Re: ZS-405-Updates

 

I agree with what has been said, done numerous updates no probs. Always do a self test prior to an upgrade, else if you have damaged the unit, you may think it was due to the upgrade

Hi.

If you connect the tinySA Ultra computer to the tinySA APP program, you will see this information in the log window.

Re: QUESTION on VERSION

 

Update your firmware then look at the version info. It was part of firmware update a while ago.
Re: QUESTION on VERSION

 

The older models do not have the model on the front of the case.
For older models, before they started using the Z S series as designation of model, the lable on the back of the TyniSA will tell you.
Mine is marked " TyniSA ultra" so it is the ZS405.
If you have the plus, it will be on the lable. Then you compare your back lable with the WiKi as shown.
It's that simple.

My question was where do I determine which model I have?? I know they are different.

Re: TinySA Ultra operating temperature

 

I plan to leave this unit outside, 0 to +40 deg C.? it may have to go inside an enclosure which would bring the high temperature up to 70 deg C.? It sounds that these limits are untested?

QUESTION on VERSION

 

Dumb question, but:

Where do I find the ZS-405, 406, or 407 in/on my TinySA/Ultra.? It's not under "Version".

Re: U22 AS179-92LF replacement

 

I will document my attempt but it wont be for a few weeks as I’ve got other stuff to do first.?
I will report back regardless of the outcome, but wish me luck.

Hi :)

If possible, take some pictures of the U22 chip replacement and a few lines of text, was it an easy replacement, etc...

Re: ZS-405-Updates

 

Yes, if you want an up to date insterment, with any bugs fixed and any new features.
If not, and you don't need any new features and it works for all the measurements you need, then no.
?
Your probably going to get answers saying, if it isn't broke do not fix it. Which is the cavemans answer. Those who still rub sticks together instead of using matches.??
Updating firmware is not fixing it, it is improving it.
You have to make up your own mind.
Myself, I keep ALL my equipment up to date.
I find it more useful that way.
Have fun?
May you be safe and healthy

Re: U22 AS179-92LF replacement

 

Thanks.? I ask the question as it says "20 Mhz to 3 Ghz " on the data sheet, and most of my work is in the HF bands ( 1.8 Mhz to 30 Mhz ) and the TinySA Ultra itself says " 100Khz to 6Ghz "? I just wanted to make sure this is the right component.
Thanks again.
Dave.

U22 AS179-92LF replacement

 

Hi, my TinySA Ultra is showing all the symptoms of a failed U22. Self inflicted I think so can’t blame the unit.
I’ve ordered a new unit as the supplier I bought it from has offered me a discount.
So as I’ll have nothing to loose I thought I’d have a go at replacing it. I’ve got a hot air soldering unit so lets see.
My question is the description on my preferred suppliers ( CPC ) for a AS179-92LF is “? Switch IC, SPDT, 20MHz to 3GHz, 2V to 5V, SC-70-6?-? AS179-92LF “?
Could someone please confirm this is what I require.
Many thanks and apologies for the capitals it’s a result of copy/paste.
Dave
