attila Posted October 23, 2018 Share Posted October 23, 2018 Hi @NYSD Here you can find WaveForms v3.8.18 with such options:https://forum.digilentinc.com/topic/8908-waveforms-beta-download/ Link to comment Share on other sites More sharing options...
NYSD Posted October 26, 2018 Author Share Posted October 26, 2018 yes. other sound device is compatible 16 or 24bit. I have AD2 and MOTU 896mk3(24bit 192kHz) but THD need sample rate too. sound device has the upper limit usually up to 192 k it is difficult...

attila Posted October 26, 2018 Share Posted October 26, 2018 Hi @NYSD You could try using the Sound Card device with WaveForms. The resolution, frequency, bandwidth, flatness... depend on the audio IO of your PC/laptop. Link to comment Share on other sites More sharing options...
NYSD Posted October 25, 2018 Author Share Posted October 25, 2018 I see! thank you! Link to comment Share on other sites More sharing options...
attila Posted October 25, 2018 Share Posted October 25, 2018 Hi @NYSD You can use the custom plots for such. Here for in Custom One plot the gain in shown in dB with "20*log10(Gain)" and in Custom Two the THD in % as "100*THD" Link to comment Share on other sites More sharing options...
NYSD Posted October 25, 2018 Author Share Posted October 25, 2018 Hi I checked new version. it's great!! if possible, Can you separate magnitude and THD? because "magnitude" with dB,THD with "%" or I would like to have two Y axes in the same table. ex, left Y1=magnitude dB, right Y2= THD % sorry for many order,,, Link to comment Share on other sites More sharing options...
NYSD Posted October 24, 2018 Author Share Posted October 24, 2018 Thank you!! I will check. Link to comment Share on other sites More sharing options...

NYSD Posted October 24, 2018 Author Share Posted October 24, 2018 awesome!!! I'm using Mac. pls add Mac version,,, and THD need more bitrate. so when AD3 (16~24bit?) comes, I will definitely buy it! Link to comment Share on other sites More sharing options...
fpliuzzi Posted October 23, 2018 Share Posted October 23, 2018 Thanks you very much for this new feature in WaveForms v3.8.18. This is really an excellent addition to an already full featured piece of software. Link to comment Share on other sites More sharing options...

NYSD Posted October 18, 2018 Author Share Posted October 18, 2018 Great!! I tried ver 3.8.17. I can measure THD with network analyzer!! but I want to see THD in percent(ex.0.1%...). so I want to change the y axis to logarithmic display... and If possible, I would like to see THD, 2nd, 3rd, 4th, in the same table. like REW app. Link to comment Share on other sites More sharing options...
NYSD Posted October 3, 2017 Author Share Posted October 3, 2017 hello. yes I use FRA and analog audio suite with windows. but I want to use mac without windows or some emulator... Link to comment Share on other sites More sharing options...
HILO Posted October 1, 2017 Share Posted October 1, 2017 Try this. FRAplus http://www.za.ztv.ne.jp/kygbncjy/tubeamp/FRAplus/FRAplus_intro.htm Download "bbs" http://amp.umetech.com/ariq/joyful.cgi Link to comment Share on other sites More sharing options...
NYSD Posted September 28, 2017 Author Share Posted September 28, 2017 Hi I want to see logarithmic freq plot,,, Link to comment Share on other sites More sharing options...
attila Posted September 28, 2017 Share Posted September 28, 2017 Hi @NYSD The Network Analyzer provides only magnitude and phase of the peak frequency step. THD or other measurements are available only from the Spectrum tool. In the following post you can find logarithmic step: Link to comment Share on other sites More sharing options...
NYSD Posted September 28, 2017 Author Share Posted September 28, 2017 Hi @attila Yes I saw and tried. But frequency is linear and if I can with network analyzer(with magnitude, phase), it is convenience... Can I measure at network analyzer as custom one?
