Specification

User interface:

* 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.

The input/output specification of the tinySA is split over the 4 modes

Low input mode spec:

* Input frequency range from 100kHz to 350MHz
* Input impedance 50 ohm when input attenuation set to 10dB or more.
* Selectable manual and automatic input attenuation between 0dB and 31dB in 1 dB steps
* Absolute maximum input level without attenuation of +10dBm
* Absolute maximum input power with 30dB attenuation of +20dBm for short period
* Input Intercept Point of third order modulation products (IIP3) with 0dB attenuation of +15dBm
* 1dB compression point at +2dBm with 0dB attenuation
* Power detector resolution of 0.5dB and linearity versus frequency of +/-1dB
* Absolute power level accuracy after power level calibration of +/- 1dB
* Lowest discernible signal using a resolution bandwidth of 30kHz of -102dBm
* Frequency accuracy equal to the selected resolution bandwidth
* Phase noise of -90dB/Hz at 100kHz offset and -115dB/Hz at 1MHz offset
* Spur free dynamic range when using a 30kHz resolution bandwidth of 70dB
* Manually selectable resolution filters of 3, 10, 30, 100, 300, 600kHz. Automatic selection of one of the 57 resolution filters.
* On screen resolution of 145 or 290 measurement points.
* Scanning speed of over 1000 points/second using largest resolution filters.
* Automatic optimization of actual scanning points to ensure coverage of the whole scan range regardless of the chosen resolution bandwidth
* Spur suppression option for assessing if certain signals are internally generated or actually present in the input signal

High input mode spec:

* Input frequency range from 240MHz to 960MHz
* As there is no input bandfilter strong signals outside the 240MHz to 960MHz range can cause distortion of the in band signals
* Absolute maximum input level without attenuation of +10dBm
* Input Intercept Point of third order modulation products (IIP3) of -5dBm
* 1dB compression point at -6dBm with 0dB attenuation
* Power detector resolution of 0.5dB and linearity versus frequency of +/-1dB
* Absolute power level accuracy after power level calibration of +/- 1dB
* Lowest discernible signal using a resolution bandwidth of 30kHz of -115dBm
* Frequency accuracy equal to the selected resolution bandwidth
* Spur free dynamic range when using a 30kHz resolution bandwidth of 50dB
* Selectable (automatic and manual) resolution filters of 3, 10, 30, 100, 300 and 600kHz
* Optional 25dB to 40dB frequency dependent input attenuator. The power level error with this attenuator activated increases to +/- 15dB
* On screen resolution of 145 or 290 measurement points.
* Scanning speed of over 1000 points/second using largest resolution filters.
* Automatic optimization of actual scanning points to ensure coverage of the whole scan range regardless of the chosen resolution bandwidth

Low output mode spec:

* Sinus output with harmonics below -40dB of fundamental
* Output frequency range from 100kHz to 350MHz
* Output level selectable in 1dB steps between -76dBm and -6dBm
* Optional AM, narrow FM and wide FM modulation or slow sweep over selectable frequency span

High output mode spec:

* Square wave output
* Output frequency range from 240MHz to 960MHz
* Output level selectable in variable increments between -38dBm and +13dBm
* Optional narrow FM and wide FM modulation or slow sweep over selectable frequency span

Reference generator spec:

* Optional square wave output with fundamental at -25dBm connected to high input/output
* Frequency can be set to 1MHz, 2MHz, 4MHz, 10MHz, 15MHz or 30MHz.

Battery spec:

* Charging time max 1 hour on 500mA minimum USB port or USB charger
* Operation on fully charged battery for at least 2 hours

Package inclued:
TinySA 2.8" Spectrum analyzer *1
20cm sma-sma rg174 rf cabe *2
USB Type-C Data Cable *1
Hand rope *1
SMA female to female connector *1
SMA telescopic antenna *1


スパン20kHz RBW 3kHz では占有周波数帯幅付近の測定は無理そう(T_T)
激安スペアナ君にその性能を要求するのは無理です(送料込みで約6000円ですから)



スパン 1MHz RBW 3kHz では、よいですね~ (^^)




ちなみに本物のスペアナで測定してみると・・・・
スパン 20kHz RBW 3kHz 残念ながら本物のスペアナでも
占有周波数帯幅付近の測定は無理~




スパン 20kHz RBW 300Hz 本物のスペアナが本気をだすと占有周波数帯幅付近の測定ができます。
