Hameg oscilloscope setting

There are a couple of things that could be wrong:

Soldering errors, if you are seeing an output that is 0, try resoldering the resistor.
Your oscilloscope might not be sampling at a high enough frequency, this means that it might miss the current draw spikes that occur when the radio is active. In addition the oscilloscope might also do averaging to smooth the results, try turning off averaging if you can find an option for this.

As for settings on your oscilloscope I cannot be of any help.

Hi Karlsen,

Thanks for your answer.

I did try using Differential Mode (using Add and Inv) not X-y.And I set it to AC for both signals.

I keep getting the same signal for any program that runs on nrf51dk the signal doesnt change at all :(

I dont know where I am going wrong. The probes are connected to the nrf measurement points as directed in the manual.

Do you have any idea wher eI could be going wrong?

Hi,

While I am not qualified to answer specific questions about your oscilloscope(please refer to Rohde&Schwarz(Hameg) for this) I can try to give a partial answer.

Connect two probes to channel 1 and channel 2 of your oscilloscope
Connect the probes to both sides of the 10ohm resistor, make sure that you connect both probes to ground
Set the oscilloscope to X-Y mode(differential mode)

As for settings, please refer to the manual, or contact the producer directly.

Best regards,

Øyvind
