Function generator has a longer memory
The TGA12101 arbitrary/function generator has been redesigned to incorporate one million words of high-speed waveform memory giving it the longest memory of any instrument in its class.
Compact bench power supply provides 175W
The EX355, new from TTi (Thurlby Thandar Instruments), is a single-output laboratory DC power supply providing an output from 0 to 35V at 0 to 5A.
The TGA12101 can operate as a DDS (direct digital synthesis) function generator producing high-quality sine, cosine, haversine and havercosine waveforms at frequencies from 1mHz to 40MHz, with square waves available up to 50MHz.
Triangle, ramp and sine(x)/x waveforms are also available.
Setting resolution is 10 digits or 1mHz.

Programmable synthesised 1GHz RF generator
The TGR1040GP from TTi (Thurlby Thandar Instruments) is a programmable synthesised RF signal generator with a frequency range up to 1GHz.
The instrument can also operate as a true variable-clock arbitrary generator.
Variable-clock architecture provides much greater capabilities than the DDS arbitrary system used on many generators.
Arbitrary waveforms may be defined with 12bit vertical resolution and from 8 to 262,144 (256K) horizontal points.
The waveform replay clock is variable between 0.1Hz and 100MHz, or can be driven from an external source.
Unlimited nonvolatile waveform storage is provided using removable CompactFlash memory cards.
Waveforms may be strung together to form a sequence of up to 1024 steps.
Each waveform may have a user-defined repeat count from 1 to 32,768.
This allows highly complex waveforms to be created.
The TGA12101 can generate not just pulses but complex pulsetrains.
A pattern of up to 10 pulses can be quickly defined, with each pulse having its own amplitude, width and delay.
The whole pulsetrain pattern can then be replayed at a user-defined repetition rate.
Where variable rise-time pulses are required, the arbitrary facility can be used.
Modulation modes include wide-range phase-continuous sweep, AM, tone switching, and signal summing.
A built-in trigger generator provides gated and triggered burst modes.
All waveforms can be swept over their full frequency range at a variable rate.
Amplitude modulation and signal summing is available for all waveforms, and is controlled from the other channel or from an external generator.
Comprehensive waveform creation and editing features are available using the Waveform Manager Plus arbitrary waveform software supplied.
This is a powerful Windows-based design tool that enables the user to create waveforms from mathematical expressions, from combinations of other waveforms, freehand drawing, or using a combination of all three techniques.
Clipboard import and export provides an easy way of using waveforms captured from digital storage oscilloscopes or waveform digitisers.
The TGA12101 has an 80-character backlit LCD with soft keys.
All parameters can be entered directly from the numeric keypad or can be incremented and decremented using the rotary control.
The instrument is cased in a 3U half-rack-width casing with integrated tilt feet.
Serial and GPIB interfaces are fitted as standard and can be used for remote control of all of the instrument functions and for the downloading of arbitrary waveforms.
Waveforms can also be transferred between the instrument and a PC using the CompactFlash memory card, and a USB interfaced card reader is provided for this purpose.
The TGA12101 costs GBP 1595 (plus VAT) in the UK.
