Small signal network analyzer and oscilloscope problem

[thoriam]

Hi

I want to use Analog discovery 2 on very small signal (100uV). In network analyzer I can set amplification for wavegen and set 100uV

But the generator is +/-5V with 14 bits so its not enough to generate it. Do i need external circuit like resistor divider or something?

Another question is in oscilloscope to change how many samples at what frequency you need to hit "auto set". Is it the way to change manually this frequency? Also specs show 30MHz, but waveforms shows 100Mhz

Why is that?

And last question the max bandwith of the osciloscope is for both channel or its just for one?

Hi @thoriam

Yes, you should use external resistor divider to reduce the amplitude.

 

The bandwidth is 30MHz, the sampling rate is up to 100MHz.
This is adjusted automatically based on time-base setting.
