I am using AD6688-3000EBZ, ADS7-V2EBZ with ACE software.
I have some questions.
1. when no using DDC(Full band width mode, No DDC), the resolution of ADC is 7 bit. is that correct??
2. 915MHz (+10dBm Signal by using signal generator) is continuously applied to ADC A channel input.
the Setting : Sampling clock : 2.441 GHz DDC Mode ON (NCO Freq : 915MHz) , L = 4, M = 2, F = 1 N'=16, Line rate = 6.103Gbps, Decimation rate = 4.
But, the level of Fund Power is consistently changed.....
What is wrong with this....
Look at the pictures as below.
The test condition is fixed. not changed But Fund Power is consistently changed. (Picture 1 : -27dBFS Picture 2: -12dBFS)
3. When I start the ACE software, I can see the error message as below.
Actually, In the past, I used AD9208-3000EBZ with ACE Software.
But I could not see that message.
what is the problem?!
Thank you for ur help!!!
