Re: TinySA ULTRA LEVEL CAL -> Signal Level incorrect #ultra

 

What code did you use with the clear config?
Did the tinySA reboot after entering the code
Did the ref level indicator turn red after the clear config

Re: Calibration Issues on my new TinySA

 

Yes I can do that. What signal level are we looking for?
It will be later today before I can do it. About 6 pm CST local.
Thanks again Erik

No, I changed to RG223 cable and performed the test.

tinySA4_v1.3-556-g9825888.bin is CALIBLATION and SELF TEST OK

firmware after tinySA4_v1.3-563-g1da836e.bin is Signal Level incorrect.

The firmware after tinySA4_v1.4-33-ga8bffcf.bin is also Signal Level incorrect.

Yes

Calibration was performed using the RG223 cable.

This cable is also used in VNA and there are no broken wires.

Thank you in advance.

Can test again with a different coax cable?

Re: My tinySA Ultra Signal level Critical #ultra

 

As your description, the device worked properly before, it may be in use when the input is too high power or static electricity damage to the RF attenuator or RF switch.?It is recommended that you contact your supplier for repairs.

Re: Calibration Issues on my new TinySA

 

Do you have any means to check the level of the calibration signal coming from the HIGH connector?
A oscilloscope perhaps?

TinySA ULTRA LEVEL CAL -> Signal Level incorrect #ultra

 


zeenko store (aliexpress) Order date: Dec 18, 2022 I have tinysa ULTRA with HW V0.4.5.1.

Apply a new firmware today tinySA4_v1.4-33-ga8bffcf.bin to my TinuSa ULTRA
CONFIG -> MORE -> CLEAR CONFIG
CONFIG -> LEVEL CAL -> RESET CALIBLATION & CALIBLATE 100kHz to 5.34GHz

an error was displayed.
>1T 30.00026MHz -60,9dBm/T
Signal Level incorrect
Check cable between connection connectors
Touch screen to continue

I have reverted to the firmware around the date of purchase. Can I install the latest firmware?
tinySA4_v1.3-556-g9825888.bin is CALIBLATION and SELF TEST OK
tinySA4_v1.3-563-g1da836e.bin is Signal Level incorrect

Re: Calibration Issues on my new TinySA

 

Thanks for your assistance Eric,
I have used different ?Cables and have the same results.
Re: My tinySA Ultra Signal level Critical #ultra

 

This very looks very much like a broken cable or trace sowhere.
I suggest you contact you supplier and return the device.

I use tracking generator sweep from 0Hz to 1Ghz the result look like not linearity? Can you suggest my , possible? may be some part damage?.?

Hi Tom,

I created a PDF and uploaded it together with the ODT to the files section, you can replace it (with the same name) for the next revision.

I did three small changes as described below:

1. The Revision TimeStamp is out of sync:



Revision TimeStamp: 202212271050


2. Outmask is no command but belongs to the line above ("hop" is Ultra only). Do you also want to document the Ultra command set, there are some more?

3. In version?this text looks strange, maybe a copy/paste from somewhere.

Thanks very much for this method Peer, immediately brought back memories from my first job, we used to have two " wobbulators "
to align central antenna amplifiers and umsetzer's ( frequency converters from uhf to vhf tv channels ) in a large system.
They would check and re-align as necessary these components with the wobbulator.
Did work with them on occasion but did not understand exactly how they worked, looked like magic then, guess i learnt some in the mean time.....
Will try this out soon, all the best and thanks for the diagrams too, makes sense now, inject sweep signal on the input of the device whilst
detecting the output signal with a diode/capacitor test probe or better, great.

Re: My tinySA Ultra Signal level Critical #ultra

 

I see you have another spectrum analyzer.
Please enable the CAL output (MODE/CALIBRATION OUTPUT/30MHz) and measure the output level of the call output with your other SA

Re: Calibration Issues on my new TinySA

 

Your unit is genuine.
Could you first do the calibration and then the selftest using a different coax cable to see if this improves the results?

Re: Calibration Issues on my new TinySA

 

Thanks for the quick response,
In my troubleshooting of the issues i did upgrade the firmware to the latest version without problems.

Here are the results for test 7
