The spectrum of an Orion2 emitting a steady carrier. The serial number is 09C1096 and the software version 2.37.

At a frequency offset of 50 kHz the Y-coordinate is 690.
This figure has 668 pixels for 100 dB and the following results are obtained for the average power in 2.4 kHz bandwidth:
Offset     dY       dY     Corrected dY
(kHz)   (pixels)   (dB)        (dB)       
  0        0        0           0

 10      618      92.5        93.0
 15      607      90.9        91.8
 20      599      89.7        90.9
 50      567      84.9        85.5

Here the frequency of the WSE converter chain is shifted by 50 kHz. The Y-coordinate is 695 at a frequency offset of 50 kHz. In the previous measurement it was 690 in fair agreement with the 0.6 dB (= 4 pixels) expected due to the missing amplitude calibration. At 75 kHz in this image the level is 58 pixels lower which means that the level at 100 kHz offset is 9.3 dB below the level at 50 kHz offset.

Here the frequency of the WSE converter chain is shifted by 100 kHz. The level at 75 kHz is 43 pixels below the level at 25 kHz which means that the level at 150 kHz offset is 7.0 dB below the level at 100 kHz offset with the 0.6 dB correction included.

This figure shows the noise floor when the transmitter is switched off. The system noise floor is about 10 dB below the sideband sideband noise at 150 kHz offset. The sideband noise at 150 kHz offset is therefore at 102.2 dB below the carrier in 2.4 kHz bandwidth when the noise contribution from the measurement system is subtracted.
