The TG4001, new from TTi, is a low cost DDS function generator with
arbitrary waveform capability that can generate high purity sine waves
up to 40MHz and square waves up to 50MHz, double the frequency of other
functions generators within a similar price bracket.
In addition to sine and square waves, it can generate cosine, haversine,
havercosine, pulse, triangle, ramp and sine(x)/x waveforms. Setting
resolution is 10 digits or 1mHz.
The TG4001 can generate not just pulses but complex pulse trains. A
pattern of up to 10 pulses can be quickly defined with each pulse having
its own amplitude, width and delay. The whole pulse train pattern can
then be replayed at a user defined repetition rate.
As an arbitrary generator, it can produce waveforms of up to 65,536
(64K) words at sample rates of up to 100MS/s. Waveform Manager Plus
software for Windows is supplied for creation and editing of waveforms
on a PC. Waveforms are downloaded to the generator using RS232 or USB
interfaces.
A full voltage output signal of 5mV to 20V pk-pk EMF from 50 Ohms is
available over the full frequency range of the generator. Amplitude
flatness for sinusoids is +/-0.2dB to 1MHz and +/-0.4dB to 40MHz. Pulse
rise and fall times are less than 8ns.
Modulation modes include wide-range phase-continuous sweep, AM, tone
switching, and signal summing. A built-in trigger generator provides
gated & triggered burst modes. All waveforms can be swept over their
full frequency range at a variable rate.
The TG4001 includes both RS232 and USB interfaces as standard. These
give full control of every instrument function as well as providing
arbitrary waveform download capability. A GPIB (IEEE-488) interface is
available as an option.
The generator is housed in a half rack 3U case suitable for bench top or
system use. A rack mount kit is available.
The TG4001 costs £995 in the UK and 1495 Euros in Continental Europe
The approximate International price is $1850.
