Hi All I have created the TinySA Ultra Menu-Tree Chart in Landscape format. David issued it in portrait format not so easy to use. Kind regards Kurt

I would understand that this is not possible due to copyright limitations so as not to make it easy for cloners, but a TECHNICAL DESCRIPTION with simplified block diagram, like the one for TinySA

The charging circuit of tinySA ULTRA is designed for a 3.7V battery and will stop charging when the battery is charged to 4.2V. If you plug in a 3.8V lithium battery, you can only use about 80% of the

My question would be can the charging circuit in the TinySA handle the bigger battery?

If you mean AD8317 Logarithmic Detector.?The tinySA ultra does not have a discrete power detector. The power detector is inside the SI4468 IC, after the selectable resolution bandwidth filter. The

I meant inside tinis ultra.

Why can't I use the ad8317 logarithmic amplifier IC for calibration?

Martin, thanks for the clarification. Erik, you specified the threshold very precisely. 6.22mVp-p (-40dBm), actually displayed as -39dBm: Single spikes are visible and indicates a red AM. 5.09mVp-p

I mostly try to use it for Phase Noise measurements of my SHF oscillators. i2NDT Claudio

Try to keep the input signal below -40dBm This may solve the problem with the spikes -- For more info on the tinySA go to https://tinysa.org/wiki/

The Tiny SA is only specified for frequencies >100 kHz. I notice the sweep is from 3 kHz to 103 kHz. I'm surprised you have been able to obtain a trace that looks anything as good as the ones you

Hello Erik, you're absolutely right. I have periodic access to the HP3588A spectrum analyzer, on which I tested my HP3314A function generator. This 3314A served as a source in previous experiments.

He is measuring the maxhold of a frequency sweep to try to see the flatness of the level measurement over frequency -- For more info on the tinySA go to https://tinysa.org/wiki/

The correction tables are generic for all same model tinySA and may improve over time. Unless you have created your own correction tables, you should never need to save/restore them over a FW update

What are the characteristics of the input signal? -- For more info on the tinySA go to https://tinysa.org/wiki/

Depth error is a warning that with the currently requested output levels there is insufficient headroom to perform the requested AM modulation. The device is not faulty but you are running into a

Hello, I don't have a clue what you try to measure or demonstrate. I can't identify any signal. Can you please tell us what signal you measure and what you expect? All the Best, Isidro Am 04.03.2023

The measurements continued. 1 swiping cycle of source took 1000 seconds. Accumulated 4 cycles:

Thank you. I seem to have missed this thread. There was a question on correction. Is it worth using the previously recorded correction factors in the new firmware?
