Arbitrary Waveform Generators
have up to four channels.
The TGA1240 Series, new from TTi (Thurlby Thandar Instruments),
is a range of arbitrary waveform generators comprising one-,
two- and four-channel instruments.
The multi-channel versions are capable of generating two or
four waveforms, which can be either fully independent or linked
using simple or complex relationships. They can provide full
inter-channel triggering, summing and phase control. Any number
of channels can be phase-locked with user-defined phase angles.
This technique can be used to generate multi-phase waveforms
or locked waveforms of different frequencies. Two generators
can be locked together where more than four channels are required.
The TGA1240 series uses a true variable-clock architecture with
a maximum clock rate of 40 MHz. It can also operate in direct
digital synthesis (DDS) mode. It can generate signals within
the frequency range 0.001 Hz to 16 MHz.
Arbitrary waveforms may be defined with 12-bit vertical resolution
and from 4 to 65536 horizontal points. In addition, a number of
standard waveforms are available, including sine, square, triangle,
ramp and pulse. Waveforms may be replayed at a user specified
waveform frequency or period, or the sample rate may be defined.
The total amount of non-volatile waveform store is 256K words.
Up to 100 waveforms may be stored, with the length and name
specified by the user.
All waveforms can be swept over their full frequency range at a
variable rate. Amplitude modulation and signal summing are
available for all waveforms, and are controlled from the previous
channel or from an external generator.
Extensive waveform editing features between defined start and
end points are incorporated, including waveform insert, point edit,
line draw, amplitude adjust and invert.
The TGA1240 series uses an 80-character backlit LCD display
with soft keys. All parameters can be entered directly from the
numeric keypad, or can be incremented and decremented using
the rotary control. RS-232 and GPIB interfaces are fitted as standard,
and can be used for remote control of all of the instrument functions
or for the downloading of arbitrary waveforms.
Prices for the TGA1240 Series range from £1095 up to £2995 (plus VAT).
