5. Einrichtung

Before operating your TinySA, ensure it is properly set up.

5.1. Erstes Einschalten und Selbsttest

Connect the CAL and RF ports using one of the provided RF cables.
Turn on the device using the Power On/Off switch.
On the touchscreen, navigate to KONFIGund wählen Sie dann SELBSTTEST.
The device will run a series of internal tests. Ensure all tests pass. If any test fails, refer to the Troubleshooting section.

5.2. Pegelkalibrierung

For accurate measurements, perform a level calibration.

Ensure the CAL and RF ports are connected with an RF cable.
Navigieren Sie zu KONFIGund wählen Sie dann LEVEL CAL.
Choose the appropriate calibration range (e.g., Kalibrierung von 100 kHz bis 5.34 GHz).
Befolgen Sie die Anweisungen auf dem Bildschirm, um den Kalibrierungsvorgang abzuschließen.

6. Bedienungsanleitung

The TinySA operates in two primary modes: Spectrum Analyzer and Signal Generator.

6.1. Spectrum Analyzer Mode

This mode allows you to visualize the frequency spectrum of RF signals.

Accessing Mode: From the main screen, tap the screen to bring up the menu. Select MODUS, Dann Spectrum Analyzer.
Einstellbereich der Frequenz: Wählen FREQUENZ from the menu. You can set START, STOPPEN, STADTZENTRUM, Und SPANNE frequencies using the on-screen keypad.
Verwendung von Markern: Wählen MARKER from the menu. You can add multiple markers (e.g., 2, 4, 6, 8 markers) to identify specific peaks and their frequencies/strengths.
Pausing and Saving: To freeze the current display, select PAUSE from the menu. To save the screen capture, go to LAGERUNG und wählen Sie SAVE CAPTURE. You can name the file mithilfe der Bildschirmtastatur.
Ultra-Modus: To extend the frequency range up to 6GHz, navigate to KONFIG > MEHR > ENABLE ULTRA. You will need to enter an unlock code (4321).

6.2. Signalgeneratormodus

This mode allows you to generate various RF signals for testing.

Accessing Mode: From the main screen, tap the screen to bring up the menu. Select MODUS, Dann Signalgenerator.
Einstellfrequenz: Tippen Sie auf FREQ and enter the desired frequency using the on-screen keypad.
Einstellungsniveau: Tippen Sie auf EBENE and enter the desired output power in dBm.
Modulation: Wählen MOD to choose between AM, FM, or None. You can adjust modulation frequency, AM depth, or FM deviation.
Ausgabetyp: Wählen AUSGABE to choose between Sine or Square wave.
Fegen: You can enable a frequency sweep by selecting START SWEEP and configuring the sweep parameters.
