FL: Lowest frequency of the power envelope, it is the frequency furthest below the frequency of maximum
power where the output power drops below the level of –80 dBm/Hz spectral power density (-30 dBm if
measured in a 100 kHz bandwidth) eirp.
FH: Highest frequency of the power envelope, it is the frequency furthest above the frequency of
maximum power where the output power drops below the level of –80 dBm/Hz spectral power density
(-30 dBm if measured in a 100 kHz bandwidth) eirp.
NOTE: ACnom =AC230V/50Hz;ACmin = AC207V/50Hz; ACmax= AC253V/50Hz
TEST RESULTS: The unit does meet the requirements.

4.3 DWELL TIME
4.3.1 LIMITS
EN300 328 clause 4.3.4
The maximum dwell time shall be 0,4 s.
4.3.2 TEST PROCEDURE
Remove the antenna from the EUT and then connect a low attenuation cable from the antenna port to the
spectrum.
Set spectrum analyzer span = 0. Centered on a hopping channel;
Set RBW = 1MHz and VBW ≥ 1MHz. Sweep = as necessary to capture the entire dwell time per hopping
channel. Detector Function = Peak. Trace = Max hold;
Use the marker-delta function to determine the dwell time. If this value varies with different modes of
operation (e.g.. data rate. modulation format. etc.). Repeat this test for each variation. The limit is specified
in one of the subparagraphs of this Section. Submit this plot(s). An oscilloscope may be used instead of a
spectrum analyzer.
Pre-test the 3 modulation to find GFSK and 8DPSK is worse case, so only record GFSK and 8DPSK test data.
