9. Note the reading on the power meter. It should be approximately -10 to -8 dBm. Save
this value as it will also be used for computing the Peak to Average Transmit Power ratio
as described in section 5.6.
Expected Results:
The power meter reading should be between -10 and – 8dBm.
5.6. Peak Envelope Power Test
Summary Description: This test computes the peak envelope power (PEP) of a transceiver.
The peak-to-peak amplitude of the transceiver output is measured in this procedure then the
PEP is determined using the equation below. This is a wired test that uses a 20 GHz bandwidth
sampling oscilloscope with a time domain reflectometer plug-in. The transceiver is run in
continuous, unframed transmit mode during this test. This test has no relationship to the FCC’s
narrow bandwidth peak test.
Note: Peak envelope power is a standard term used to measure transmitter power. It is
defined as the emitted power averaged over the RF cycle having the greatest
amplitude during a transmission. In other words, it is the power that a continuous sine
wave would deliver to the load if the peak amplitude of that sine wave matched that of
the largest RF cycle that ever occurs during a transmission.
Prerequisites:
• Run the Transmit Spectral Mask Compliance Test (see section 5.3.2) and Total Average
Transmit Power Test (see section 5.5), if you have not already done so, before starting
this test.

Test Procedure
1. Set up equipment as indicated in Figure 7. Follow the guidelines in section 5.2.1 when
making or breaking RF connections.
2. Turn on all test equipment and allow it to warm up for the length of time specified by the
manufacturer.
3. Verify that the transceiver is powered on.
4. Open a command window on the Linux PC.
