AIM & THURLBY THANDAR INSTRUMENTS TG1006 10MHz DDS Function Generator with sweep and 120MHz counter 1mHz to 10MHz continuous frequency range DDS frequency generation for accuracy and stability Wide range phase continuous sweep, linear or logarithmic Modulation modes of AM, FSK and Frequency List 120MHz auto-ranging seven digit frequency meter www.aimtti.com aimtti.co.uk aimtti.usTG1006 - 10MHz DDS Function Generator with sweep and 120MHz counter DDS frequency generation 0.001Hz to 10MHz frequency range using DDS The TG1006 has been developed from the highly successful TG300 and 6 digits or 1mHz setting resolution TG550 series of analog function generators. However, the TG1006 uses DDS frequency generation to provide greater accuracy and stability, and to cover a 1ppm stability and <10 ppm absolute accuracy for one year wider frequency range. Sine, square and triangle waveforms DDS (direct digital synthesis) is a technique for generating waveforms digitally Low distortion, high spectral purity sine waves using a phase accumulator, a look-up table and a DAC. The accuracy and stability of the resulting waveforms is related to that of the crystal master Simultaneous display of frequency and amplitude/offset clock. External seven digit 120MHz frequency counter When correctly engineered, the DDS generator offers not only exceptional Internal full range phase continuous sweep, linear or log accuracy and stability but also high spectral purity, low phase noise and excellent frequency agility. Unique manual sweep mode for quasi-analog control Modulations modes of AM, FSK and frequency list Wide frequency and amplitude range 2mV to 20V pk-pk output from 50W or 600W The TG1006 can generate waveforms between 0.001Hz and 10MHz with a resolution of six digits and a one year accuracy better than 10ppm. Storage for up to ten frequencies in non-volatile memory Amplitude is variable between 2mV and 20V pk-pk from a source impedance of 50W or 600W. Frequency list and stepping Numeric or spin-wheel frequency control The generator has non-volatile storage for up to 10 frequency settings. Frequencies can be entered directly from the numeric keypad in units of Hz, These can be used as random storage for commonly used frequency values, kHz or MHz. or can be stepped through in sequence as may be required in a repetitive test Alternatively any digit can be incremented or decremented using the spin routine. wheel. AM Quasi-analog frequency control Amplitude modulation from 0 to 100% is provided using either an internal One advantage that analog function generators have over digital ones is that 400Hz source or an external source (DC to 20kHz). All waveforms can be the frequency can be changed using an analog control. This provides intuitive modulated. operation which is ideal for the setting up of frequency dependent parameters External frequency counter such as checking filter characteristics. In external counter mode the full width of the display is used to provide up to The TG1006 provides a similar capability via its manual sweep mode. A seven digits of resolution. dedicated analog control sweeps the frequency over any defined span in a similar way to an analog generator, but with the added advantage that the The frequency range is from 3Hz up to more than 120MHz, and the input span can be precisely controlled and can extend to almost the full range of the sensitivity is better than 50mV rms. generator. A reciprocal counting measurement system is used which ensures high resolution regardless of input frequency. Wide range sweep Suitable for bench or rack All waveforms can be swept over almost the full frequency range (0.1Hz The generator is housed in a 2U high case with built-in tilt stand. A rack to 10MHz) at a rate variable between 100 milliseconds and more than 15 mounting kit is available. minutes. The sweep is fully phase continuous and can be linear or logarithmic, single or continuous. FSK Frequency Shift Keying provides phase coherent switching between two selected frequencies at a rate defined by the trigger source which can be the front panel key or internal timer (10kHz maximum).
