Iv'e set up the EVM for a Flat top Frequency Sweep per SAU160a.pdf section 6.2 also see data sheet LMX2492-q1.pdf section 9.2.4.
The Board is power and the voltages appear at all test points and all parts for the high frequency VCO are populated. (can add a resistor to Fast lock pin).
Code Loader4 appears to download the configuration file to the IC, see flags and leds toggle as requested.
Probe the Charge pump output (see Test point) appear constant at low level but the sweep flag appear to work. The VCO output appears to be stuck at 8.9GHz and is not sweeping per App note.
When I enable three Fast Lock bits the VCO the Charge Pump output appears to non-linear ramps up from 0 to .330V and reset back to zero and repeats the ramp.
Can you help me.
Thank you.
