To view cached peaks:
1) After enabling cached peaks, connect an antenna or probe that supports nearly the full 6 GHz
bandwidth of the MESA, such as the Fixed Dipole Antenna.
2) Notice at full span, the resolution bandwidth is 312.50 kHz. Zoom in 2 times using the Zoom In
onscreen button.
3) Notice that the resolution bandwidth has now changed to 39.0620 kHz. Note the faint red line
above the peak trace. This is the cached peak trace from the 312.50 kHz resolution.
4) Zoom in 2 more times using the Zoom In button. Notice that the resolution bandwidth has now
changed to 9.7650 kHz. There are now two faint lines above the peak trace. The lightest one,
with the highest noise floor, is the cached peak from the 312.50 kHz resolution. The slightly
darker one with the lower noise floor is the cached peak from the 39.0620 kHz resolution.
Note: The 312.50 kHz resolution cached peak and the 39.0620 kHz cached peak are the only peaks that
are cached. Continued zooming will result in increasingly finer bandwidth resolutions, no other cached
peaks will appear.
Note: The noise floor of the cached peaks will be significantly higher than that of the active trace and
peak trace. This is because the cached peak was collected at a coarser bandwidth resolution. These will
also appear more segmented for the same reason.
