HiSmart / ED-TV991211
Spectrum Analyzer
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 afte
