Description

Tiny Spectrum Analyzer Shell size: 58.7mm x 91.3mm x 17.1mm (excluding protrusion) Frequency accuracy: 2ppm, Frequency stability: 1ppm Display: 2.8 “TFT (320 x240) resistance touch screen USB interface: USB type-C communication mode: CDC (serial) Power supply: USB 5V 150mA, built-in 650mah battery, maximum charging current 300mA, charging time 1 hour 2 hours Gross weight per unit: 0.25 kg Package size: 19.5 * 12.5 * 2.5cm Built in battery: 650mah Low input mode specification: Input frequency range: 100kHz 350MHz Front attenuator: 0db-31db, step 1dB, manual and automatic input attenuation Absolute maximum input level: + 10dBm without attenuation Damage level + 20dbm Third order modulation (IIP3) input cut-off point: + 15dBm at 0dB attenuation 1dB compression point: + 2dbm at 0dB attenuation Power detector resolution: 0.5dB + / – 1dB. Minimum identifiable signal: -102dBm@30kHz RBW The phase noise is – 90dB / Hz at 100kHz and – 115dB / Hz at 1MHz. When using 30kHz resolution bandwidth of 70dB, there is no branch line dynamic range. The resolution filters of 3, 10, 30, 100, 300 and 600 kHz can be selected manually. Automatically select one of 57 resolution filters. The resolution on the screen is 51, 101, 145 or 290 measurement points. Using the filter with the maximum resolution, the scanning speed exceeds 1000 points / second. Automatically optimize the actual scan points to ensure coverage of the entire scanning range, regardless of the resolution bandwidth selected. Branch suppression option, used to evaluate whether some signals are generated internally or actually exist in the input signal. High input mode specification: (high input mode is a low if reception using a second receiver, without front mirror image and spurious filter) Input frequency range: 240mhz to 960MHz The input impedance is frequency dependent and deviates from 50 ohm. Since there is no input band filter, strong input signals beyond 240mhz to 960MHz will cause in band signal distortion. Absolute maximum input level without attenuation + 10dBm. The third-order modulation product (IIP3) with a cut-off point of – 5dBm is input. The 1dB compression point is – 6dbm without attenuation. The power detector has a resolution of 0.5dB and a frequency linearity of + / – 1dB. The absolute power level accuracy after power level calibration is + / – 1dB. Use resolution bandwidth of 30kHz – 115dbm minimum identifiable signal. The frequency accuracy is equal to the selected resolution bandwidth When 30kHz resolution bandwidth is 50dB, there is no branch line dynamic range. The resolution filters of 3, 10, 30, 100, 300 and 600 kHz can be selected manually. Automatically selects one of 57 resolution filters. Optional 25dB to 40dB frequency dependent input attenuator. When the attenuator is activated, the power level error increases to + / – 10dB. The screen resolution is 51, 101, 145 or 290 measurement points. Using the filter with the maximum resolution, the scanning speed exceeds 1000 points / second. Automatically optimize the actual scan points to ensure coverage of the entire scanning range, regardless of the resolution bandwidth selected. Low output mode specifications: The output of sine wave is lower than – 40dB of fundamental wave. Output frequency range from 100kHz to 350MHz (minimum frequency step 312.5hz) The output level can be stepped in 1dB between – 76dbm and – 6dbm It can select am, narrowband FM and wideband modulation, or sweep output on optional frequency span (AM modulation function is realized by rapidly changing pre attenuator, FM modulation is realized by rapidly modifying output frequency, not standard precise modulation, which can be used for simple intercom receiving test, but can not be used as accurate reference) High output mode specification Square wave output Output frequency range from 240mhz to 960MHz (minimum frequency step 312.5hz) The output level can be selected in variable increments between – 38dbm and + 13dbm (the higher attenuation is achieved by RF switch leakage, and the attenuation increases with the increase of frequency, and there will be large error) Narrow band FM and broadband modulation can be selected, or the frequency can be swept slowly in the optional frequency range (FM modulation is realized by rapidly modifying the output frequency, not standard precise modulation, which can be used for simple intercom receiving test, but can not be used as an accurate reference) Reference signal generator specification (for self-test or output reference clock for external equipment) Optional square wave output, base value – 25dbm, connected to high input / output. The frequency can be set to 1MHz, 2MHz, 4MHz, 10MHz, 15MHz or 30MHz. limitations Because the choice of internal components in tinysa achieves a careful balance between performance and cost, you must be aware of the limitations of tinysa compared with professional analyzers. Internal phase noise sets a definite lower limit for phase noise measurement. The minimum resolution bandwidth of 3kHz makes it unable to see more details. High input (240mhz to 960MHz) has very limited image rejection and only one stage of optional built-in attenuator, which makes complex signals difficult to distinguish. High input optional input attenuators are frequency dependent and vary between 25dB and 40dB. In the low resolution bandwidth (below 30kHz), the scanning speed will be very slow. The performance limitation of shielding and filter may cause some mirror image and spurious to be visible. Tinysa provides spurious elimination menu, which can be set by experienced users to reduce spurious, but pay attention to possible uncertainties. When it is lower than 0.1MHz, the sensitivity begins to decrease. Below 1MHz, it is recommended to disable AGC and enable LNA if possible to obtain the best measurement quality. When using the provided telescopic antenna or low RBW, pay attention to the interference of tinysa MCU on 48mhz and its harmonics. Tinysa is not a SDR receiver and does not provide any receiving and demodulation functions! Tinysa is not a frequency sweeper and does not provide tracking source output.
