Hello,

I was reading through the documentation and was curious about the external modulation function. Does this allow one to input through the high input either modulated audio or a modulated tone that is of a different frequency from the built in 800hz tone?

Thank you,

- Mike

I haven't spent enough time in tinySA.exe lately with the various changes in the tinySA itself.

How about: ? U = ?bandwidth ( in MHz). / ?weight ( in kilos )

Erik,
? ?The level/dB setting was set to a default value of '2' which is why no sweep data was displayed. Once I changed it to '32' the sweep data displayed properly.? The sweep data was displayed 3dB too low because of the Zero level(dB) setting of -125, this needs to be -128.? Are those to values initialized in the tinySA.cfg file included in the?? directory?? The cfg file in that directory is over a month old.

level/dB changed from '2' to '32', Zero Level(dB) should be -128? ? ? ? ? ? ? ? ? ? ? ? ? ? ?After level/dB changed from '2' to '32' sweep data is visible.
? ???


After the above changes, the Mockup device is still the only device shown in the SerialPortSelector but all else is working correctly.? This is probably only a issue if more than one tinySA is connected, or a tinySA and a NanoVNA are connected since they use the same VID:PID. Note: I just connected a NanoVNA to another port on my computer and, after File->Connect only displayed the Mockup device. Returning to the Spectrum screen locked up the application when a sweep was attempted.

If you do not see the serial port, unplug the device from USB and wait a second and connect again.

Erik,
? I tried unplugging the port and cycling power on the tinySA.? The Mockup device is still the only selection that shows up in the Connect dropdown list.? The primary problem is that even though the tinySA serial port is not showing up in the tinySA.exe dropdown list it is successfully receiving commands from the application. The tinySA.exe screen is not plotting whatever data is being received back and it is not properly registering the tinySA serial port in the drop down list.

?I also noticed that 'Zero Level (dB)' value under the settings tab is still defaulting to -125.

Erik,

2. Strangely, even though the main interface won't run and no serial port shows as selected, the screenshot function works.

By chance I tried to capture a screenshot and it worked, even though the main screen shows no device connected.



3.? I tried deleting the 'Kaashoek\SpectrumAnalyzer' directory and letting tinySA create a fresh installation without any change.

- Herb

Further investigation, after seeing that the screenshot tab works, shows that pause and resume commands are being sent to the tinySA when a single trigger is performed although no sweep data appears on the tinySA.exe screen.? Again, only the Mockup device is displayed when File->Connect is selected.

HP141T

Mmm. HP141T has resolution filters down to 10Hz and goes up to 1250MHz.
Don't know how to use this in a weight normalized comparison

Tried again with a VISA debit card and the transaction did go thru. ?

Looking forward to using tinySA — maybe I can remove my 70 pound HP141T and HP8443 tracking generator from the bench ...

Erik has included features in the tinySA that even more expensive spectrum analyzers sometimes fail to include.? One of those features is an ample choice of display units.

The following logarithmic display units are provided:

Default dBm units.? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?Optional dBmV units? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?Optional dBuV units
? ??? ??

The following linear display units are provided:

Optional Volts units? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? Optional Watts units
? ??


? ?Most users will be happy with just the default dBm units but there are disciplines where the other display units are the standard.? The conversions from dBm are easy but having the tinySA do them eliminates errors and allows screen captures to show the correct units.

? ?It took Erik some time to get the automatic scaling to work seamlessly between all the different units, and is a example of his goal of providing features in the tinySA not seen in other devices in its price class.

New FW released: v1.0-39
New tinySA.exe release

Changes:
- Small change to increase the robustness of tinySA.exe during screen capturing.
- Better status display of trigger status (ARMED/PAUSED)
- Corrected a help text typo (IN to OUT -> HIGH to LOW)

Hi Herb,

I think delivery reliability also plays a part. It could still be at -H4 in January.

Gyula,

I added a new example to the wiki to demonstrate the use of triggering to capture ISM transmissions

Nope. if it continues at this rate there should be sufficient for some more days

Please update. ?Thank you.
