10:27 < kanzure> beep boop
10:43 < archels> frack. that Rigol oscilloscope that I wanted to buy is sold out until at least Jan 1st at three major distributors
10:44 < chris_99> darn, which one did you want
10:45 < archels> the DS1054Z
10:46 < archels> the 74 was in stock, but I'm not paying €180 extra for a software option to unlock 20 extra MHz of bandwidth
10:46 < chris_99> oh 4 channel cool
10:46 < chris_99> i've got the 2 channel, 50MHz one, that can be upgraded to 100MHz via firmware
10:47 < archels> ah yeah, this one too apparently
10:47 < chris_99> nice

11:09 < nmz787> archels: get the Z series
11:09 < nmz787> i have it
11:09 < nmz787> and did the unlock from eevblog
11:10 < nmz787> oh, wait, the 1054z is new?
11:15 < nmz787> ah, ok, the 50MHz option doesn't have an option for a sig-gen
11:15 < nmz787> I guess I have the 1074Z-S
11:16 < nmz787> I was a bit upset that I missed the spec that said the square wave generation bandwidth limit was about half of the analog sine generation
11:17 < nmz787> which makes sense if it's coming from an analog circuit, but why not switch to a GPIO based generator or something digital for square wave generation
11:23 < tallakahath> I've been hilighted

12:14 < andytoshi> kanzure: are you aware of any archives of sheet music?
12:15 < archels> nmz787: you're saying, get the -S option?
12:17 < archels> random books http://avaxhm.com/ebooks
12:20 -!- delinquentme [~dingo@74.61.157.78] has joined ##hplusroadmap
12:26 < nmz787> archels: unless you have a another sig-gen that you might use that's better
12:27 < nmz787> archels: it is nice that it is in the same case/enclosure.... but I didn't read up on sig-gens before buying, I just figured I would be pissed someday when I needed a sig-gen while probing some circuit
12:27 < nmz787> so there could be better values out there
12:28 < archels> mmm yeah
12:28 < nmz787> just watched the eevblog teardown of the 1052Z
12:28 < archels> I passed up on a pretty good oldschool HP signal gen today at a good price
12:28 < nmz787> pretty neat to watch him rev-engineer the analog front end
12:28 < archels> a friend recommended to wait for the guy behind HackRF to make the signal generator version thereof
12:29 < nmz787> is he planning that?
12:29 < archels> probably half as expensive and infinitely more versatile
12:29 < archels> yeah, apparently
12:29 < nmz787> you can get the MCU that it uses for $20-$25 as a demo board
12:29 < nmz787> i thought he was working on daisho now
12:29 < nmz787> well actually that dev board has a bit better device, with an 80MSPS ADC
12:30 < nmz787> the LPC-Link 2
12:30 < nmz787> which is a usb3 i/o thing
12:30 < archels> the thing is, I don't want any of this to turn into a project
12:30 < nmz787> (daisho)
12:30 < archels> I want something that I can just plug and plug and that just works
12:31 < archels> plug and play*
12:31 < nmz787> yeah, that's why i just spent the extra $ on the added sig-gen in the rigol
12:31 < archels> right-o
12:31 < nmz787> also i noticed that when you have the sig-gen on and all 4 channels the controls are a  bit laggy
12:31 < nmz787> so that is another vote for a separate gen
12:32 < nmz787> other than that, the unit has been pretty great for what I want
12:32 < chris_99> i'd go for the bladerf over the hackrf
12:32 < nmz787> i demoed a $20k USD scope from Agilent prior to demoing the Rigol (higher end than Z and also the Z)
12:33 < nmz787> and it was comparable on memory
12:33 < nmz787> chris_99: I had the opposite opinion when I last checked
12:33 < nmz787> they were both at defcon
12:33 < nmz787> i can't remember why i thought that
12:33 < chris_99> the half-duplex puts me off hackrf
12:34 < nmz787> whatcha mean?
12:34 < nmz787> i thought it was only a receiver
12:34 < nmz787> or you mean the fact that it has to buffer signals?
12:34 < superkuh> Nope. Transmit 10-6000 MHz too.
12:34 < nmz787> rather than streaming them
12:34  * superkuh has one.
12:34 < nmz787> oh
12:35 < nmz787> cool
12:35 < superkuh> I mostly use it as a transmitter and receive with rtlsdr.
12:35 < superkuh> But soon I'll have an airspy too. :D
12:35 < chris_99> http://www.taylorkillian.com/2013/08/sdr-showdown-hackrf-vs-bladerf-vs-usrp.html
12:36 < nmz787> on another note, this seems OK, haven't tried it yet on the arduino mega files https://github.com/DanChianucci/Eagle2Kicad

12:36 < archels> 10 MHz lower frequency limit though, so not so useful as a benchtop function generator
12:36 < superkuh> Interesting side note, for automated testing of Airspy (Rx) boards at the factory in China prog sent a HackRF with modified firmware.
12:37 < nmz787> chris_99: i guess you just need two hackrf's!
12:37 < chris_99> which would be > than a bladerf
12:38 < nmz787> :/
12:38 < superkuh> Right now the osmosdr source for GNU Radio doesn't seem to support on the fly switching of Rx/Tx either. But I expect that to be fixed.
12:38 < superkuh> Er, for HackRF.

12:48 < nmz787> chris_99: that data is a bit old, it doesn't compare against hackrf one
12:49 < chris_99> what specifically?
12:50 < chris_99> looks like the hackrf 1 is still 20Msps, but starts @ 10MHz
12:52 -!- CheckDavid [uid14990@gateway/web/irccloud.com/x-byshxiylsazgaqxn] has joined ##hplusroadmap
12:52 < nmz787> literally just saying it wasn't listed in the comparison
12:53 < nmz787> seems the main advantage is it's completely open, and that it relies more on C than HDL
12:53 < nmz787> but I guess this all depends on what you want things for
12:58 < chris_99> are they both not open?
