5.8. Receiver Immunity Test
Summary Description: This test determines the tolerance of the MOTOROLA UWB
implementation to other RF technologies (IEEE 802.11b, IEEE 802.11a, cell phones, Microwave
ovens etc.) using the same frequency bands. It uses the same setup as the Receiver Sensitivity
test. This is a wired test that uses a power splitter and injects tones of various frequencies from
a signal generator into the UWB receiver input then measures the power level of the interfering
signal.
During this test the source transceiver operates in framed mode. In other words, numerous
UWB frames, each with a header and payload, are sent.
Prerequisites:
• Run the Transmit Spectral Mask Compliance Test (see section 5.3.2) and Receiver
Sensitivity Test (see section 5.6), if you have not already done so, before starting this
test.
Connection Diagram
• Use the setup specified in Figure 8.
Test Procedure
1. Set up equipment as indicated in Figure 8. Follow the guidelines in section 5.2.1 when
making or breaking RF connections.
2. Turn on all test equipment except the signal generator and allow it to warm up for the
length of time specified by the manufacturer.
3. Verify that the signal generator is off or set it to no output.
4. Set the manual attenuator to 20 dB.
5. Set the spectrum analyzer as follows:
a. Measurement type: RF Power in dBm
b. Sweep range: 800 MHz to 1000 MHz.
c. Marker: 900 MHz
d. Resolution bandwidth setting: 1 MHz
e. Detector selection: RMS
f. Video bandwidth: Auto
g. Input attenuation: 0
h. Input coupling: AC
i. Trigger source: internal, free running
6. Verify that both the source transceiver and the destination transceiver are powered on.
7. Open a command window on each of the Linux PCs depicted in Figure 8.
