- Go to RF Parameters tab (cf. Fig. 17 in the user guide) o *Leave the Selector Field "Front End" unchanged at 24, 60 or 122GHz, since it will not influence the further measurement. o *Set the VCO devider to 128 o *Insert a Bandwidth (MHz) of 40'000 MHz as start value and increase later to the maximum bandwidth used o *Set the Base frequency (MHz) to 289'000 MHz. - Go to BB Processing tab o Adjust ADC clock divider to around 1-2ms or more (please watch the DC peaks) o Adjust Number of samples to 1024 or more o Adjust FFT size to 1024

== '''EvalKit Easy – Operation with Front End TRA_300_030 in wide-band modus''' mode ==
Since the EvalKit Easy is not recognizing radar front ends with wide band-operation capability a manual adaptation may become necessary.
== Cable Connection ==
For the power supply to the front end a separate connection is required. The red power cable connects the 5V pin of the Front End board as shown in Fig. 1 with the pin E5V of the Easy board.
== Software Start ==
To launch the software evaluation platform please follow this routine:
== Parameter Setting ==
Whatever measurement graph you receive, please continue with the following steps:
Go to BB Processing tab
*Adjust ADC clock divider to around 1-2ms or more (please watch the DC peaks)
*Adjust Number of samples to 1024 or more
*Adjust FFT size to 1024
After you have performed all steps you should get an output similar to the one in Fig. 4.

== Return to Operation with automatic recognition of Radar Front Ends ==
For operation of SiRad Easy radar front ends with automatic recognition exchange the front end boards as previously used and restart operation.
