Portable TinySA Spectrum Analyzer, Handheld Tiny Frequency Analyzer 100kHz to 960MHz MF/HF/VHF UHF Input, Signal Generator with 2.8 inch Touch Screen Battery Spectrum Analyzer with two inputs, high-quality MF/HF/VHF input for 0.1MHZ-350MHz, lesser quality UHF input for 240MHz-960MHz Built-in calibration signal generator that is used for automatic self-test and low input calibration. Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz.Color display showing 290 scan points covering up to the full low or high-frequency range. When not used as Spectrum Analyzer it can be used as Signal Generator, MF/HF/VHF sinus output between 0.1MHZ-350MHz, UHF square wave output between 240MHz-960MHz. Connected to a PC via USB it becomes a PC-controlled Spectrum Analyzer.Built-in rechargeable battery allowing a minimum of at least 2 hours portable use Product Description The tinySA is a small spectrum analyzer, primarily intended for 0.1MHz to 350MHz Specification: * Display resolution 320*240 pixels * Screen diagonal 2.8″ * 16 bits per RGB pixels * Resistive touch control * Jog switch control * USB serial port control * Optional TTL USART port (SW not yet implemented) on the internal PCB * Linear power supply to avoid switching noise. Spectrum Analyzer with two inputs, high-quality MF/HF/VHF input for 0.1MHZ-350MHz, lesser quality UHF input for 240MHz-960MHz. Switchable resolution bandpass filters for both ranges between 2.6kHz and 640kHz Color display showing 290 scan points covering up to the full low or high-frequency range. Input Step attenuator from 0dB to 31dB for the MF/HF/VHF input. When not used as Spectrum Analyzer it can be used as Signal Generator, MF/HF/VHF sinus output between 0.1MHZ-350MHz, UHF square wave output between 240MHz-960MHz. USB Charging Charging time max 1 hour on 500mA minimum USB port or USB charger. Operation on fully charged battery for at least 2 hours PC Control The USB interface implements the Serial over USB (CDC) protocol and there is a large set of commands that can be invoked over the serial interface. These commands can be used to perform measurements or update internal settings. The driver for Windows will install automatically after connecting to a Windows PC. The driver for Linux is built into the kernel Compare with more expensive spectrum analyzers, the tinysa of more cost-effective there are some limitations 1) The internal phase noise sets a clear lower limit for phase noise measurements 2)The minimum resolution bandwidth of 2. 4kHz makes it impossible to see more spectral detail 3)The high input (240MHZ to 960MHZ) has very limited image suppression and only one level optional built-in attenuator which makes it difficult to interpret complex signals 4)The high input optional input attenuator is frequency-dependent and varies between 25db and 40db 5) At lower resolution bandwidths(below 30kHz)the measurement time per point starts to increase due to the resolution filter implementation. Careful use of the FAST sweeping mode may reduce this time increase. 6)The performance limitations of the shielding and the filters may lead to certain images and spurs being visible but certain functions like spur suppression and switching to below. IF may help detect and/or reduce these spurs and images 7)Below 0. 1MHz the sensitivity starts to reduce. 8)Below 1MHz it is recommended to disable the AGC and possibly enable the LNA to get the best measurement quilty Question: Q .Am I limtied to maximum 290 scan points? A.In standalone operation the scan can use many measurement points with a large span and low RBW but the display is always using a maximum of 290 points. When using the tinysa in combination with a Pc the amount of points is unlimited. The windows control program supports scanning with up to 30000 measurement points A.When unexplained interference occurs causing +/-1dB eliminated by offsetting the zero span center frequency with 1/4 RB Q . How are the additional inserted measurements consolidated into one displayed measurement? A. The displayed measurement is the maximum additional measurements to ensure the level of a signal falling within only one measurement is correctly displayed. Q. Can I inspect the SSB modulation of my transmitter？ A. As the minimum RBW is 2. 7kHZ it is impossible to look at details inside a 2.7kHZ wide SSB signal. With the careful setup, it is just possible to check the alternate sideband section or see the carrier rejection.
