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.
