The Radar meters do not indicate upwards of 40dB rolloff at the end of the sweep, so it's gotta be something with the program. Either there is something very wrong with my radar or I just don't understand this program. Most channels are rolling off dramatically around 14K. The difference here is that instead of "Import impulse response" I used "Import Field Recording"Īgain though, this can't quite be right.

So, I did this, sweeping all 24 channels of my Radar (actually 23, since the stimulus was on one track. So, in reading the fuzzmeasure manual, for this sort of thing, it recommends exporting a stimulus signal (sweep) and then 'import field recording.' When importing a field recording, you have to provide a link to the stimulus signal that you used, and then the link to the field recording that you're importing. So getting an analog signal in and out is easy.Ħ Do you have a connection with this software? This is what the OP is trying to measure. It is also a very good level meter.Īnd its only an example, the OP could buy an AP on Ebay too but its a bit more expensive!Ĥ The Radar has ADC's and DAC's. )Ħ Fuzzmeasure is a fine piece of software capable of doing accurate and high precision measurements.1 The strange graph taken from a reputable product.Ģ No, but I have seen a lot of other socalled measurement software.ģ Because it is very cheap for a peice of high quality equipment.

Also one that only gives you down to 0.1%HD which is extremely poor performance compared to what you can do with Fuzzmeasure and a modern audio interface if distortion is what you want to analyze.Ĥ Also it's a bit tricky to get the signal from a Heathkit tone generator into the computer in order to test a DAC.ĥ Even more tricky to analyse an ADC with the HP unless there's a new add on module with digital inputs. )įuzzmeasure is a fine piece of software capable of doing accurate and high precision measurements.ġ What do you base your critic of Fuzzmeasure on?Ģ Have you used it and/or are you familiar with the capabilities?ģ I'm a bit puzzled why you are recommending a dated distortion analyzer to someone wanting to do frequency response testing.

What do you base your critic of Fuzzmeasure on? Then a good oscillator, anything from Heathkit on up.Hi! HP and other brands are readily available on Ebay and cheap. If you are serious about measuring, buy some proper test gear. Second question is why use some peice of **** software you downloaded off the internet to try and do serious measurements? Their converters will do what they say they do. First question is, why? The Radar is a professional peice of gear from a reputable manufacturer.
