Specifications:
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 (with some limitations down to 10kHz).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 of +10dBm with 0dB internal attenuation.Absolute maximum short term peak input power of +20dBm with 30dB internal attenuation.Suggested maximum input power of +5dBm with internal attenuation in automatic mode.For best measurements keep input power below -25dBm.Input Intercept Point of third order modulation products (IIP3) of +15dBm with 0dB internal attenuation.1dB compression point at -1dBm with 0dB internal 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 51, 101, 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.After a small HW modification it is possible to Listen to the demodulated audio.
High input mode spec:Input frequency range from 240MHz to 960MHz.Input impedance is frequency dependent and deviates from 50 ohm.As there is no input band filter, strong input 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 with no internal attenuation.1dB compression point at -6dBm with no internal 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.Manually selectable resolution filters of 3, 10, 30, 100, 300, 600kHz. Automatic selection of one of the 57 resolution filters.Optional 25dB to 40dB frequency dependent input attenuator. The power level error with this attenuator activated increases to +/- 10dB.On screen resolution of 51, 101, 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.After a small HW modification it is possible to Listen to the demodulated audio.
Low output mode spec:Sinus output with harmonics below -40dB of fundamental.Output frequency range from 100kHz to 350MHz.Level accuracy +/- 2dB over the whole output frequency range.Output frequency resolution either 156Hz below 47MHz output or 312Hz above 47MHz output.Output level selectable in 1dB steps between -76dBm and -6dBm.Optional AM, narrow FM and wide FM modulation with frequencies between 50Hz and 6kHz or slow sweep over selectable frequency span.Optional output level sweep over maximum the entire output level range.
High output mode spec:Square wave output.Output frequency range from 240MHz to 960MHz.Output frequency resolution either 156Hz below 480MHz output or 312Hz above 480MHz output.Output level selectable in variable increments between -38dBm and +9dBm.Optional narrow FM and wide FM modulation with frequencies between 50Hz and 6kHz 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.
Warranty: 24 months.
