Hi. I have a question about setting of dc1762.
I want to send a sine wave to the dc1762 from the power supply and then to the PC via the dc890b(FPGA board).
But I have a problem that ENOB can not raise to 16.
My settings are below
power supply: 5V
Signal generator
CH1 for analog input: 9MHz sine wave, amplitude: 1.5Vpp, 0V offset
CH2 for clock : 100MHz Square wave (3V high, 0V min, single-ended)
DC1762 board
Parallel/serial :serial
Duty cycle stabilizer: disable
SHDN: disable
NAP: disable
LVDS/CMOS: disable
After checking the results on PC with pscope, it was like the picture below.
ENOB is 1.56bits
I would really appreciate it if you could help.
