and high quality Feature: Made of fine quality material, practical, easy to operate and use, has a long service life. Spectrum analyzer with two inputs, fine quality MF/HF/VHF input for 0.1MHz-350MHz, lesser quality UHF input for 240MHz-960MHz. Switchable resolution bandpass filters for both ranges between 2.6KHz and 640KHz. Color display showing 290 scan points covering up to the full low or high frequency range. Input step attenuator from 0dB to 31dB for the MF/HF/VHF input. When not used as spectrum analyzer it can be used as signal generator, MF/HF/VHF sinus output between 0.1MHz-350MHz, UHF square wave output between 240MHz-960MHz. A built-in calibration signal generator that is used for automatic self test and low input calibration. Connected to a PC via USB it becomes a PC controlled spectrum analyzer. Rechargeable battery allowing a minimum of at least 2 hours portable use. Low input mode spec: 1.Input frequency range from 100kHz to 350MHz 2.Input impedance 50 ohm when input attenuation set to 10dB or more. 3.Selectable manual and automatic input attenuation between 0dB and 31dB in 1 dB steps 4.Absolute maximum input level without attenuation of +10dBm 5.Absolute maximum input power with 30dB attenuation of +20dBm for short period 6.Input Intercept Point of third order modulation products (IIP3) with 0dB attenuation of +15dBm 7.1dB compression point at +2dBm with 0dB attenuation 8.Power detector resolution of 0.5dB and linearity for versus frequency of +/-1dB 9.Absolute power level accuracy after power level calibration of +/- 1dB 10.Lowest discernible signal using a resolution bandwidth of 30kHz of -102dBm 11.Frequency accuracy equal to the selected resolution bandwidth 12.Phase noise of -90dB/Hz at 100kHz offset and -115dB/Hz at 1MHz offset 13.Spur free dynamic range when using a 30kHz resolution bandwidth of 70dB 14.Manually selectable resolution filters of 3, 10, 30, 100, 300, 600kHz. Automatic selection of one of the 57 resolution filters. 15.On screen resolution of 145 or 290 measurement points. 16.Scanning speed of over 1000 points/second using largest resolution filters. 17.Automatic optimization of actual scanning points to ensure coverage of the whole scan range regardless of the chosen resolution bandwidth 18.Spur suppression option for assessing if certain signals are internally generated or actually present in the input signal High input mode spec: 1.Input frequency range from 240MHz to 960MHz 2.As there is no input bandfilter strong signals outside the 240MHz to 960MHz range can cause distortion of the in band signals 3.Absolute maximum input level without attenuation of +10dBm 4.Input Intercept Point of third order modulation products (IIP3) of -5dBm 5.1dB compression point at -6dBm with 0dB attenuation 6.Power detector resolution of 0.5dB and linearity for versus frequency of +/-1dB 7.Absolute power level accuracy after power level calibration of +/- 1dB 8.Lowest discernible signal using a resolution bandwidth of 30kHz of -115dBm 9.Frequency accuracy equal to the selected resolution bandwidth 10.Spur free dynamic range when using a 30kHz resolution bandwidth of 50dB 11.
