EXCEPTIONAL PERFORMANCE MODEL COMPARISON Max frequency (square/ pulse) Vertical bits / Sample rate Noise bandwidth HIGHER FREQUENCIES The TGF4000 Series out-performs other generators in its price range by offering high purity sine waves up to 240MHz and square waves up to 100MHz, with low harmonic distortion and low phase noise, audio band THD is significantly better than similar generators at just 0.05%. EXCEPTIONAL FREQUENCY PRECISION The frequency of these waveforms can be set with up to 15 digits or one micro hertz of resolution. The DDS based frequency generation system uses a high...

EXTENSIVE DIGITAL & ANALOG MODULATIONS A large set of modulation types are built-in including AM, FM, PM, FSK, ASK, BPSK, PWM and SUM. All standard and arbitrary waveforms can be modulated as the carrier, although Noise, Pulse and PRBS are limited to AM, ASK and SUM modulations plus PWM for Pulse. INTERNAL DIGITAL MODULATIONS AM, FM, PM, PWM and SUM modulations can use an internal modulation source based upon any standard or arbitrary waveform type or Noise. A very wide modulation frequency range of 1µHz to 10MHz can be used. FSK, ASK, and BPSK use a square wave modulation signal adjustable...

EFFICIENT WORKING GRAPHIC USER INTERFACE (GUI) The TGF4000 series is equipped with a 4.3 inch high resolution colour screen, providing added efficiency and clarity when carrying out complex testing. The graphic display demonstrates a quick visual insight into the waveform through the specifically colour coded graph, ensuring accurate and reliable results. Graphs for both channels can be displayed side by side for easy comparison or alongside a detailed description of the settings selected. Each channel has a unique set colour to provide instant recognition of the output channel selected...

TWO CHANNEL OPERATION The two channels are identical with no performance limitations giving maximum flexibility and value for money. ff INDEPENDENT CHANNEL OPERATION The two channels can be operated completely independently as if they were two separate generators. (Note that external trigger and external modulation inputs are shared). ff RELATIVE PHASE The relative phase can be set from -360 degrees to +360 degrees with 0.001o resolution. Pressing the ‘align’ key phase synchronises the two channels with the specified phase offset. ff COUPLED OPERATION The frequencies of the two channels can...

ENHANCED CONNECTIVITY FULL REMOTE CONTROL GPIB (OPTIONAL) All functions of the generators can be controlled from the digital interfaces. Arbitrary waveform data can also be loaded using these interfaces. The GPIB interface is compliant with IEEE-488.1 and IEEE-488.2. GPIB remains a widely used interface for system applications. The TGF4000 has a built-in LXI compliant web server which provides information on the unit and allows it to be configured over the LAN, quickly allowing the unit to be controlled via PC or tablet at no extra cost. Simple command line control from the browser is also...

FREQUENCY REFERENCE SYNC OUTPUT The generators use a high quality TCXO crystal as the internal frequency reference providing 1ppm accuracy and stability. If a higher accuracy or stability is required, an external 10MHz reference signal (from an off-air standard for example) can be applied to the Ref. Clock input. The internal 10MHz clock is available as a rear panel output for synchronisation with external equipment. Channel 2 can be configured to be a Sync output for channel 1. Sync can be chosen to perform a variety of tasks depending upon the waveform type and the application. OTHER...
