content: Using the python script I have successfully extended the bandwidth of my scope and function generator:SDS2202X-E >> SDS2352X-ESDG2042X >> SDG2122XI want to do Bode plots so I tried to enable the AWG option in the scope via telnet using 'LCISL optioncode,hexkey' but AWG doesn't show up under Bode Plot II>Config>Source.Next I went to Utility>Options>Install and tried entering the key from the script to install AWG but it said the key was invalid.The scope says I have a temporary licence with 30 uses but then "Failed to connect to AWG".Any ideas please?Mike

content: Quote from: 2N3055 on June 25, 2025, 12:49:28 pmOh, I thought after upgrading the scope bandwidth I had to enable the AWG option.Anyway the main problem is that AWG does not appear in the Source list when connected to the function generator. Only USB and LAN appear.Mike

content: Quote from: 2N3055 on June 25, 2025, 01:59:54 pmWell that is interesting. With my previous AWG (SDG1062X) the option AWG appeared in the Source menu with LAN and USB.With the SDG2042X there is no AWG option but you are right, it will connect via the LAN and the Bode plot works so thank you for that.Just two remaining issues for me to resolve:Why doesn't it connect via USB (I've tried several cables)?Why do I only have a temporary AWG licence with 30 uses remaining?Also, do you know if it's possible to dump the memory from the SDS2202X-E scope? It would be useful to see what the AWG licence key is.Mike

SAG1021I has no user interface so it is controlled through the scope. That is not used with SDG2000X.Also it makes me think you don't have latest FW for your scope:2024/06/25 1.1.20R7 1. Standard software functions of FG and LA.If USB does not work, you might be connecting cable the wrong way. Are you connecting scope into SDG2000X or you are connecting SDG2000x into scope?

content: Quote from: 2N3055 on June 25, 2025, 03:32:19 pmGreat, thanks for explaining that. The USB cable was connected A to the scope and B to the AWG.I have just updated the scope to 20R7 (from 20R3) and now when I do a LAN connection test it says "Unidentified AWG!" ...I then tried downgrading the AWG from 2122 back to 2042 using the original licence key but nothing happened.I feel like I'm going down a rabbit hole ...Mike

content: You don't need to downgrade anything. Those options have nothing to do with how the devices work in this regard.Make sure everything has the latest firmware, do a factory reset twice, click your heels thrice, and try again.

content: Quote from: KungFuJosh on June 25, 2025, 04:52:49 pmThank you. You can tell I'm new at this and I appreciate all the advice.The AWG does work with firmware R7 after all. It was my mistake, after installing it I forgot to set the AWG's IP address in the scopeI've given up on USB. The LAN connection works, and while not as convenient it will have to do.The final mystery then is why I could downgrade the scope from 350MHz to its original 200MHz by sending MCBD and the original licence key, but when I try that with the AWG the licence key and product type don't change.I thought the upgrade process was reversible?Mike

content: Quote from: Mike99 on June 25, 2025, 06:33:26 pmIt certainly should be as the BW licence only changes the BW but it is easy to get SCPI syntax wrong.Always record/save the base/original BW license code before attempting upgrades.Bode plot has always been plug and play via USB with the scope the master and the AWG the slave so USB-B must connect to the AWG.Try another A to B USB cable, you should have one for each Siglent instrument you have.

content: I have many USB A/B cables and tried several with no luck. The AWG is brand new so unlikely to be at fault. My previous AWG (SDG1062X) had no trouble communicating via USB until the accident (described elsewhere) when the earth lead on my scope probe touched a 2kV supply, so maybe the scope's USB port suffered some subtle damage (it still reads and writes USB memory though).I make notes as I go along and have a record of my AWG's original 40MHz licence key. I'm using telnet from a Windows cmd window and pretty certain I have the correct syntax. It works for the scope but not the AWG.Mike

content: After persevering some more I did get the AWG to accept the original licence key by using putty instead of telnet. Maybe I did get the syntax wrong earlier.Anyway I'm happy with that so now the only remaining issue is that the scope doesn't recognise the AWG via USB.KungFuJosh mentioned a factory reset for the scope - is that the default button or something more involved?Mike

content: Quote from: KungFuJosh on June 26, 2025, 04:25:17 pmThank you. Now, after upgrading the firmware to latest and doing a factory reset the Options button (which previously displayed temporary licences for AWG, MISO and WiFi) has disappeared from the Utility menu. I guess that confirms the advice I was given here earlier.EDIT: Even better, the AWG now talks to the scope via USBThank you all so much for your patient advice.Mike
