2208 Sweep Measurement

Post by Yostin »

Hello,

Forgive me if this is a simple problem but I am a novice.
I have just bought a 2208 and have setup the scope to do a sweep test as seen in the following video

In my measurements I see a high peak at the start of the X axis that doesn't seem normal. I just have the probes connected together from GEN to channel A.

Is this expected?

Hi

When performing a FFT on a signal to transform it from time domain to frequency domain as happens for the Spectrum Mode in PicoScope 6, you should get a peak at 0 Hz which corresponds to the DC component of the signal.

Thanks for the reply.

What is an acceptable level of DC offset from the GEN output of my Picoscope?
