7.1.14
Bandwidth Reduction
This parameter is used in continuous mode only, when pre-scan and frequency adapt is
activated.
This value needs to be smaller or equal to the bandwidth determined by the range cell
depth parameter.
If the frequency pre-scan post-processing software cannot find a free gap for the desired
sweep bandwidth, then the sweep bandwidth will automatically be reduced step by step,
until a useful free gap in the frequency band is found, or until the defined value for this
parameter is reached. The next measurement will use the determined sweep bandwidth.
As such a change will alter the range cell depth, the amount of range cells will
automatically be readjusted at the same time to maintain the same maximum range.
Note that the given steps are fixed in the post-processing software. If different values are
desired, contact the manufacturer, because modifying the WeraDesk web page only will
not work. You might end up with a few very large range cells only.
7.1.15
Working Frequency
Please enter the Center Working Frequency into this field. The format is [nn.nnn] MHz.
This value is used for single measurements and for continuous measurements if the
"Adapt Frequency" option of the frequency pre-scan is disabled.
7.1.16
Range Cell Depth
Ensure that the required bandwidth is available at the selected "Working Frequency"
(which is the center frequency).
7.1.17
Samples per Data Run
The actual length of the time series is calculated from the Samples per Data Run and
Chirp Length fields.
The value 13312 is intended for permanent mode. In permanent mode the amount of
possible samples per data run will be re-calculated by taking the cycle repetition time and
time for the optional frequency pre-scan and DPT into account. If there is not enough time
for the selected amount of samples, the samples will be reduced to a value that fits and
can be divided by 128. In this case a warning will be displayed to notify the user.
