John Mulcahy's latest activity
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.Builds updated today (beta 103) with these changes: Added: Show a warning if the Analysis preferences IR truncation setting is too... -
John Mulcahy replied to the thread Group by output.There's an option to prefix the measurement name with the output, and on overlay graphs an option to sort the measurements...
-
John Mulcahy replied to the thread Feature Request: Make "stop at" option in the RTA unconditional, and allow numbers starting from 1.That isn't possible for live data as initial samples are discarded to allow for buffers to flush through. For processing files set the...
-
John Mulcahy replied to the thread Testing electrolytic cap ESR with REW?.You can do an impedance measurement then fit a component model to get an equivalent circuit. The graph will directly read dissipation...

John Mulcahy replied to the thread IMD Measurements: "Generator" vs "Input" Level Discrepancy.There are two things to consider. Firstly, the reference for IMD distortion figures. That varies depending on the test signal, for DIN...

John Mulcahy replied to the thread IMD Measurements: "Generator" vs "Input" Level Discrepancy.No, the noise floor measurements are very similar for me using the dBr axis and measuring using the current V5.40 build, using either...
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.By "remove" I mean deselect.
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.That's not something REW controls. If you are using a WASAPI Exclusive Java entry there may be some other application that has taken...
-
John Mulcahy replied to the thread REW Beta Release REW API beta releases.If you remove a measurement using the selectors on the left the number of entries in the legend changes. That may change the size of the...
-
John Mulcahy replied to the thread Feature request: Possibility to select Yamaha AVRs in the EQ window.What about the configurable equaliser?
-
John Mulcahy replied to the thread Am I using REW RTA to measure SNR correctly?.With the axis on dBu the figure could be used directly since your test signal is 0 dBu, but note that the SNR definition excludes...
-
John Mulcahy replied to the thread Accuracy of harmonics amplitude in RTA.I wouldn't use a method that subtracted anything from the observed energy. REW is a little more conservative than it could be, I agree...
-
John Mulcahy replied to the thread Am I using REW RTA to measure SNR correctly?.REW's SNR figure is unweighted, and the N component excludes harmonic distortion. There is an A-weighted N+D figure that is the level of...
-
John Mulcahy replied to the thread Feature request: Saving and Recalling user Preferences.That's on the to-do list to look at for a future version.

John Mulcahy replied to the thread Accuracy of harmonics amplitude in RTA.If you are attempting to identify the noise floor then I'm afraid that becomes very problematic, since noise floors are rarely flat for...
