SignalScope Pro / Re: IOS 13 breaks Signal Scope Pro
« Last post by FaberAST on September 30, 2019, 12:09:50 PM »
The end of support for the legacy version of SignalScope Pro was announced in January of 2018. The final update was published in March, 2018, and the app was removed from sale on the App Store in July, 2018.
Faber Acoustical Releases SignalScope X for iOS as a Free Download

Current alternatives:

Free Download + Subscription:
SignalScope X

Perpetual License
SignalScope Pro 2018
SignalScope Advanced 2018

The Advanced Tool Set subscription in SignalScope X and SignalScope Advanced 2018 most closely match the functionality of the old SignalScope Pro.

Subscriptions are recommended for anyone who plans to always run SignalScope on the latest version of iOS.
Perpetual license versions are recommended for those who need to run SignalScope as a dedicated instrument. This means on a device dedicated for measurement/analysis/data acquisition that can continue to serve its purpose indefinitely without the need to upgrade iOS. (Of course, upgrading iOS is fine in this case, as long as it is supported by the perpetual license version of the app.)

Still broken on 13.1 with a fresh download of the app.  So I'm guessing support for this app has ended?
SignalScope Pro / IOS 13 breaks Signal Scope Pro

At least on my phone 6S.  I rolled back to 12.4.1.  I know support for this product is limited, but It would be nice if it still worked on current version of IOS seeing that it does all I need it to do, is not subscription based, and was reasonably priced when I purchased it (unlike the new offerings).
SignalScope / MOVED: Triggering

SignalScope / Re: Triggering

OK.  I'm going to answer my own question: You have to select a trigger in the Display tab.
SignalScope / Triggering

This is a very basic question, but here it goes.  I am using SignalScope to display an audio waveform.  In this case 440 Hz sine wave.  The display shows an amplitude of about 1 FS, with the waveform bouncing all over the place for lack of re-triggering the scope scan.  Now, I have enabled triggering, created a trigger on the same input, set the threshold to 10 mFS, trigger on positive, auto mode.  Waveform still bouncing all over the place.  I have tried just about every combination of mode, threshold, and slope to not avail.  What am I missing?
SoundMeter / Re: Calibrate MicW i437L
« Last post by FaberAST on October 01, 2018, 06:29:07 PM »
According to MicW's current instructions, you should set the device gain to Mid and the device units to FS. Then, set the sensitivity for the input channel according to the value that was written on the sheet that came with your i437L (e.g. 19.9 Pa/FS). (Make sure input channel units are set to Pa.)

We just tested this, today, with an iPhone X and XS Max, and the results agreed within 0.1 dB of a 94 dB field calibrator on both devices.

Keep in mind that the sensitivity given by MicW is valid for the Mid gain setting, only. If you want to measure higher or lower SPLs which would require Low or High gain, respectively, you would need to perform a calibration at the chosen gain.

Hi mgolden,

just bought the same mic and I'm curious to know if you ever came around to check your calibration?

SignalScope / Re: Frequency Measurement
« Last post by FaberAST on September 25, 2018, 07:02:25 PM »
It's true that there are no physical knobs for adjusting the Oscilloscope display.

Perhaps, you have already found that if you look in the Display tab of the drawer on the bottom side of the Oscilloscope window, you'll see the software controls for adjusting the amplitude (Vert) and time (Horz) scale of the scope.

Frequency measurements can be made with the Oscilloscope, using the dual data cursors, but it would be easier to measure frequencies with the FFT Analyzer. However, if you need very fine precision, it may be better to use the Oscilloscope.
SignalScope / Frequency Measurement

I am finding doing frequency measurements with SignalScope to be difficult.  It has to be done visually  and by hand, and there are no physical knobs to tweak the time axis like in a hardware scope.

Ideally the fundamental frequency would be available somewhere.  Am I missing something?
