Part Number: LMX2572EVM

Hi,

I have LMX2572EVM with reference pro. My goal is to generate a frequency sweep between 1560 MHz and 1590 MHz in 1 MHz steps on the RFoutAP output within 100microseconds.I have given external ramp clock of 200khz as input on RampCLK_TP on LMX2572EVM . 

I am not able to generate ramp according to my requirement .The output ramp is generated from 1577 MHz to 1590 MHz .

    Hello Abishek, 
    Given you want a step size of 1MHz you need RAMP0/1 to be +/-4 MHz because your output channel divider value is 4 thus the actual step size is 4MHz / 4 = 1MHz. 

    Currently your step size is 1MHz / 4 = 250kHz 
    Try the following:
