A value-for-money 10MHz or 20MHz function generator

with the precision of Direct Digital Synthesis

0.001Hz to 10MHz or 20MHz frequency range, 6 digits or 1mHz setting resolution.

1ppm stability and better than 10 ppm absolute accuracy for one year.

Sine, square, triangle, positive pulse and negative pulse waveforms.

Low distortion, high spectral purity sine waves.

Internal sweep, linear or logarithmic, full range phase continuous, adjustable marker.

Modulations modes of gated, AM, FSK and tone switching; built-in trigger generator.

or 600

; plus multi function auxiliary output.

Storage for up to nine complete instrument set-ups in non-volatile memory.

Fully programmable via RS-232 or USB interfaces (TG2000 only).

Ease of use

The TG1000 and TG2000 are particularly

easy to use. All of the main information is

clearly displayed on a backlit LCD with 4

rows of 20 characters. Sub menus are

used for the modulation modes and other

complex functions.

All parameters can be entered directly from

the numeric keypad. Alternatively most pa-

rameters can be incremented or decre-

mented using the rotary encoder for

quasi-analogue control.

Frequency or period entry

The generator frequency can be set in

terms of either frequency or period.

Numeric entry is floating point using what-

ever units the operator prefers.

Flexible amplitude entry

Amplitudes can be entered in terms of peak

to peak voltage, RMS voltage or dBm.

The output impedance can be set to 50Wor

600W, and the amplitude can be set in

terms of either the voltage into the correct

termination, or the source EMF (for a high

impedance load).

Quick recall of settings

Both generators provide nine memories for

storing settings.

Because all parameters are controlled

electronically, the memories store the full

set-up of the instrument and automated

test sequences are easy to set up.

In addition to the nine user memories, the

current state of the instrument is saved at

switch off. The user can choose to have

this state restored at switch on, or choose a

pre-defined default set-up.

Synchronisation

The auxiliary output socket can provide any

one of three different Sync. signals.

Waveform Sync is a 50% duty cycle square

wave at the frequency of the main output.

Sweep Sync. outputs a pulse at the start of

each sweep and can also output a pulse at a

user defined marker frequency.

Trigger Out provides a replica of the trigger

signal which can be from the trigger input

socket, the internal trigger/gate generator,

the manual trigger key, or the bus interface.

Modulation modes

Sweep

All waveforms can be swept over their full

frequency range (0.2Hz minimum) at a rate

variable between 50 milliseconds and

more than 15 minutes. The sweep is fully

phase continuous.

Sweep can be linear or logarithmic, single

or continuous. Single sweeps can be trig-

gered from the front panel, the trigger input,

or the digital interfaces.

A sweep marker is provided that is adjust-

able whilst sweep is running. The markers

can provide a visual indication of frequency

points on a ‘scope or chart recorder.

Gated

The Gated mode sets the output signal on

or off depending on the gating signal state.

The gating source can be the front panel

key, internal trigger generator, trigger input

socket, or bus interface signal.

External Amplitude Modulation of up to

100% is available for all waveforms via the

VCA input.

FSK

Frequency Shift Keying provides phase co-

herent switching between two selected fre-

quencies at a rate defined by the source.

The switching source can be the front panel

key, internal trigger generator, trigger input

socket, or bus interface signal.

Tone Switching

The generator can be set to switch be-

tween a number of different frequencies in

response to a trigger signal.

Up to 16 frequencies can be defined.

and full digital control via RS-232 or USB (TG2000 only)

A new price point

The TG1000/2000 breaks new ground by offering a high quality

DDS function generator at a significantly lower price.

DDS (direct digital synthesis) is a technique for generating

waveforms digitally using a phase accumulator, a look-up table

and a DAC. The accuracy and stability of the resulting wave-

forms is related to that of the crystal master clock.

When correctly engineered, the DDS generator offers not only

exceptional accuracy and stability but also high spectral purity,

low phase noise and excellent frequency agility.

Total digital control

Unlike some other generators which only provide digital control

of frequency, every function is digitally controlled enabling

complete instrument set-ups to be stored, or full remote control

to be implemented (TG2000 only).

Wide frequency and amplitude range

The TG2000 can generate waveforms between 0.001Hz and

20MHz with a resolution of six digits and a one year accuracy

better than 10ppm. The TG1000 has a 10MHz limit.

Amplitude is variable between 5mV and 20V pk-pk from a source

impedance of 50Wor 600W.

Unlike many generators, the waveform quality remains excellent

over the full amplitude range.

RS-232 and USB interfaces

The TG2000 also includes both an RS-232 interface and USB

interface.

These interfaces can be used for remote control of all of the in-

strument functions and for remotely storing instrument

set-ups.

Amplitude modulation using an external sine

wave modulation source.

See the difference !

Ultimately what matters in a function gener-

ator is the quality of the output signal.

The TG1000/2000 maintains the TTi

reputation for high signal quality at all

frequencies and all levels.

The waveform capture opposite shows just

how much difference that can make !
