un-modulated mode. The UUT shall be connected to spectrum analyser.
Max Hold shall be selected and the centre frequency adjusted to that of the UUT.
The peak value of the power envelope shall be measured and noted. The span shall be reduced
and the marker moved in a positive frequency increment until the upper, (relative to the centre
frequency), -10 dBc point is reached. This value shall be noted as f1.
The marker shall then be moved in a negative frequency increment until the lower, (relative to the
centre frequency),
-10 dBc point is reached. This value shall be noted as f2. The centre frequency is calculated as (f1 + f2) / 2.

ACCEPTANCE CRITERIA:

2.2 NOMINAL AND OCCUPIED BANDWIDTH

Test Conditions: ETSI EN 301 893 V2.1.1

Temperature: 25 deg C
Relative Humidity: <65%RH
Test Conditions:
1. The conformance requirements in clause 4.2.2 shall be verified only under normal operating
conditions, and on those channels and channel bandwidths defined in clause 5.3.2.
The measurements shall be performed using normal operation of the equipment with the
test signal applied (see clause 5.3.1.1).
2. The UUT shall be configured to operate at a typical RF power output level used for normal
operation. When equipment has simultaneous transmissions in adjacent channels, these
transmissions may be considered as one signal with an actual Nominal Channel Bandwidth of
"n" times the individual Nominal Channel Bandwidth where "n" is the number of adjacent
channels. When equipment has simultaneous transmissions in non-adjacent channels, each
power envelope shall be considered separately.
3. For a UUT with antenna connector(s) and using dedicated external antenna(s), or for a UUT
with integral antenna(s) but with a temporary antenna connector(s) provided, conducted
measurements shall be used. In case of conducted measurements on smart antenna systems
(devices with multiple transmit chains) measurements need only to be performed on one of
the active transmit chains (antenna outputs).
4. For a UUT with integral antenna(s) and without a temporary antenna connector(s), radiated
measurements shall be used.
Report No.: Page: 10 of 22
TEST REPORT
Dated: UIN-

TEST PROCEDURE:

Step 1:

Connect the UUT to the spectrum analyser and use the following settings:

Centre Frequency: The centre frequency of the channel under test

Resolution Bandwidth: 100kHz

Video Bandwidth: 300kHz

Frequency Span: 2 × Nominal Bandwidth (e.g. 40 MHz for a 20 MHz channel)

Sweep time: > 1 s; for larger Nominal Bandwidths, the sweep time may be increased until a value
where the sweep time has no impact on the RMS value of the signal

Detector Mode: RMS

Trace Mode: Max Hold

Step 2:
Wait for the trace to stabilize.

Step 3:

Make sure that the power envelope is sufficiently above the noise floor of the analyser
to avoid the noise signals left and right from the power envelope being taken into
account by this measurement.
Use the 99 % bandwidth function of the spectrum analyser to measure the Occupied Channel
Bandwidth of the UUT. This value shall be recorded.
The measurement described in step 1 to step 3 above shall be repeated in case of
simultaneous transmissions in non-adjacent channels.

ACCEPTANCE CRITERIA (As per ETSI EN 301 893 V2.1.1)

The Nominal Channel Bandwidth for a single Operating Channel shall be 20 MHz.
Alternatively, equipment may implement a lower Nominal Channel Bandwidth with a
minimum of 5 MHz, providing they still comply with the Nominal Centre Frequencies defined
in clause 4.2.1 (20 MHz raster).
The Occupied Channel Bandwidth shall be between 80 % and 100 % of the Nominal Channel
Bandwidth. In case of smart antenna systems (devices with multiple transmit chains) each of the
transmit chains shall meet this requirement. The Occupied Channel Bandwidth might change with
time/payload.
During a Channel Occupancy Time (COT), equipment may operate temporarily with an Occupied Channel
Bandwidth of less than 80 % of its Nominal Channel Bandwidth with a minimum of 2 MHz.

2.3 RF OUTPUT POWER AND TRANSMIT POWER CONTROL

Test Conditions: ETSI EN 301 893 V2.1.1

Temperature: 25 deg C

Relative Humidity: <65%RH

Test Conditions:

The conformance requirements in clause 4.2.3 shall be verified on those channels and channel
bandwidths defined in

clause 5.3.2.

The measurements described in the present clause may need to be repeated to cover:

each of the TPC ranges (or transmitter output power levels for equipment without TPC) and
corresponding antenna assemblies declared by the manufacturer (see clause 5.4.1, item e), item f) and
itemg));

each of the transmit operating modes declared by the manufacturer (see clause 5.3.3.2 and clause 5.4.1,
itemc)).

