1. Since it appears that a significant amount of data is kept within chanalyzer when it is running, ie. we are able to see "back in time" up to -17 hours. It would be very useful to be able to save and reload the current Data as a file. So that if we were NOT in the record mode and a significant event happens, a record could be preserved other than a screen capture.

(SAVE CURRENT DATA tagged with Date Time filename and

LOAD ARCHIVED DATA[an off line mode])



2.The logical offshoot of having this capability would be to enhance it's usefulness with a set of analytical tools. One such capability, although somewhat more difficult to implement, is the scrolling back through the data in ALL Time Scales. This allows for close examination of the characteristics of past events after they have scrolled off of the top of the Waterfall Spectrum display. This scroll back function would be equally useful in the on line capture mode as well.



Possible suggested implementations: A scroll bar or centering a time vertically when the left time values are selected.



More to follow.....

Thanks. That is a feature that we are working on. Chanalyzer will
always be recording to a buffer (like a Digital Video Recorder for
television). You will have the ability to move anywhere along the time
axis in the buffer.



We will also be adding markers, and the ability to save a section of a recording, as delimited by markers.



We are also adding the ability to load a file in the current window (currently you must open a new window).

Sorry if this is off-topic, but I received an e-mail from Metageek about Channelizer 3.4 stating "Chanalyzer 3.4 now calculates the average using power (mW) instead of amplitude (dBm). This provides a more accurate average amplitude value."

Since mW and dBm are merely units of measurement, I disagree with the last statement about whether average or peak powers are displayed somehow translates to "a more accurate amplitude value"-- even if the display is rescaled from a logaritmic display (dBm) to a linear display for mW--
And, since the WiSpy isn't directly connected to a transmission *source*, mW is pretty meaningless from a reciver's perspective, since a reciever doesn't "care" about power, but rather, "cares" about field intensity, so uV/m (microvolts per meter) would make more sense than mW--but I am digressing.

What I am really concerned anout is whether a dBm power display is still available. Using dBm is far more useful from a professional perspective than mW, so, if the feature is not toggleable between dBm (with a logarithmic scale) and mW (with a linear scale), can you patch 3.4 so that it is? Or at least offer 3.4a and 3.4 b with the respective features?

I am reluctant to even download 3.4, as I don't want to lose 3.3 until I know that I will not be losing a feature that I rely upon (and Channelyzer would become very unweildly for me to continue using without said feature).

Please prioritize this request (or, tell me not to worry because Channelyzer 3.4 can still display dBm)...

Thanks!

Our apologies for the poor choice of wording. Chanalyzer still displays in dBm and not mW. In fact it is now more accurate. Before we were taking an average of the dBm values, which is a logarithmic scale. This will give you an average amplitude, but doesn't reflect the average power on the frequency. By translating each reading to power and then taking an average of the power, Chan 3.4 provides a more accurate measurement of the power on each frequency.
