Vaisala RVP900, User Manual, Page: 129 / 484

When the overall frequency response of your Tx/Rx is not flat, you can tune this parameter
to null out the error based on feedback from either the
Ps
spectrum plot or oscilloscope
display of the Tx pulse.
FM Chirp manual spectrum flattener: 0.00 %–per–MHz

5.2.8 M+ Debug Options
RVP900 debugging options help you develop and debug application code. You can also use
these questions to put RVP900 in unusual operating states. These options are usually
disabled during normal radar operation.
This is the noise level that is assumed when simulated
I and Q data are injected into
RVP900 with the LSIMUL command. The noise level is measured relative to the power of a
full–scale complex ( I , Q ) sinusoid, and matches the levels shown on the slide pots of the
Ascope digital signal simulator.
Limits: –100dB ... 0dB
Noise level for simulated data: -50.0 dB
This question asks whether IF samples should be plotted with Nyquist flipping
(multiplication by +1,–1,+1,–1...).
If
YES
, the
Pr
and
Pb
plots modify their rendering of IF samples. In those menus, the text
(NyFlip)
appears in the plot text heading when sample flipping is being applied. Other plots
in these menus, such as spectra and LOG magnitude , are unaffected by the Nyquist flipping,
nor are any live parameters derived from the IF samples. Only the visual appearance of the
IF samples is affected.
Nyquist sign flip of plotted IF samples: NO
WSR98D Test Points
This question appears on systems configured with the WSR98D control panel for choosing
the signals output on the RVP-controlled test points. A value of
0 means no output. To save
driver power, set these to 0 if the test points are not in use.
Many of these signals are WSR98D triggers:
• Update signals are triggers used to control the timing of when the control panel
outputs are updated.
