Other Parts Discussed in Thread: LMX2572
we are looking into the freq.ramp funciton of LMX2572.
We have a freq. spann of 1045MHz - 1020MHz
Do you have any instructions how to do this sweep with EVM and TICS pro.
Thanks

Hi Bjom,
Have you checked the EVM user's guide? There are couples of ramp examples.
Your frequency span at the output is 25MHz, that means the VCO frequency span is 100MHz. So you cannot do calibration-free automatic ramping. In other words, you cannot get linear frequency ramp, a couple of frequency calibrations is required during ramp.
To understand the concept and limitation of frequency ramp, read the following section in the datasheet.
7.3.13 Ramping Function
8.1.7.1 Manual Ramping Mode
8.1.7.2 Automatic Ramping Mode
