OK, Ill be the first....

These are 5 bugs that I am reasonably certain of.  First one is real dangerous and we are working on it first! 

6.7.10.25          TDS 6.7.8.0

 

1)      When you select sample rate of 96, any ETC you will make is wrong by 23 ms or so.  Also sometimes switching the sample rate causes the output voltage to go to max even though the screen indicates that it has not changed!

2)      Doing ETC overlays causes error messages usually after the 3rd or 4th time but apparently only does it when actually making measurements.  I have not seen it just opening files.

3)      When you save a TDS frequency sweep the options are ASCII or Freq/Phase/Amplitude.  Saving as ASCII actually saves the file as a .tds

4)      When you use Steve’s trick of setting to getting more time on the screen for real long ETCs for reverb measurements, involving showing negative time, the measurement looks believable, but the cursor only works on the right hand side of the screen rendering the measurement useless.

5)      When you select “put new data into new window” it only stays “true” for one measurement then reverts to “replace all data with new data”

Any one else seen these?

As soon as they are fixed I will post the update here, on the website and on the list serve.

One other bug I'll mention is that of not being able to set the output voltage.  When directly typing in the voltage, and upon exiting the field, the value is changed slightly.  In talking to Steve M. at a trade show, it seems that the voltage value updates the voltage level (dB), which is rounded to the nearest one-tenth dB.  The voltage value is then updated with the rounded value from the voltage level field.  I guess were just lucky that it stops there & isn't an inifinite loop.

 

It would seem that increasing the internal accuracy of the voltage level may minimize this problem.

 

BTW Core version is 6.7.10.25, TDS 6.7.8.0

core: 6.7.10.25               TDS: 6.7.8.0

I have problem with STI measurement. When results displays on screen I can see table, also I can click extended table, but when clicking Display -> Graph, I can see only blank (blue) graph space with no graph lines - see attachment.

Core: 6.8.5.14   TDS: 6.7.8.0

I am having a problem with the signal generator dialog box.  First off, I really like the new layout in the latest core update, very useful to have everything on one page.  I am doing testing of speakers in an anechoic chamber.  I use an Audio Precision analyzer to measure the output voltage at the speaker terminals, so I need accurate control of the output level, down to the tenth of a dB. 

Something in the entry box for the output level is frustrating.  I cannot enter decimals.  If I want to have the output be, say, -25.7 dB, I type '-25.7', but the decimal doesn't register, giving me -257, which defaults back to -100!  Right under it, the volts entry box, I can't enter any decimal, so every number tends to be entered huge and defaults back to 8 volts.  I get the feeling the 'auto entry on when you hit the TAB key' has something to do with this.

One other oddity - often I have several overlaying graphs and I want to change the legend for each curve.  I still haven't figured it out totally, but if I have three curves, I click on the middle one, then when I do a 'File' 'Description' to change the curve name, the LAST curve listed is the one I end up editing.  If I want them in a certain order (for instance, fundamental, 2nd harmonic, then 3rd harmonic for HTR curves), good luck, I just click around until I get them listed in the legend in the order I want.

I know these are small items, but they make the program really hard to use sometimes.  I just want the program to do what I want it to!!!  Steve, can you fix these please?

Thanks for posting these bugs.  I will look in to it as soon as possible!
