1.3 Erstaufladung
Before first use, fully charge the device. Charging time is approximately 1 hour using a 500mA minimum USB port or USB charger. A fully charged battery provides at least 2 hours of operation.
2. Bedienungsanleitung
2.1 Benutzeroberfläche und Anzeige
The device features a 320x240 pixel, 2.8-inch 16-bit RGB resistive touch screen. Navigation is primarily via touch control and a jog switch. The display shows scan points covering the frequency range.

2.2 Frequency Range and Input Modes
The Tiny SA Spectrum Analyzer operates with two inputs:
- MF/HF/VHF Input: 0.1MHz - 350MHz (High quality)
- UHF-Eingang: 240MHz - 960MHz (Lesser quality)
Switchable resolution bandpass filters are available for both ranges, between 2.6kHz and 640kHz. The fastest scanning speed is achieved with an RBW of 300kHz or wider, at approximately 2 scans per second. Scanning speed decreases with increased frequency span and decreased RBW.
2.3 Signalgeneratorfunktion
When not in spectrum analyzer mode, the device can function as a signal generator:
- MF/HF/VHF Sinus Output: 0.1 MHz – 350 MHz
- UHF Square Wave Output: 240 MHz – 960 MHz
It includes a built-in calibration signal generator for automatic self-test and low input calibration. An optional square wave output with a fundamental at -25dBm can be connected to the high input/output. Frequencies can be set to 1MHz, 2MHz, 4MHz, 10MHz, 15MHz, or 30MHz.

2.4 PC-Steuerung
The USB interface supports the Serial over USB (CDC) protocol, allowing for a range of commands to perform measurements or update internal settings. Drivers for Windows install automatically. Linux drivers are built into the kernel. Two software applications are available for PC control, both capable of capturing the device's screen.

2.5 Frequency Calibration
Frequency calibration ensures accurate measurements. This process involves measuring the internal reference frequency and applying a correction. The video below demonstrates how to perform frequency calibration using an external frequency counter.
Video 1: This video demonstrates the frequency calibration process for the Tiny SA Spectrum Analyzer. It shows how to connect an external frequency counter to measure the internal reference frequency, input the correction value into the device, and verify the corrected output frequency. The video highlights the importance of accurate frequency reference for precise measurements.
2.6 High Input Level Calibration
Calibrating the high input level is crucial for accurate power measurements. This procedure typically involves using a known signal source and adjusting the device's settings. The video below illustrates the steps for high input level calibration.
Video 2: This video guides users through the high input level calibration of the Tiny SA Spectrum Analyzer. It demonstrates connecting a signal generator with a known output level to the high input, adjusting the device's settings to match the known power, and verifying the calibration. The video also touches upon mirror suppression in the high input mode.
