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

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

True that. If I had my way it would be a world-wide law that every battery powered portable device has to have a hard OFF switch. However there is also the protection board attached to the cells that

The TinySA model has a physical switch that disconnects the battery from the power circuit. The iPod and newer devices are built on a digital switch that constantly draws some current.

While the long shelf life is true, it is also true that in the real world there is often a very small but non-zero current drain on the cells. Sometimes I wonder how many long forgotten iPods have

The internal reference should be stable enough for the resolution of the tinySA Should be well within one 1 Hz stability. -- Designer of the tinySA For more info go to https://tinysa.org/wiki

Thank you for the information.? When setting the tinySA aside, one does not consider such a thing.? ?I will now. 73s,

Hi. Erik - Has it been tested at what environmental temperatures the parameters of the pilot signals measured will start to shift? (For example, if you put the tinySA ULTRA in a closed device box and

No formally specified minimum or maximum operating temperature What temperature are you thinking about? -- Designer of the tinySA For more info go to https://tinysa.org/wiki

*If you just want to measure the loss at a few frequencies, then you could measure the output of an oscillator direct then connect the SA and re-measure. Don't overload the input. Not as good as a VNA

Is there any specified operating temperature range for the TinySA ultra device?? ?I cannot seem to find this on the wiki or searching group messages. Cheers, TC

Hi. Yes, it caught my eye right away. I enlarged the picture I took earlier.

Hi. Erik, thanks for the reply. For a few hours tinySA ULTRA was turned off and when I restarted it, this information appeared on the screen (Pictures attached to the letter). The only way to get

*if you have a look to the copper pattern of the ribbon cable you can see that it is not centered - you can also see that the size of the isolation area at the edges is different -? and also on the

Lithium Ion batteries have almost zero self discharge. So providing there is no current draw they should remain charged anlmost indefinitely. Having said that, it’s kinder to the battery to not

Hooray for the tinyVA battery.? I had not used my unit in over a year, turned it on, and the battery was at almost full charge.? To me, that is an outstanding shelf life from a quality rechargeable

Hi Dave, Lots of useful info there. Thanks. I will also write separately to you. -- Julian
