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

Low input mode spec:

x Input frequency range from 100kHz to 350MHz

x Input impedance 50 ohm when input attenuation set to 10dB or more.

x Selectable manual and automatic input attenuation between 0dB and 31dB in 1 dB steps

x Absolute maximum input level without attenuation of +10dBm

x Absolute maximum input power with 30dB attenuation of +20dBm for short period

x Input Intercept Point of third order modulation products IIP3 with 0dB attenuation of +15dBm

x 1dB compression point at +2dBm with 0dB attenuation

x Power detector resolution of 0.5dB and linearity versus frequency of +/-1dB

x Absolute power level accuracy after power level calibration of +/- 1dB

x Lowest discernible signal using a resolution bandwidth of 30kHz of -102dBm

x Frequency accuracy equal to the selected resolution bandwidth

x Phase noise of -90dB/Hz at 100kHz offset and -115dB/Hz at 1MHz offset

x Spur free dynamic range when using a 30kHz resolution bandwidth of 70dB

x Manually selectable resolution filters of 3, 10, 30, 100, 300, 600kHz. Automatic selection of one of the 57 resolution filters.

x On screen resolution of 145 or 290 measurement points.

x Scanning speed of over 1000 points/second using largest resolution filters.

x Automatic optimization of actual scanning points to ensure coverage of the whole scan range regardless of the chosen resolution bandwidth

x Spur suppression option for assessing if certain signals are internally generated or actually present in the input signal

High input mode spec:

x Input frequency range from 240MHz to 960MHz

x As there is no input bandfilter strong signals outside the 240MHz to 960MHz range can cause distortion of the in band signals

x Absolute maximum input level without attenuation of +10dBm

x Input Intercept Point of third order modulation products IIP3 of -5dBm
x 1dB compression point at -6dBm with 0dB attenuation
x Power detector resolution of 0.5dB and linearity versus frequency of +/-1dB
x Absolute power level accuracy after power level calibration of +/- 1dB
x Lowest discernible signal using a resolution bandwidth of 30kHz of -115dBm
x Frequency accuracy equal to the selected resolution bandwidth
x Spur free dynamic range when using a 30kHz resolution bandwidth of 50dB
x Selectable automatic and manual resolution filters of 3, 10, 30, 100, 300 and 600kHz
x Optional 25dB to 40dB frequency dependent input attenuator. The power level error with this attenuator activated increases to +/- 15dB
x On screen resolution of 145 or 290 measurement points.
x Scanning speed of over 1000 points/second using largest resolution filters.
x Automatic optimization of actual scanning points to ensure coverage of the whole scan range regardless of the chosen resolution bandwidth

Low output mode spec:

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

High output mode spec:

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

Reference generator spec:

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

Battery spec:

x Charging time max 1 hour on 500mA minimum USB port or USB charger

x Operation on fully charged battery for at least 2 hours
