Re: AWG output amplitude

Hi,

Thanks for the answer!

In fact, I don't use the termination, but I connect the output of the generator to the transducer having 50Ohm input impedance. Do I understand right, that in this case the amplitude of the (RF) signal is the same as with a 50Ohm termination?

Sincerely,

Raman

AWG output amplitude

In PicoScope 5200 series AWG the output impedance is specified at 50 Ohm. However, I can measure the correct signal amplitude only when the output has a high-impedance termination. Is the amplitude specified for 50 Ohm or rather for 1 MOhm?

PS5203 AWG in "shots" mode

Hi,

Is it normal, that the generator produces a non-zero DC offset at the end of the waveform cycle in external trigger mode?

Re: Maximum output frequency of AWG

Thanks for the answer! So, it seems to be straightforward to generate sine waves up to 40MHz without loosing amplitude - higher harmonics will be damped by the amplifier. One could still add a lowpass filter to suppress them completely. By the way, specification for the amplitude is +/-2V: does it m...

Re: Maximum output frequency of AWG

Well, I think it just because you want to have enough points for your sine wave.
But one could increase the maximum frequency by putting an analog lowpass filter at the output. Is there one already in your AWG? If not, do you think it's possible to add one at the output?

Maximum output frequency of AWG

Why is the maximum output frequency of AWGs is limited to 20MHz if there are 125MS/s and 200MS/s available in 5000 and 6000 series, respectively?
