The TG2000, new from TTi, is a 20MHz function generator using direct
digital synthesis (DDS) yet costing less than £500.
Direct digital synthesis delivers low distortion sine waves with
improved spectral purity in comparison analogue function generators.
Frequency stability and phase noise are excellent and absolute frequency
accuracy is better than 10 ppm.
The TG2000 is a fully digitally controlled generator in which all
functions including wave shape, frequency, amplitude, offset, and
modulation can be controlled from the digital interface (USB) or by
recall from the internal set-up memories. This makes it particularly
suitable from automated or repetitive test applications.
The generator incorporates fully phase-continuous sweep, linear or
logarithmic, with sweep times variable between 50ms and 1000s. The sweep
trigger source can be internal or external (including USB command) and a
sweep marker is provided. Other modulation modes include AM, Gated, FSK
and Tone-switch using a table of up to 16 frequencies.
The TG2000 can generate frequencies between 0.001Hz and 20MHz to six
digits of resolution at amplitudes between 5mV and 20V pk-pk EMF. Source
impedance is switchable between 50 Ohms and 600 Ohms.
A USB interface is incorporated which can provide full remote control of
the instrument. Nine internal non-volatile set-up memories are also
The TG2000 is housed in a 2U high casing which, although primarily
intended for bench to use, can also be rack mounted.
The TG2000 costs £499 in the UK and 749 Euros in Continental Europe
The approximate International price is $900.
