+1. (Recommended) Attach a 20 dB attenuator (any that support the frequency range) to the TinySA Ultra "RF" port.
+2. Connect the TinySA Ultra's "RF" port (with attenuator) to the Mirny channel 0 output SMA port.
+3. Turn on the TinySA Ultra and set it to "Spectrum Analyzer" mode. 
+4. Set the frequency range to cover the expected output (e.g., 800 MHz to 2 GHz).
+5. If the marker is not on the peak, click "Marker"->"Search Marker"->"Peak Search" to find the peak signal.
+6. Repeat 2-5 for other channels

 1. Install gqrx `nix-shell -p gqrx`
 2. Connect HackRF One via USB cable only
 3. Run gqrx and choose `HackRF HackRF One...`

+
+After running `artiq_sinara_tester` with Almazny installed, use TinySA Ultra to check the frequencies, similar to the [Without Almazny](#Without-Almazny) section:
+
+1. (Recommended) Attach a 20 dB attenuator ([BW-S20W5+](https://www.minicircuits.com/WebStore/dashboard.html?model=BW-S20W5%2B)) to the TinySA Ultra "RF" port.
+2. Connect the TinySA Ultra's "RF" port (with attenuator) to the Almazny channel 0 output SMA port.
+3. Turn on the TinySA Ultra and set it to "Spectrum Analyzer" mode. 
+4. Set the frequency range to cover the expected output (e.g., 6.8 GHz to 7.5 GHz).
+5. If the marker is not on the peak, click "Marker"->"Search Marker"->"Peak Search" to find the peak signal.
+6. Repeat 2-5 for other channels
+
+Expected output: The output amplitude will sweep due to attenuator testing, but the frequencies should remain stable.

 ### With Almazny (ARTIQ 7)
 
 At first, `artiq_sinara_tester` will prompt you for testing Mirnies as the would be without Almazny.
