In addition, this test has two other purposes. First, it determines the throughput (bits per second
of payload) from UWB transmitter to UWB receiver for various FEC and raw channel rate
settings in a line of sight (LOS) environment using a range of scaled antenna separation
distances as simulated with a manual attenuator. This test also measures the effect on FER of
various channel rate and FEC settings. Sample measurements are provided.
Prerequisites:
• Run the Transmit Spectral Mask Compliance Test see (section 5.3.2), if you have not
already done so, before starting this test.

Versus Throughput and Receiver Immunity Tests
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. It will not be used in this test.
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: 500 MHz on either side of the frequency, f

, with the highest output
power as found in steps 9 through 17 of the Transmit Spectral Mask Test described
in section 5.3.2.
c. Markers: 250 MHz above f

d. Resolution bandwidth setting: 50 MHz
e. Detector selection: RMS
f. Video bandwidth: Auto
