Using a Datapack 1500 and Odyssey Delux 2.3 how do I tell if I am collecting digital or analog overalls?

Thanks,

I'm not too sure about what you mean here. The dataPAC 1500 is a 32bit digital box as far as I know. The options for set up include analog or digital filters which you select in Emonitor. I would assume you are collecting digital data at all times but I could be wrong. I haven't really thought about this before.

Ron.

Ron,

A digital overall collects data over a specified frequency range and an analog overall collects data over the full range of the analyzer. (At least it is that way with CSI equipment and I don't know why it would be different with IRD.)

Where in the set up menu are the filter options located?

What I'm really getting at is why it takes so long to dump data and it was suggested that maybe I am collecting analog overalls which would be much bigger than digital. It was all set up when I started doing this and I don't know how.

Thanks,

Danny

I think that you have to add new band filters to your Odyssey to tell the 1500 to take digital overalls, so if you haven't made new filters for this purpose you are taking analog (Setup/BandFilters/New). Therer is a complete description of how to do this in the release notes of the 1500 Ver. 5 op sys. Also try Odyssey Help/Datapac/Index and search for either digital filter or RSS filter. As far as the time it takes to load/unload I know what you mean, the Odyssey/1500(and the Enpac for that matter) combination is painfully slow. I don't think it is Odyssey because an old IRD 890 loads in the blink of an eye. Possibly the drivers? Be sure your comm port baud setting is 115200, that will speed things up a bunch if you are now set at 38400 or less.

Danny,

As dj says, you have to set that up in the filter. Go to one of your filters and right click, select edit filter. Down at the bottom is the "select data collector filter type".
If you select the RSS, then that filter will cause datapac to use the digital filter for every measurement that the the filter is used in. Check how many g's and ips filters you are using. change it in all of them, then you're set to go.
Call me if you have difficulty.

By the way, the omni pro is light years ahead of the serial cable. Probably the biggest reason you are seeing slow is the 2120, 2130 is collecting time waves only. The software is doing all the integration and math work. I think they have a processor to do it in the box if you want to see a spectrum in the fieled, but my understanding is they only store tw's.
The IRD instruments will store spectra because they are using hardware integration, instead of software. That is why each measurement is stored individually. You'll get used to it
Gives you time to look around at the equipment (that's what I tell myself).

Thanks for the tips Dave and DJ. That sounds like I can figure it out now that I have some direction.

Dave,

The 2120 stores spectra and twf data. I assume that it is user selectable, but I know mine stores both so I have never looked. It will store 1 meg of spectra, 1 meg of waveform and 1 meg of note data per route up to the size of your memory card. I have only filled mine up with spectral data and it isn't very hard to work around when it happens. I don't think I could ever put a meg of notes into that poor a typewriter.

Thanks again,

Danny

ps Dave, check out the post about the IRD Datapack cards

Under Route Management>Edit Existing Route>[select route]>Edit Route Parameters>Data Storage you can select how to store TWFs and FFTs.

Danny,

Check your data tables in Odyssesy, if the magnitude reading and band overall in the spectrum are the same, you probably have been storing digital overalls. In The Odyssey software Help under Datapac[Click help and scroll down until you find "Datapac" and click on it, then do a find for "RSS". In the selection box below you should see one listing for Measurement Filters...double-click it. It will show a window with a complete explanation of setting up filters specifically for the Datapac.

Danny,

In the new version of EMonitor software, under 'Setup' menu and 'Band Filter', if you try to create new filters, it gives three options viz None , Analog and RSS (digital) and any one of these options can be checked.

Setting Filter to 'None' makes data collection time to be longer which can be overcome by setting it to either Overall or Smart HP Filter type.

Thanks and Best Regards
