Input frequency range: 100kHz to 900MHz in normal mode, up to 12GHz in ULTRA mode. Input impedance is 50 ohms when input attenuation is set to 10dB or higher. Manual and automatic input attenuation selectable in 1dB steps from 0dB to 31dB. Absolute maximum input level is +6dBm at 0dB internal attenuation; Absolute maximum short-term input power is +20dBm at 30dB internal attenuation; Recommended maximum input power in auto mode is +0dBm, internal attenuation: Power detector resolution is 0.5dB, frequency linearity is +/-2dB below 5.3GHz, +/-5dB between 5.3GHz and 6GHz Minimum identifiable signal is -102dBm at 30MHz (without LNA); Use -145dBm at 30kHz frequency, 200Hz ; frequency accuracy equal to Signal Generator Specifications: Sine wave output with harmonics -40dB below fundamental, frequency range 100kHz to 800MHz. Output level selectable in 1dB steps from -110dBm to -20dBm. Two output modes selectable above 800MHz:Cleanest Signal Mode: Square wave, up to 4.4GHz, coarser frequency steps, lower output level accuracy.Highest Accuracy Mode: Reduced harmonics, possible strong spurs up to 5.4GHz, finer frequency resolution below 800MHz, fine self-adjustment of output level steps. Output Frequency Resolution: 57.2Hz Selectable AM or FM Modulation Frequency: 50Hz to 5KHz (AM) or 1KHz (FM), or swept AM modulation over a selectable frequency range. Modulation Depth: 10% to 100%. FM Deviation: 1kHz to 300kHz. Reference Clock Generator: Selectable square wave output with fundamental at -35.6dBm, connected to calibration output. Frequency can be set to 1MHz, 2MHz, 4MHz, 10MHz, 15MHz, or 30MHz.
