Ofdm Channel; Ofdm Detection Continuous Pilot Harmonics - Arcom QAM Snare Snoop User Manual

OFDM channel

To select the OFDM channel, navigate down to the
Channel line, press enter, and use the arrows to select the
desired frequency.

OFDM detection continuous pilot harmonics

Two harmonics of the OFDM continuous pilots are utilized
for OFDM detection. The two harmonic frequencies MUST
both we within the bandwidth of the selected OFDM channel,
and for optimum performance the two harmonics should be
selected at the maximum spacing within the channel. The
EXACT frequency of each pilot harmonic must be entered. It
is recommended that the device is configured to enable the
Auto Detection Profile such that exact harmonic frequencies
do not need to be loaded into the detector, and the detector
acquires the information from the QS Server. The method to
determine the pilot harmonic frequency is beyond the scope
of this document, consult with your supervisor to get the proper frequency
information.
If it is required to add this information manually to the detector, once the frequency
information is acquired, first navigate to the CP1 line item and press enter. The cursor
will move to the first frequency digit. If this digit needs to be changed, press enter,
then use the left and right arrow to increment or decrement the digit. Press the enter
button to confirm the selection. The use the right arrow to move to the next digit that
needs to be changed and repeat the process. The right arrow can also be used to skip
digits if they do not need to be changed. Once this process is finished, continue to
press the right arrow to highlight MHz, and the entire line as entered will be accepted.
Then for the next CP2 line, repeat the process for the second harmonic of the
continuous pilot within the selected channel bandwidth – press the right arrow to move
the cursor to the far right to accept changes. Frequencies can also be configured using
the Q-browser, and it is recommended to do so such that the exact frequency can be
