Low input spectrum analyser mode (SMA 1)

• Input frequency range 100 kHz to 350 MHz
• Dynamic range/sensitivity of 70 dB
• Input impedance 50 ohms when input attenuation is set to 10 dB or more
• Manual and automatic input attenuation selectable between 0 dB and 31 dB in 1 dB steps
• Absolute maximum input level +10dBm with 0dB internal attenuation
• Absolute maximum input power +20dBm with 30dB internal attenuation and very short measurement time
• Maximum input power +0 dBm with internal attenuation in automatic mode
• For best measurements, keep input power below -25dBm
• Third order modulation (IIP3) input intercept point of +15dBm with 0dB internal attenuation
• Compression point of 1dB at -1dBm with 0dB internal attenuation
• Power detector resolution of 0.5dB and linearity to frequency of +/- 2dB
• Power accuracy after calibration of +/- 2 dB
• Lowest discernible signal at 30 MHz using 30 kHz resolution bandwidth of -102dBm
• Frequency accuracy equal to selected resolution bandwidth
• Phase noise of -108dB/Hz at 100kHz offset and -115dB/Hz at 1MHz offset
• Sweep-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 57 resolution filters
• On-screen resolution of 51, 101, 145 or 290 measurement points
• Scanning speed of over 1000 points/second using the most important resolution filters
• Automatic optimisation of the actual scan points to ensure coverage of the entire scan range, regardless of the resolution bandwidth chosen.
• Noise suppression option to assess whether certain signals are internally generated or actually present in the input signal.
• After a small hardware modificationThe demodulated sound can be listened to (AM only).

High inputspectrum analyser mode (SMA 2)

• Input frequency range 240 MHz to 960 MHz
• Dynamic range/sensitivity of 50 dB
• Frequency-dependent input impedance +/- 50 ohms
• Absolute maximum unattenuated input level of +10dBm

• Compression point 1dB at -6dBm without internal attenuation
• Manually selectable resolution filters of 3, 10, 30, 100, 300, 600 kHz. Automatic selection of one of 57 resolution filters
• As there is no input band filter, strong input signals outside the 240MHz to 960MHz range can distort in-band signals.
• Power detector resolution of 0.5dB and linearity as a function of frequency of +/-2dB
• Absolute power level accuracy after power level calibration of +/- 2dB

• Optional 25dB to 40dB frequency-dependent input attenuator. Power level error with this attenuator activated increases by +/- 10dB
• On-screen resolution of 51, 101, 145 or 290 measurement points
• Scan speed of over 1000 points/second using the higher resolution filters
• Automatic optimisation of the current scan points to ensure coverage of the entire scan range, regardless of the resolution bandwidth selected
• After a small hardware modificationdemodulated sound (AM/FM) can be heard
