Re: Reference level and input attenuator value management #features
Hi Erik My humble opinion is leave it as is. It is working very well with the AGC functions and serves the first time user best possible as he hardly need to know what he is doing ? I have both

Re: TInySA always initializes 0 ... 350Mhz
Yep. There is a bug in loading the startup configuration

TInySA always initializes 0 ... 350Mhz
I saved a different setup in [store as startup]. When Tiny boots, for a moment we have the setup, then it defaults. You need [load startup] to recall the setup. Is this right? I tried to record it on

Re: "Help" Console Command #console_commands
Thanks for the answer. I'm looking at the commands. I like to leave the settings saved in a txt file. When using "clearconfig", I restore the settings. Thank you again!! 73

Re: "Help" Console Command #console_commands
Igor, Erik intended to include those commands in the final release but there was a deadline to get the tinySA into production, and so, those commands never made it.? The only way they can be

Re: Reference level and input attenuator value management #features
Yep. On a $1000.00 plus instrument it would be negligent if you didn't have that type of automatic protection built in.? I guess the same thing on the tinySA would reduce the number of "my tinySA is

Re: "Help" Console Command #console_commands
Erik, I am testing the commands and have not resulted in the commands below: *trace {store | clear | subtract}* For these commands everything works fine: *trace {dBm | dBmV | dBuV | V | W}* *trace

Re: TinySA-Saver
Gary I have not done ANY testing on tinySA-saver. It is just a crude, incomplete hack to enable nanoVNA-saver to sweep with tinySA. Unfortunately tinySA-saver is low on my priority list, mostly

Re: Reference level and input attenuator value management #features
I found a good reason to have coupling if ref level is set to 20dB or higher The noise floor with the widest RBW is, with a ref level of 20dB just visible if attenuation is set to 10 dB So if a user

TinySA-Saver
Seems whatever I try to do results in a "complex division by zero" error. Setting marker, clicking on trace... I am running it from the Anaconda prompt, and I get first error right after starting

Re: Reference level and input attenuator value management #features
For any attenuation applied the displayed level always reflects the level at the input , regardless of the applied attenuation

Re: Reference level and input attenuator value management #features
My 2 cents: if manual attenuation is selected the IF gain should compensate so the reference level stays the same. Gary W9TD

Re: Reference level and input attenuator value management #features
For a first time user, would it be better to have coupled (e.g starting attenuation level) equal to refelevel if reflevel >= 0? Or should it be better to go to coupled mode if the reflevel is manually

Re: Reference level and input attenuator value management #features
Older analyzers such as those in the HP141 mainframe had uncoupled rf attenuation and IF gain since they were in separate plugins. The display reference level did read correctly whatever combination
