Review TinySA - Miklor

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
