描述：The 4080 series models are versatile, laboratory grade synthesized function generators with a wide frequency range up to 120 MHz. Direct digital synthesis (DDS) techniques are used to create stable, accurate output signals for all 27 built-in standard and complex (arbitrary) waveforms. The generators produce high purity, low distortion sine waves, and provide a full suite of analog modulation capabilities including AM, FM, FSK, PSK, pulse modulation, burst mode, and linear/logarithmic sweep combined with multiple trigger modes. These function generators are ideal for many general-purpose test and bench applications or for use in training and education. . Wide frequency range of 1 uHz up to 120 MHz for Sine . Sine and square output plus 27 additional built-in arbitrary waveforms . Clean and stable output of very small signals down to the 1 mV to 10 mV range (50 ohms) . Support of internal & external modulation sources inc. internal, external, & gated trigger sources . Convenient data input via numeric keypad or knob . Adjust modulation parameters precisely and over a wide range . Fully programmable via the standard RS232 interface using SCPI compatible commands . 100 MHz Universal Counter with frequency measurement and totalize function
