4.7.1 WAAS Mode Bar Chart
When operating the RX 400p receiver in WAAS mode, the portion of the bar chart to
the right of the WAAS mode indicator, A, reflects WAAS tracking performance. The
WAAS bar chart will reflect the quality of the bit error rate (BER) for WAAS signal
reception. A higher bar is indicative of a better BER.
A good BER is zero and no lock is 500 or greater. A full height bar (16 pixels tall,
including both the top and bottom rows of the display) represents a BER of zero as
shown below. A BER of 500 or greater will be displayed with minimum bar height,
and will be only 2 pixels tall. Intermediate quality signals are shown with a bar
height relative to the reception quality.

In the case of WAAS, since there are two WAAS satellites available, two BER’s are
provided. The first bar is for WAAS PRN 122 and the second for WAAS PRN 134.
4.7.2 OmniSTAR Mode Bar Chart
When operating the RX 400p receiver in OmniSTAR mode, the portion of the bar
chart to the right of the OmniSTAR mode indicator, +, reflects OmniSTAR tracking
performance. The OmniSTAR bar chart will reflect the quality of the bit error rate
(BER) for OmniSTAR signal reception. A higher bar is indicative of a better BER.
A good BER is zero and no lock is 500. A full height bar (16 pixels tall, including
both the top and bottom rows of the display) represents a BER of zero as shown
below. A BER of 500 will be displayed with minimum bar height, and will be only 2
pixels tall. Intermediate quality signals are shown with a bar height relative to the
reception quality.
