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 +0dBm 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 +/-2dB
- Absolute power level accuracy after power level calibration of +/- 2dB
- Lowest discernible signal at 30MHz using a resolution bandwidth of 30kHz of -102dBm
- Frequency accuracy equal to the selected resolution bandwidth
- Phase noise at 30MHz of -90dB/Hz at 100kHz offset and -120dB/Hz at 1MHz offset
- Spur free dynamic range when using a 30kHz resolution bandwidth of 70dB
- Manually selectable resolution filters with a width 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 (AM only)
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 +/-2dB
- Absolute power level accuracy after power level calibration of +/- 2dB
- 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:
- Sine wave 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 5kHz 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 -26dBm connected to high input/output
- Frequency can be set to 1MHz, 2MHz, 4MHz, 10MHz, 15MHz or 30MHz.
Battery spec:
