Carrier Drift Test Results
Standard and single packet modes
1. Choose “Carrier drift” from the Script menu.
2. Press the [Results] soft key.
The Carrier drift results screen is displayed.
Definition of test results
Drift rate Displays the maximum drift rate between any two 10-bit groups in the
packet, separated by 50µs. This value is the peak held worst case value for
packets measured during the test.
Drift (DHX) Displays the difference between the average frequency of the first 4
preamble bits of the packet and the average frequency of any 10 bits in the
payload field of the same packet. This value is the peak held worst case
value for packets measured during the test.
3. Press the [Extended] soft key to display more detailed test results. As opposed to
the summary screen shown above, the extended screens are specific to each of the
test scenarios. For example, if a test is performed at high, medium, and low
frequencies, with hopping both on and off, there would be six extended screens. An
example of the first extended screen for the carrier drift test is shown below.
Note: “Packets Tested” refers to the total of all packets tested (i.e., at DH1, DH3, and
DH5)
4. Page through the extended screens with the soft key in the normal manner, or press
the [Summary] soft key to revert to the initial summary page.
