Siglent SDS1052DL+/SDS1102CML+ hack
« on: September 24, 2019, 03:09:20 am »
Hello,I have been searching around, but didn't find any info about Siglent SDS1052DL+ or SDS1102CML+ hack. Is there anyone know about this? Thank you very much!

The DL+ is only available in a 50 MHz model these days so I don't know if the internal SW supports higher bandwidth.
However the CML+ models do as they come in 50, 100 or 150 MHz models.

Sometime back I installed a later firmware onto a new SDS1102CML+ and for some reason it flashed it to SDS1152CML+ and my customer got a nice surprise !  ;D

SDS1000DL+/CML+ domestic markets sisters (A)

带宽   50 MHz 、70 MHz 、100 MHz、150 MHz
实时采样率   
SDS1052A:500 MSa/s   <<===  This 1052 is exception in this serie with 500MSa/s max ADC system *)
SDS1072A:1 GSa/s
SDS1102A:1 GSa/s
SDS1152A:1 GSa/s
通道数   2 + EXT
存储深度   
SDS1052A:32 Kpts
SDS1072A:2 Mpts
SDS1102A:2 Mpts
SDS1152A:2 Mpts

*) and because this, imho, it is difficult to think possible SW change for 1GSa/s models (different HW)
But what I have seen 52DL+  analog front end BW is really far over 50MHz. (perhaps front end like 1072A but different memory and ADC system)
72A, 102A, 152A have same 40k short and 2M long memory and max 1GSa/s
52A (as also 52DL+ outside of china) have 32k short memory alone and max 500MSa/s
Also inside these series systems there are not finnish guy Linus Thorwalds secretions and emissions.

Only what I remember that I have seen somewhere in this forum is that someone have added 2M memory to SDS1000CNL  so that is works like SDS1000CML after mod.
(and CNL or CNL+  are 1GSa/s and are not same as DL or DL+ what have 500MSa/s)
Previously there have been 25 - 200MHz models in DL series (pdf) so hardware mod for rise analog front end bandwidth is perhaps possible because I think analog front end have not changed so much.

If practice and theory is not equal it tells that used application of theory  is wrong or the theory itself is wrong.
It is much easier to think an apple fall to the ground than to think that the earth and the apple will begin to move toward each other and collide.

Thank you Tautech and rf-loop.  This confirms my assumption, so me and my friend did some work.  The result is  pleasing.
This is verified on SDS1102CML+ with FW version  6.01.01.21R2 and SDS1052DL+ with FW version 6.02.01.10R2.
The trick is the same.
1) Input below command in a Notepad file and rename the file as startup.sh
 #! /bin/sh
telnetd
And then put the startup.sh file in a USB disk root directory, and insert the USB disk to scope. The telnet will be  available.
2) Connect scope to local network via LAN, set IP by DHCP.
3) Open cmd window on PC, input command  ' telnet xx.xx.xx.xxx  '(means IP address of the scope)
4) Enter the user name 'root', enter the password 'ding123'
5) mount -o remount,rw,sync /usr/bin/siglent/firmdata0
6) rm /usr/bin/siglent/firmdata0/bandwidth.txt
7) Restart oscilloscope

Now go to System Status page, the model name is changed. Tested with a generator, the bandwidth is indeed  upgraded.

@miyagi, could you show me the output of this SCPI command on both scopes (CML+ and DL+)?

MD5_PR?
