First Use

The tinySA comes in a sturdy box for protection during transport

Inside the box you find the tinySA with some accessories

  • two SMA cables and a barrel connector
  • an antenna with an SMA connector
  • a USB-C cable

After unpacking the tinySA insert the USB cable into the tinySA and connect the cable to a USB charger or computer USB port to charge the tinySA. One hour charging should be sufficient for first usage.

After charging the USB cable can remain connected or can be disconnected.

The next steps are also explained in the video on first use

Kurt Poulsen wrote a document on the tinySA that can be found through

Execute these steps:

  1. Use one of the supplied SMA cables to connect the low port to the high port.
  2. Power the tinySA using the tiny power switch at the top.
  3. Touch the screen to activate the menu system and select CONFIG and then SELF TEST. If navigation goes wrong use the BACK button or switch the tinySA Off and On to get back into a known state. If all goes well the self test will pass all tests and you can touch the screen once more to conclude.
  4. Leave the high and low port connected for the next step
  5. Next step is to do the power calibration of the LOW INPUT MODE. THis has to be done only once for one frequency and it does not have to be repeated before every measurement as the level calibration is very stable and frequency independent. From the CONFIG menu execute LEVEL CAL. The red level indicators at the top and bottom should turn white to indicate the calibration has succeeded.

Optional step:

  1. Doing the level calibration for the high input mode is a bit more complex but clearly explained in this video

Now the tinySA is ready to do measurements.

Connect some input signal to the low input and go back to the INPUT menu, you can select which input to use from the MODE menu, select either LOW INPUT or HIGH INPUT.

WARNING!!!. The input signal must be below +10dBm otherwise the tinySA can be damaged. Use an external attenuator when trying to measure signals with higher power levels.
WARNING!!!. Both inputs can tolerate maximum 10 Volt DC. Higher voltages may damage the inputs. Use an external DC block when measuring signals with higher DC components.
WARNING!!!. Using the supplied antenna makes the tinySA very susceptible to ESD damage or overloading. Only use the antenna with great caution. Never put the antenna close to a transmitting antenna. Never touch anything with the antenna
WARNING!!!. You can destroy the low input attenuator when you enable a high power high output signal and the high and low ports are still connected after doing a selftest or level calibration. Afways disconnect high and low inputs before enabling the high output

Use the FREQ menu to set the frequency range displayed and the LEVEL menu to set the displayed levels.

You can always go back to a defined state by clicking the PRESET button in the input menu and then LOAD STARTUP
