새로운 기술에 대응하여 설계된 Generators

The expansion of electronics within every engineering discipline is requiring today’s engineers to

generate ever more diverse and complex signals.

The TGA1240 series of universal wave-form generators has been designed to meet that challenge.

Powerful arbitrary, function and pulse gen-erator capabilities are combined with com-prehensive

modulation modes and up to four independent channels.

단독 또는 다중 채널

The TGA1240 series comprises three models :

TGA1244 - Four channel waveform gen-erator in 3U rack size case.

TGA1242 - Two channel waveform gener-ator in 3U rack size case.

TGA1241 - Single channel waveform gen-erator in 3U half rack size case.

Each channel can be operated fully inde-pendently, or multiple channels can be linked using simple or

complex relation-ships.

통합 기능 제공

Each channel can operate as a full DDS function generator. High quality sine, co-sine, haversine,

havercosine and square waves are available between 1mHz and 16MHz. Setting resolution is 7 digits or

1mHz. Triangle, ramp and sine(x)/x waveforms are available from 0.1mHz up to 100kHz.

다양한 펄스 생성 지원

Each channel 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
am-plitude, width and delay. The whole pulse train pattern can then be replayed at
a user defined repetition rate.
Where variable rise time pulses are required, the full arbitrary function can be used.

가격 대비 다양한 기능 지원

The TGA1240 series are highly sophisti-cated 12-bit arbitrary generators capable of recreating virtually any

waveform. True variable clock architecture is used with clock speeds between 0.1Hz and 40MHz.

This architecture avoids the clock jitter associated with DDS arbitrary generators and permits waveform

linking, loop-ing and sequencing.

Waveforms may be defined with up to 4096 vertical points and from 4 to 65,536 horizontal points.

Arbitrary waveforms may be replayed at a specified waveform frequency, period or sample rate.

Up to 100 user-defined waveforms can be stored within the instrument’s 256K of non-volatile memory.

▣ Linked-sequence operation

Up to sixteen arbitrary waveforms may be linked in a sequence.
Each waveform can have a loop count of up to 32,768 and the whole sequence
can be run continuously or repeated more than a million times.
For multi-channel models, waveforms on different channels can be ‘daisy chained’
and looped. By summing the channel outputs, up to 64 segments can be used to		Simple waveform
create highly complex waveforms.		sequence

▣ Easy waveform editing

Waveform creation and editing features are incorporated within the instrument. Theseinclude waveform insert,

point edit, line draw, amplitude adjust and invert.

Start and End points and data values can be defined using the keypad or the rotary control.

A wide range of standard waveforms is available for insertion within an arbitrary waveform.

These include sine, triangle, ramp and square. Sections of existing arbitrary waveforms can also be inserted.

For more sophisticated waveform editing, Windows based software is provided (see the next page for more

detail). Waveforms created on a PC can be downloaded to the instrument via the RS232 or GPIB interfaces.

다중 채널 기능 (TGA 1242 and 1244)

▣ 다중 채널 phase locking

Any number of channels can be phase locked with offsets defined to a resolution of
0.1˚(or 360˚/waveform points for arbitrary waveforms).
For applications requiring more than four chan-nels,multiple generators can
be phase locked. N.B. The TGA1241 also has the facility for phase locking to
another generator.

▣ 다중 채널 합성 기능 제공

Waveform Summing sums the waveform from any channel into the next channel.
Alternatively any number of chan-nels can be summed with an external signal.
This permits complex modu-lations to be created such as noise superimposition.
		Arbitrary waveform
		summed with noise

▣ 내부 채널 트리거링 및 변조

Because any channel can be triggered by the previous or next channel,

waveforms on different channels can be ‘daisy chained’ and looped.

By summing the channel out-puts, up to 64 segments can be used (32 segments for TGA1242).

A channel can be used to AM modulate or SCM modulate another channel.

▣ 디지탈 파형 변조

Inter-channel modulation and summing allows the simulation of various telecom
digital modulation systems.
IQ Modulation signals (Quadrature Amplitude Modulation)

광범위의 sweep 기능

All waveforms can be swept over their full frequency range at a rate variable between 30 milliseconds and

15 minutes. Sweep can be linear or logarithmic, single or continuous. Single sweeps can be trig-gered

from the front panel, the trigger in-put, or the digital interfaces.

Multiple channels can be swept simulta-neously.

증폭 변조

Amplitude Modulation and Suppressed Carrier Modulation are available for all
waveforms. Any channel can be used to modulate an-other channel.
Alternatively all channels can be modulated simultaneously via the modula-tion input.
		Amplitude modulation

Built-in trigger generator

All waveforms are available as a triggered burst whereby each trigger edge will pro-duce one burst of the

carrier. Start and stop phase is fully variable. Both Triggered and Gated modes can be operated from the

internal trigger genera-tor, from an adjacent channel, an external source or a key press or remote command.

The trigger generator signal is available as a separate output if required.

Tone switching

The TGA1240 series can provide triggered switching between up to 16 frequencies of
standard or arbitrary waveforms. Tone switching modes can be gated, trig-gered
or FSK using any trigger source. By summing two channels together it is
possible to gen-erate precise DTMF test signals.		Simple tone switching

RS-232와 GPIB를 통한 프로그래밍 기능

The TGA1240 series incorporates both an RS-232 interface and a GPIB (IEEE-488) interface as standard.

These can be used for loading arbitrary waveforms and for remote control of all in-strument functions.

		Sinewave with defined harmonic distortion containing odd harmonics only.
		Generated on a PC using the equation editor to add 10% of 3rd harmonic, 5% of 5th
		harmonic, and 2.5% of 7th harmonic.

빠르고 손쉬운 조작법

All of the main information is clearly dis-played on a backlit 80 character LCD.

Eight “soft” keys provide fast data editing. On the 1242 and 1244, a Copy Channel key enables similar setups

to be created across multiple channels with ease.

All parameters can be entered directly from the numeric keypad. Alternatively most parameters can be

incremented or decremented using the rotary control.

보다 높은 전압 발생 가능

For applications requiring more than 20V pk-pk emf, an external wideband amplifier is available.

The WA301 can provide up to 30V pk-pk from 50W.

Simulated cardiac waveform and control pulses.

윈도우에 기반한 파형 조작

Each generator is supplied complete with sophisticated
Windows based software for the creation, editing and
management of waveforms.
This powerful software can be used to create arbitrary
waveforms from scratch using drawing tools, equations or
both together.
Real-world waveforms imported from DSOs or other sources can
be modified and combined with other waveforms using editing
functions.

A library of ‘standard’ waveforms is included which can be used as ‘elements’ when creating or modifying

waveforms. A powerful Equation Editor provides an array of mathematical functions including logarithmic

and geometric operands. Waveform creation and editing can make use of drawing tools in combination with

equations, insertion and manipulation. Multiple waveforms can be further com-bined using mathematical

operators to create new waveforms.

▣ Import from DSOs and other instruments

The Windows software incorporates direct support for uploading waveforms from Tektronix digital

oscilloscopes. A driver for LabWindows CVI from National Instruments is available which enables imports

from other equipment to be achieved within the LabWindows environment.
