Frequency locking for
exceptional stability
The TG550 includes a digital frequency
locking system that gives it a level of
frequency stability that cannot be matched
by conventional analogue function gen-
erators.
Once the frequency has been set, pressing
the Lock key engages a measure-and-
correct circuit which compensates for the
small thermal and mechanical drifts that in-
evitably occur in an analogue generator.
The frequency is compared to a crystal con-
trolled reference and is maintained to within
0.01% of the set frequency.
TG550 5MHz function generator with sweep
A state-of-the-art
instrument
The function generator is one of the most
versatile pieces of test & measurement in-
strumentation available.
It can generate a variety of precision
waveshapes over a range of frequencies
from mHz to MHz. It can provide a wide
range of controlled amplitudes from a
low-impedance source, and maintain con-
stant amplitude as the frequency is varied.
Voltage control of frequency enables a
source of swept frequency to be gener-
ated for frequency response testing. AM
and FM modulation can also be added.
The TG550 represent the state-of-the-art
in 5MHz analogue function generators.
digital frequency locking for exceptional accuracy and stability
Exceptional waveform quality
The TG550 provides very high waveform
quality under all conditions.
That means low sinewave distortion, low
aberration triangle waves and fast-edged
square waves with low overshoot.
Unlike many competitive products good
waveform quality is maintained through-
out the frequency range and at low output
levels.
Variable symmetry for pulse
and ramp waveforms
The TG550 series provides bi-directional
variable symmetry from 1:9 to 9:1. Unlike
some products, frequency is independent
of symmetry setting.

1000:1 frequency change by vernier or sweep voltage

or 600
Wide range level control
The TG550 series provides a main output
with a maximum emf of 20V pk-pk from a
50 or 600 source.
An amplitude vernier with a range of 20dB
is combined with two switched attenua-
tors of -20dB and -40dB to provide levels
down to 2mV pk-pk unterminated.
Variable DC offset of ±10V is available via
a center detent control. An auxiliary output
provides a fixed 0V to +5V level suitable
for driving both TTL and CMOS loads.
Wide sweep range
Each range can be swept by at least
1000:1 either manually, via the external in-
put, or using the built-in sweep generator.
