content: I finally pulled the trigger and purchased this model scope and am in the processing of getting familiar with it.The firmware was updated to the latest (1.32) and I noticed that there is a Function Module called 'FFT - Standalone' that needsthe necessary module file(s) to enable it.I cannot seem to find any reference to this standalone mode in the documentation and the GW website shows no downloadable module for it.Evidently, Ver 1.30 introduced this feature.Can anyone shed some light on this feature and where the necessary module files may be downloaded?ThanksJim

content: I got the standalone FFT application through GW Instek's technical support. I de-installed it again though because I usually want to see the signal as well and the standalone module doesn't add any features.

content: Ok, I appreciate the information but I'm a bit confused-So, there are 3 flavors of FFT?With No Function Modules you get the standard Math version - Is this a dual display version?FD Mode - Dual Display FFTStandalone Mode - Standalone FFTSo what is the difference between the three? Is it just the way the data is presented?

content: Yes, standard is FFT + signals, dual mode where you have a big FFT area and a small signal area and finally the standalone where you have FFT only. These modes all have the same FFT features.I really wish GW Instek had made the enhanced FFT features from the MDO2000E series available (as a paid option) in the other GDS/MSO 2000E series. I don't see the added value of the MDO2000E series as a product by itself.

content: IIRC you need to register and login to see it in downloads.

content: I appreciate the responses.I did register on the GW site and saw the Function Mode for the Dual Display version but not the standalone. I believe nctnico mentioned that you have to ask technical support for the standalone version.It appears that both the dual and standalone can be installed at the same time but if so, is there a soft key way of switching between the two modes?

content: Does any of these allow viewing the FFT of an averaged signal?A related question I ran into today was the LA bus event table. I don't seem to be able to record more than about 100 events when watching the traffic from an MCU to an LCD. Is there a way to log more data?
