Sampling Frequency

[sychu]

Hello,

 

1. I'm just wondering if I can expect to get time sequence which has 10ns interval (ADC fs=100MHz) when I measure the Analog input from my circuit. (AD, AD2)

2. And because of 16k samples buffer, I only can measure(capture or save data) during 0.16msec (1/100MHz*16k).  Is there any way to increase the number of samples to save?

3. Can I change the sampling frequency also?

 

 

 

 

Best regards,

Sung

Hi @sychu,

I am not an a very experience user of the Analog Discovery so I am tagging the engineer that will be able to give you the best answers to your questions( @attila). Also Here and here are some great reference material for the analog discovery specifications. And here is the Waveforms 2015 reference manual.

thank you,

Jon

Hello,

For Repeated, scan Screen and Shift the frequency is adjusted based on time base. Eventually you can change the sample rate under time settings.
At high sample rate it can capture 16k samples.
At lower rates (<1-2MHz) you can use the Record mode to acquire more samples.
