Check balanced or unbalanced audio en see clipping

Instruments HPS140 Handheld Pocket Oscilloscope
1

Hi there,

I’ve found the HPS140 and saw a demo on Youtube, very impressive.
I’m looking for device that can help me out on a project in 3rd world country. I need to see if:

  1. Analogue audio output is balanced/unbalanced 0,3Volt vs 1,2 Volt
  2. To see if the audio is clipping (too loud), so a little record function of 1 sec or so.

Could this device help me out on this one, or do I need something else?

add1) I know I can check the manual on a device to check this. But I like to have a reference.
add2) I can check it with a headset, but if you can show it visual to me and the customer… it’s more powerful.

Thanks in advance,

Albert

No problem to show clipping, however, how would determine if a signal is balanced or not, with a single channel scope?

Hi Vel147,

Thanks for your answer.
I’m not too much into audio, more into ICT. What I see here in Suriname that they don’t have too much knowing about what they are doing in the lokal TV industry. And I saw they connected balanced straight to unbalanced input with a TRS connector on a Panasonic audio mixer. What I want is to see on a monitor/oscilloscope what the exact levels are as balanced = +4dbU and unbalanced -10dBV And to show them if they are doing things right or wrong and can support them with graphs.

A better option would be the: PCSU1000, but that is 3x times the price of the HPS140.

Yours sincerely,

Albert

It is no problem to see voltage level differences.

You might want to look at the PCSGU250.
