In this episode Shahriar reviews the new Tektronix AFG31000 Arbitrary Function Generator:
www.tek.com/signal-generator/...
The AFG31000 series with InstaView™ technology is the first high-performance AFG with built-in waveform generation applications, patented real-time wave monitoring, and a modern user interface. The instrument is capable of 2GS/s waveform generation up to 250MHz and 14-bits of vertical resolution. This review is organized as follows:
00:08 - Introductions
01:01 - Front panel, rear panel and instrument design
03:44 - Detailed teardown, analysis, architecture and components
17:30 - GUI overview and basic functions
20:25 - Broadband FM modulation experiments
23:55 - InstaView experiments with a non-linear impedance
35:38 - Equation editor, waveform builder and advance sequencing
51:21 - Concluding remarks

Excellent teardown of an amazing instrument. Thanks for sharing!

Very cool instrument. Thanks for the review.

Monumental learning curve for myself,thanks so much.

I like the coupling layout/design around the mounting holes on the PCB.

nice instrument by tek , and nice video (as usual ) i wish i can get this function generator alongside with that tek scope

@pigrew 4 года назад

Wow. At first I figured that an ARB generator review would be boring, but the instaView is a very unique feature to think about. Maybe you can use it as a 2-port VNA with an "app" download? This instrument has many possibilities.

@Thesignalpath 4 года назад

I have a felling more of these apps will come in the future.

@jorditribo94 4 года назад

They need to work more on that Instaview software. It is a shame that they could implement all the hardware capabilities and then they screwed it up with the UI.

@martinhodge921 4 года назад

The software on this instrument very much resembles that of the ancient Tek awg2021 I just refurbished. Basic Layout, labeling, functions, etc. This one just has much more.

After talking online with a tech from tek.com, I will be in touch with the design team relative to instituting your GUI suggestions. Good job. Bruce

@IxIVVI 4 года назад

Thank you for the video! That ground coupling is interesting - can you explain more about it? Really curious what's the matter with that.

@bfx8185 4 года назад

Would be nice to see internal HW differences between cheaper one and this hi performance one :)

@poldomalese 4 года назад

Thanks Shahriar. I'm still watching the video but maybe I can already ask a basic question: I see the DACs are 14 bits, whereas much less renowned brands today commonly offer 16 bits. How important is that for an AFG?!?

@campbellmorrison8540 4 года назад

If only I could afford one :)

@trickyrat483 4 года назад

Underdeveloped UI and no mouse and keyboard support. Seems to be a solution that forgot the very problem it was trying to overcome. And, tbh, I'd much prefer to do the waveform composition on a PC anyhow. Priced from £2k to £13k inc. VAT. Not so sure it justifies the pricing..

@BruceNitroxpro 4 года назад

According to you, you are being paid to do its work for free... Oh, you're NOT? And that repeats for each design? Oops.

@BruceNitroxpro 4 года назад

@MichaelKingsfordGray , Oh, please.

@TheRossiale 4 года назад

Please make a video about antenna polarization

@WillArtie 4 года назад

I would very much like to have one!

@MaicSalazarDiagnostics 3 года назад

Thank you for this great video. I am very interested in this tool. I like that you can create your on waveforms. Can you show that feature? I am looking to create cam and crank signals sine wave.

@tommihommi1 4 года назад

I'm just waiting for the first arb generator to come with the desmos app as the equation editor lol

@tommihommi1 4 года назад

@MichaelKingsfordGray desmos is a great open source graphing calculator/ equation editor/ math visualisation tool, and since it's open source, someone could use their GUI.

@Richardincancale 4 года назад

10:36 Why does the 10 bit / stage delay chip have an 11th stage that seems to feed back?

@WillArtie 4 года назад

Maybe to get longer delays?

@LaboussoleNano 6 месяцев назад

Hello, I am beginner in power electronics, Thanks a lot for the content. . I watched and read the DPT using AFG31000. When I download the datasheet I can't see the range of voltage generate by AFG31000, can you help me with the values. Thanks

@hushaby1 3 года назад

Can this model read currents from a sample/device and send to pc using usb?

@stevefriedl3983 4 года назад

Instrument signon message @ 17:35: "Keithley, a Tektronix company". Interesting.

@Thesignalpath 4 года назад

Keithley has been a Tektronix company for a while now. :)

@stevefriedl3983 4 года назад

@@Thesignalpath I know that, but this instrument is badged "Tektronix", not Keithley, unless I've missed something. Do they mix-or-match their branding?

@Thesignalpath 4 года назад

@@stevefriedl3983 Oh! Sorry, I misunderstood. It is possible that some part of the firmware was originally developed by Keithley. It does have some resemblance to their work.

@michaeleconomides4054 2 года назад

When I go to Run Mode menu I cannot select "Sequence", it is stuck on "Continuous". Any idea why?

@Fake0Name 4 года назад

"The Channel1FPGA recognize successfully!" "Channel1 2G PLL clock successfully!" ... Is that thing running beta firmware? The person who wrote the power on test messages either didn't care, or didn't speak english.

@shazam6274 4 года назад

Why would Tek release a new instrument with Beta firmware / GUI? It clearly has Missing functions, adjustments and waveforms.

@JWH3 4 года назад

There's some serious exclamation point abuse on that POST report!

@Kilohercas 4 года назад

I don't understand one thing. How to get 2GSps data bus from FPGA to DAC. As example most of FPGA clock tree performance is 100-600MHz, and regular IO could go up to 200MHz CMOS, ~600MHz LVDS, So how could they push that mush data through FPGA ? ( 2GBps at 16b is 32Gbps) Are they using transceivers ? But that would be too many for 2 dac's

@AllElectronicsGr 4 года назад

Using multiple channels in parallel 😅

@Kilohercas 4 года назад

@@AllElectronicsGr Does not work, since Samples per second, not data rate. Samples means you need to transfer 14b each cycles. So even at DDR, you need 1GHz clock with parallel port
