A review of the GWInstek 1054B

<< < (9/16) > >>

saturation:
By chance I found out new firmware released this week.  Other DSO in the Zynq line could check if they too have new firmware for their models.  Have not yet time to test: V 1.18

In packet:
No changelog
No update instructions

bitseeker:
Saturation, it's great that you've been able to maintain this thread. As you said, you're probably the only one able to provide so much ongoing info on the 1054B. :-+

saturation:
Currently change log and firmware:


Version 1.08

1.Fixed the system crash randomly which caused by the ¡§Advance Math¡¨ function
2. Fixed the displaying issue of XY mode under certain circumstances
3. Fixed the time base error when the ¡§AUTOSET¡¨key pressed under ¡§Window Zoom¡¨ mode
4. Fixed the AD malfunction under certain circumstances

Version 1.09
1.Added German & French icons and help menu
2.Adjusted the maximum value of the waveform brightness


Version 1.11
1.Added Korean icons and help menu
2.Added Russian icons
3.Fixed the residue waveform issue
4.Fixed the system freeze bug after the QR code menu activated
5.Added the DVR calibration under distributor mode

Version 1.12
1.Added Russian help menu
2.Fixed the initial value for the ¡§Advance Math default¡¨ expression
3.The output polarity of the Go/No-Go has been adjusted which same as the GDS-2000A series

Version 1.13
1.Fixed the Trigger Filter bug.

Version 1.14
1.Changed the display method for waveform interpolation.
2.Fixed the pictbridge's connectivity issues.
3.The Trigger out function is activated now. (Press UTILITY -> Probe Comp. -> Frequency)

Version 1.15
1.Add Multilanguage: Spanish

Version 1.16.001
1.Fixed the trigger level offset issue, if the vertical position was shifted out off the screen range.
2.Fixed the ¡§Advance math¡¨ algorithm which caused the system crash.

Version 1.17.001
1.Added USBDelay command in order to solve the USB data leaks for WIN10.
2.Fixed the ext trigger of roll mode which may cause the system crash.
3.Fixed the zoom state malfunction for horizontal position command.
4.Changed the value range of trigger hold off command: the minimum value changed to 4ns from 10ns.

Version 1.18.001
1.Removed the extra unwanted carriage returns symbol for *LRN? command.
2.Fixed the starting condition of autotrigger for Datalog function (APP funciton)
3.Extended the "Duration" until the 999 hours for Datalog function (APP funciton)

Version 1.19.001
1.Fixed the Japanese translations error for digital filter menu tree. (APP function)
2.Updated the simplified Chinese menu tree
3.Updated the License encoding rule


Note, the changelog is not entirely complete.  After 1.14 when the trigger out was activated it also increased the wfms/sec rate which is not mentioned officially except by my testing on this thread.


I have not found any functional change in 1.18 since I last posted.

maxwell3e10:
I just got a new GDS-1054B, primarily motivated by deep memory per channel and the hope for a smoother user interface.
It seems there are missing bits in the 8-bit acquisition. Here is a screen shot of a transient from the probe calibration signal. I stop the acquisition and then increase vertical scale 2 steps. The display is set to dots. The small step between levels is consistent with 256 bits over 10 vertical divisions. But some steps are twice as large. It seems to happen on various time scales and sensitivity scales. I also checked the same problem exists if I save data to file, so its not a display problem. I don't think there should be missing codes in 8 bit ADC.

Hope it serves you well.  I agree with your insights of the screen capture but I cannot reproduce what you show, and I am not clear as to what this pulse represents.  Is this the scopes onboard cal out?   If so, its 2Vpp.  To get a 1mV/div read you have the scope scale at x1 with a probe set at x10? You are also looking at the very edge of a waveform given the trigger location, captured the waveform to memory then zoomed. 

Just quick thoughts:

Since you have a pattern in that waveform that is fairly consistent, it can be the slower ~1000 wfms/sec rate at 50us so  gaps could also be 'dead time'  even if sampling is 1GSa/s; not necessarily an ADC issue.

A dot mode image is purely a series of dots, we see lines.  This means the settings are distorting the data or its artifacts; stretching out what should be a dot.  Likewise the gaps seen by the vertical amp setting cannot be said to be free of artifacts either.

Since I can't reproduce your image to see it on my DSO, I can be wrong, but it hard to make clear inferences based on the settings shown.
