• 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

• Lowest discernible signal using a resolution bandwidth of 30kHz of -102dBm
• Frequency accuracy equal to the selected resolution bandwidth
• Phase noise of -90dB/Hz at 100kHz offset and -115dB/Hz at 1MHz offset

• 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
