Phase noise is -90dB/Hz at 100kHz offset and -115dB/Hz at 1MHz offset.
No spur dynamic range when using a 30kHz resolution bandwidth of 70dB.
3, 10, 30, 100, 300, 600kHz resolution filters can be manually selected. One of 57 resolution filters is automatically selected.
The resolution on the screen is 51, 101, 145 or 290 measurement points.
With the maximum resolution filter, the scan speed exceeds 1000 points/sec.
The actual scan point is automatically optimized to ensure that the entire scan range is covered, regardless of the selected resolution bandwidth.
Spur rejection option to evaluate whether certain signals are internally generated or actually present in the input signal.
High Input Mode Specifications: (High Input Mode is low IF reception with a second receiver without pre-image and spurious filters)
Input frequency range: 240MHz to 960MHz
Input impedance is frequency dependent and deviates from 50 ohms.
Since there is no input band filter, strong input signals outside the 240MHz to 960MHz range can cause in-band signal distortion.
Absolute maximum input level without attenuation +10dBm.
Input a third-order modulation product (IIP3) with an intercept point of -5dBm.
1dB compression point at -6dBm, no 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 30kHz RBW - 115dBm minimum discernible signal.
Frequency accuracy equal to selected resolution bandwidth
No spur dynamic range when using a 30kHz resolution bandwidth of 50dB.
3, 10, 30, 100, 300, 600kHz resolution filters can be manually selected. One of 57 resolution filters is automatically selected.
Optional 25dB to 40dB frequency dependent input attenuator. After activating this attenuator, the power level error increases to +/-10dB.
Screen resolutions of 51, 101, 145 or 290 measurement points.
With the maximum resolution filter, the scan speed exceeds 1000 points/second.
The actual scan point is automatically optimized to ensure that the entire scan range is covered, regardless of the selected resolution bandwidth.
Low Output Mode Specifications:
Sine wave output, the harmonics are lower than -40dB of the fundamental wave.
Output frequency range from 100kHz to 350MHz (minimum frequency step 312.5Hz)
Output level can be stepped between -76dBm and -6dBm in 1dB steps
Selectable AM, narrowband FM and wideband modulation or swept output over selectable frequency span
(AM modulation function is realized by fast changing pre-attenuator, FM modulation is realized by fast changing output frequency, not standard accurate modulation, can be used for simple walkie-talkie receiving test, but cannot be used as an accurate reference)
High Output Mode Specifications
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 (higher attenuation is achieved using RF switch leakage, the attenuation becomes larger as the frequency increases, and there will be a relatively large error)
Narrowband FM and wideband modulation can be selected or slow frequency sweep in the selectable frequency range (FM modulation is realized by rapidly modifying the output frequency, not standard accurate modulation, which can be used for simple walkie-talkie receiving test, but cannot be used as an accurate reference )
Reference generator specifications (for self-test or to output a reference clock for external devices)
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.
limitation
Since the selection of tinySA`s internal components is a careful balance between performance and cost, you must be aware that tinySA has significant limitations compared to professional spectrum analyzers.
Internal phase noise sets a well-defined lower limit for phase noise measurements.
The minimum resolution bandwidth of 3kHz makes it impossible to see more spectral detail.
Image rejection at high inputs (240MHz to 960MHz) is very limited, and there is only one level of optional built-in attenuator, which makes complex signals difficult to resolve.
High input selectable input attenuator is frequency dependent and varies between 25dB and 40dB.
At lower resolution bandwidths (below 30kHz) the sweep speed will be slow.
The performance limitations of shielding and filters may cause some images and spurs to be visible, tinySA offers a spurious cancellation menu that experienced users can set to reduce spurs, but need to be aware of possible uncertainties.
Below 0.1MHz, the sensitivity begins to decrease.
Below 1MHz, it is recommended to disable the AGC and enable the LNA if possible for the best measurement quality.
When using the supplied telescopic antenna or low RBW, be aware of tinySA MCU interference at 48MHz and its harmonics.
tinySA is not an SDR receiver and does not provide any receive demodulation function!
tinySA is not a frequency sweeper and does not provide tracking source output. If you need frequency sweeping function, please use NanoVNA!