The measurements shall be performed with test signal specified in clause 5.3.1.1 applied. Alternatively, if
special test functions are available, the equipment may also be configured in a continuous transmit mode

TEST PROCEDURE (AS PER ETSI EN 301 893 V2.1.1)

For equipment with continuous transmission capability or for equipment operating (or with the

Capability to operate) with a constant duty cycle (e.g. Frame Based equipment)

This option is for equipment that operates only in one sub-band or that is capable for operation in two
sub- bands simultaneously but, for the purpose of the testing, the equipment can be configured to:

Operate in a continuous transmit mode or with a constant duty cycle (x), and

operate only in one sub-band.

Step 1:

For equipment configured into a continuous transmit mode (x = 1), proceed immediately with step 2.

• The output power of the transmitter shall be coupled to a matched diode detector or
equivalent thereof. The output of the diode detector shall be connected to the vertical channel
of an oscilloscope.
• The combination of the diode detector and the oscilloscope shall be capable of faithfully
reproducing the duty cycle of the transmitter output signal.
• The observed duty cycle of the transmitter (Txon/ (Txon+ Tx off)) shall be notedasx(0< x≤
1),and recorded in the test report.
Report No.: Page: 14 of 22
TEST REPORT
Dated: UIN-

Step 2:

• The RF output power shall be determined using a wide band RF power meter with a thermo
couple detector or an equivalent thereof and with an integration period that exceeds the
repetition period of the transmitter by a factor 5 or more. The observed value shall be noted as A
(in dBm).
• In case of conducted measurements on smart antenna systems operating in a mode with
multiple transmit chains active simultaneously, the output power of each transmit chain shall be
measured separately to calculate the total power (value A in dBm) for the UUT.

Step 3:

• The RF output power at the highest power level PH (e.i.r.p.) shall be calculated from the above
measured power output A (in dBm), the observed duty cycle x, the stated antenna gain G in dBi
and if applicable the beam forming gain Y in dB, according to the formula below. This value shall
be recorded in the test report. If more than one antenna assembly is intended for this power
setting or TPC range, the gain of the antenna assembly with the highest gain shall be used.
PH = A + G + Y + 10 × log (1 / x) (dBm). (5)

This value PH shall be compared to the applicable limit contained in table 2 of clause4.2.3.2.2.

Test Conditions: ETSI EN 301 893 V2.1.1

Temperature: 25 deg C

Relative Humidity: <65%RH

Test Conditions:

These measurements shall only be performed at normal test conditions. The measurement shall

highest frequency of the stated frequency range. These frequencies shall be recorded. For the
duration of the test, the equipment shall not change its operating frequency.

Test Procedure ETSI EN 301 893 V2.1.1

Option 1: For equipment with continuous transmission capability or for equipment operating (or
with the capability to operate) with a constant duty cycle (e.g. Frame Based equipment)

This option is for equipment that can be configured to operate in a continuous transmit mode or
with a constant duty cycle (x).

Step 1:
- Connect the UUT to the spectrum analyser and use the following settings:
- Centre Frequency: The centre frequency of the channel under test
- RBW: 1MHz
- VBW: 3MHz
- Frequency Span: 2 × Nominal Bandwidth (e.g. 40 MHz for a 20 MHz channel)
- Detector Mode: Peak
- Trace Mode: Max Hold

Step 2:
• When the trace is complete, find the peak value of the power envelope and record the frequency.

Step 3:
• Make the following changes to the settings of the spectrum analyser:
• Centre Frequency: Equal to the frequency recorded in step2
- Frequency Span: 3MHz
- RBW: 1MHz
- VBW: 3MHz
- Sweep Time: 1minute
Report No.: Page: 19 of 22
TEST REPORT
Dated: UIN-

- Detector Mode: RMS

- Trace Mode: Max Hold

Step 4:
• When the trace is complete, the trace shall be captured using the "Hold" or "View"

option on the spectrum analyser.

• Find the peak value of the trace and place the analyser marker on this peak. This level

is recorded as the highest mean power (Power Density) D in a 1 MHz band.

• Alternatively, where a spectrum analyser is equipped with a function to measure

spectral Power Density, this function may be used to display the Power Density D in
dBm /MHz.
In case of conducted measurements on smart antenna systems operating in a mode
with multiple transmit chains active simultaneously, the Power Density of each
transmit chain shall be measured separately to calculate the total Power Density
(value D in dBm / MHz) for the UUT.
Step 5:
• The maximum spectral Power Density e.i.r.p. is calculated from the above measured

Power Density D, the observed duty cycle x (see clause 5.4.4.2.1.1.2, step 1), the
applicable antenna assembly gain G in dBi and if applicable the beam forming gain Y in
dB, according to the formula below. This value shall be recorded in the test report. If
more than one antenna assembly is intended for this power setting, the gain of the
antenna assembly with the highest gain shall be used:
PD = D + G + Y + 10 × log (1 / x) (dBm / MHz)
