Automation & Device Test Plans

Multi-Instrument offers huge benefits from automation and the DTPs.

I'm hoping to ask a bunch of questions and also provide the DTPs I've been working on.

Would a new subtopic under Multi-Instrument be useful? Perhaps called Automation and DTPs?

Ta!

Speaker Monitoring

Doing audio repair and maintenance work it is very useful to have a 'levelled' speaker feed (ie agc applied so that there is always a residual noise) that allows one to hear what is going on is very useful. With old-skool N&Ds one could listen post-notch (no so easy with FFTs...) and easily hear ...

Re: Whish list

* It would be great if the UoM dBFS was available for all measurements (generator and input).
* Being able to do CHK comparisons using dBFS and relative dB units would be very useful.
* Within DTP the use of the generic term "V" isn't intuitive (easily mistaken for RMS etc). As used currently, 'Vpk ...

Sig Gen: Deterministic Units

Hi,

Suggest the signal generator's output setting dialogue boxes have the current units indication (V) changed to (VPK) so as to be specific.

dBFS Reading in Spectrum Analyzer & Noise Floor Hopping

I've a Dante audio interface (Sonifex DIO05) that has +18dBu full-scale input and output (ie FS = 6.1VRMS, or 8.63VPK, or 15.8dBV).

I'm seeing two odd problems (almost certainly PBKAC):
Question 1:
At full-scale output (0dBFS) the spectrum analyzer is showing the fundamental as being approx ...
