Specification
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 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 +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

the demodulated audio

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.
