4078GPIB产品概述
Point-by-Point Signal IntegrityThe 4075B Series Arbitrary/Function Waveform Generators are versatile high-performance single- and dual-channel arbitrary waveform generators with large arbitrary memory depth. The instruments provide variable output voltages from 0 to 10 Vp-p into 50 ohms or up to 20 Vp-p into open circuit and a continuously variable DC offset that allows the output to be injected directly into circuits at the correct bias level.These generators combine the benefits of DDS (direct digital synthesis) and true AWG (arbitrary waveform generator) architectures without the limitations of either. Standard waveforms such as sine, square, and triangle are generated with a DDS chip, delivering great frequency resolution at a low cost. Custom arbitrary waveform generation is implemented with a true point-by-point design, offering improved signal integrity by producing significantly less jitter and distortion compared to a DDS-only architecture. This point-by-point generation capability allows these instruments to be used for simulating reliable clock signals, generating triggers, or validating serial data buses.Additionally, these generators can be used with waveform editing software WaveXpress to create complex arbitrary waveforms.Extensive features such as internal or external AM, FM, and FSK modulation along with versatile sweep capabilities and variable edge pulse generation make these generators suitable for a wide range of applications.ApplicationsThese generators are suitable for applications such as electronic design, sensor simulation, functional test, or generation of I/Q modulated signals."Features14-bit, 200 MSa/s, 16 Mpts arbitrary waveform generatorGenerate sine waveforms up to 30 MHzBright color LCD displayLinear and logarithmic sweepAM/FM/FSK modulationVariable DC offsetAdjustable duty cycleOutput ON/OFF buttonInternal/external triggeringGate and burst modeFully programmable markersStore/recall up to 49 instrument settingsStandard USBTMC interface (all models) and GPIB interface (50 MHz & 80 MHz models only) supporting SCPI\ commandsClosed case calibrationShort circuit protection for resistive and capacitive loads on outputs and overvoltage protection on inputsDual-channel modelsBoth channels offer full functionality and all parameters can be set independentlySynchronize the phase of both channels with the push of a button"
