| A review of the GWInstek 1054B |
| (1/16) > >> |
| saturation:
There are few technical reviews of the 1054B available on the Internet or the forum, so this thread will supplement missing elements and avoid repeating what others have already mentioned. For an executive summary, see only the bold items. A key feature of this model as well as variants in the GWInstek lineup is the use of a Zynq SoC allows for faster data acquisition and processing at an entry level price range, $429 as listed. However street prices vary and my unit was new < $330. I received a firmware 1.09 1054B early May 2016 and confirmed nearly all items in its spec sheet as accurate as published by GWInstek. I found one bug, a typo in the help file. Much of the GWInstek sales literature, videos and specifications target the market of the Rigol 1054Z. It has been discussed elsewhere on the forum. I compared the spec sheets for the 1000B and 2000E series against the 1054Z, see attached. Users can then differentiate both series together, assuming all data in the spec sheet of all models are accurate. I used marmad's method for estimating wfms/s rates without using a trigger output port, and it returned at least 30,000 [ spec'd at 50,000 wfms/s] at its optimal setting for speed. https://www.eevblog.com/forum/testgear/a-simple-technique-to-measure-waveform-update-rates-on-dsos-with-no-trigger-out/ I installed the latest firmware to date, 1.14, 3 weeks ago. The firmware update instructions are vague and on first try it did not load correctly, but it did not brick the scope. On second try, I used "safe mode" and it installed problem free. I installed all available "apps" without issue, by simply opening the file on USB. USB can be hot swapped anytime without locking the DSO. There is no changelog from GWInstek. Further testing did not reveal new bugs. There are 2 marked changes compared to 1.09 not described elsewhere on the Internet, as of this post. There is a noticeable increase in overall speed compared to 1.09, but not quantifiable. * A trigger out in now available from the probe compensation port, just turn the adjust knob until option appears * The wfms/s rate has been increased to ~ 120,000 wfms/s [ actually measured] from its specified 50,000 wfms/s, at optimal settings A key feature of this DSO is most all processing can be done in real time or after acquisition, on the buffer. The DSO can thus be configured with all processing turned off, adjusted for fastest wfms/s, a rough trigger set, data captured and analyzed in stop mode: filters, FFT, measurements etc., once the glitch is characterized, the trigger can be optimized for glitch capture, higher memory depth selected, and thus slower wfms/s, for better waveform fidelity. This model was released in middle 2015. A mostly detailed hardware review was done by Dave on the 100MHz version on Nov 2015 in the forum. Model variants were reviewed by others and linked below, including detailed teardowns. https://www.eevblog.com/forum/blog/eevblog-824-gw-instek-gds-1000b-oscilloscope-teardown/msg809286/#msg809286 https://www.eevblog.com/forum/testgear/gw-instek-gds2204e-(200mhz-4-channel-dso)-review/ https://www.eevblog.com/forum/testgear/gw-instek-gds-2000e-teardown-short-review-comparison-with-rigol-ds2000(a)/25/ https://www.eevblog.com/forum/testgear/new-gw-instek-2000-series-digiscope-gds-2202e/ https://www.eevblog.com/forum/testgear/gw-instek-gds-2000e-released/ More, photos, added comments etc., to follow as time permits. |

Saturation, thank you for your review and comparison :-+ |

I'm finding the PDFs difficult to read. Better put everything in a posting! |

Thanks. The color? I have a B&W version with symbols replacing color. If its still unreadable let me know; all pdf files I posted are open with security removed so you can change my notes as you please. nctnico, with your good review I'm sure you know most of these already, it helped make my decision to get a 1054B. @SkyMaster your welcome. --- Quote from: nctnico on June 18, 2016, 09:18:39 am ---I'm finding the PDFs difficult to read.

New firmware released V1.15 dated 8 31 2016 no change log from Instek. Have not yet run it through it paces. The firmware release has not been announced nor appears on the English website. To find it you need to register as a "VIP" then go to the product of interest. You can register with a bogus email address, they do not confirm the email address to enter the VIP area. Problem free install from 1.14. Ran tests for about 2 hours. Its appears mostly performance enhancements. Increase FFT speed Increase system speed More contrast in intensity grading |
