after exposure to transient phenomena.
ETSI
---------------------- Page: 9 ----------------------
10 ETSI EN 301 489-34 V2.1.1 (2019-04)
The following criteria shall be met after exposure to all immunity phenomena tests:
• Output Voltage Ripple (Under load conditions from idle to full): 80 mVp-p measured at 20 MHz bandwidth
using the test method as defined in CENELEC EN 62684 [3].
