2.8-inch handheld spectrum analyser with PC connectivity 100kHz–350MHz tinySA signal generator
Input frequency range: 100kHz to 350MHz
Pre-amplifier attenuator: 0dB to 31dB, 1dB steps for manual and automatic input attenuation
Absolute maximum input level: +10dBm without attenuation
Damage level: +20dBm
Third-order intercept point (11P3) input: +24dBm at 0dB attenuation
1dB Compression Point: +2dBm at 0dB attenuation
Power Detector Resolution: 0.5dB ±1dB
Minimum Detectable Signal: -102dBm @ 30kHz RBW
Phase Noise: -90dB/Hz at 100kHz offset, -115dB/Hz at 1MHz offset
Spurious noise below -70 dBm when using 30 kHz resolution bandwidth B.
Resolution filters manually selectable at 3, 10, 30, 100, 300, 600 kHz. Automatic selection from 57 resolution filters.
On-screen resolution displays 51, 101, 145, or 290 measurement points.
With the maximum resolution filter, the scan rate exceeds 1000 points per second.
Actual scan points are automatically optimised to ensure full coverage of the scan range, regardless of the selected resolution bandwidth.
Spurious suppression options are available to assess whether certain signals are internally generated or genuinely present in the input signal.
High Input Mode Specifications (High Input Mode utilises a second receiver for low-IF reception without pre-image and spurious filters)
Input frequency range: 240 MHz to 960 MHz
Input impedance is frequency-dependent, deviating from 50 ohms.
Due to the absence of an input bandpass filter, strong input signals outside the 240 MHz to 960 MHz range may cause in-band signal distortion.
Absolute maximum input level without attenuation: +10 dBm.
Input intercept point at -5 dBm for third-order modulation products (1IP3).
1dB compression point at -6dBm, without attenuation.
Power detector resolution is 0.5dB, with frequency linearity of +/-1dB.
Absolute power level accuracy after power level calibration is +/-1dB.
Minimum detectable signal at 30kHz resolution bandwidth: -115dBm.
Frequency accuracy equals the selected resolution bandwidth.
No sideband dynamic range when using 30kHz resolution bandwidth at 50dB.
Resolution filters of 3, 10, 30, 100, 300, 600kHz may be manually selected. Automatically selects one of 57 resolution filters.
Optional frequency-dependent input attenuator from 25dB to 40dB. Activating this attenuator increases power level error to +/-10dB.
Screen resolution of 51, 101, 145, or 290 measurement points.
Scanning speed exceeds 1000 points/second using the maximum resolution filter.
Automatically optimises actual scan points to ensure full coverage across the entire scan range, regardless of selected resolution bandwidth.
Low Output Mode Specifications
Sine wave output with harmonics below -40dB relative to fundamental frequency.
Output frequency range from 100kHz to 350MHz (minimum frequency step 312.5Hz)
Output level adjustable in 1dB steps between -76dBm and -6dBm
Selectable AM, narrowband FM and wideband modulation, or sweep output across a selectable frequency span (AM modulation is achieved via rapid front-end attenuator changes; FM modulation is achieved via rapid output frequency modification. Neither constitutes standard precise modulation. Suitable for basic walkie-talkie reception testing but not as a precise reference).
High Output Mode Specifications
Square Wave Output
Output frequency range from 240MHz to 960MHz (minimum frequency step 312.5Hz)
Output level selectable in variable increments between -38dBm and +13dBm (higher attenuation achieved via RF switch leakage; leakage increases with frequency, introducing significant error)
Selectable narrowband FM and wideband modulation, or slow frequency sweep within selectable ranges (FM modulation is achieved via rapid output frequency modification, not standard precise modulation; suitable for basic walkie-talkie reception testing but not as an accurate reference) Reference Signal Generator Specifications (for self-testing or providing reference clock to external devices) Selectable square wave output, base value -25dBm, connected to high input/output.
Frequency settable to 1MHz, 2MHz, 4MHz, 10MHz, 15MHz or 30MHz. Limitations
Given the careful balance between performance and cost in the selection of internal components within the tinySA, one must be aware of its significant limitations when compared to professional spectrum analysers. The internal phase noise imposes a clear lower limit on phase noise measurements.
The minimum resolution bandwidth of 3kHz prevents observation of further spectral details.
Image rejection at high inputs (240MHz to 960MHz) is severely limited, and only a single-stage built-in attenuator is available, making complex signals difficult to distinguish.
The high-input selectable attenuator is frequency-dependent, varying between 25dB and 40dB.
At lower resolution bandwidths (below 30kHz), scanning speeds become sluggish.
Limitations in shielding and filter performance may render certain images and spurious signals visible. The tinySA provides a spurious elimination menu which experienced users may configure to reduce spurious emissions, though potential uncertainties should be acknowledged.
Sensitivity begins to decrease below 0.1MHz.
Below 1MHz, it is recommended to disable AGC and enable the LNA where possible to achieve optimal measurement quality.
The tinySA is not an SDR receiver and does not provide any reception demodulation functionality! The tinySA is not a sweep generator and does not provide a tracking source output. For sweep functionality, please use the NanoVNA!
