Introduction

The TG550 is a precision 5MHz function generator with waveforms of sine, triangle, ramp. pulse
and DC from a variable amplitude 50Ω or 600Ω output. A TTL/CMOS auxiliary output is also
provided.
The frequency range is 0·005Hz to 5MHz selected by a seven decade range multiplier and
calibrated vernier. Both the frequency vernier and the sweep input can give 1000:1 frequency
change within a selected range. Frequency can be locked to a crystal reference to give superior
frequency stability. A 10:1 symmetry range permits ramp and pulse waveforms to be produced.
The generator output level is 20Vpk-pk maximum from a 50/600Ω source. The level is set via a
switched attenuator plus vernier with a total range of >80dB. DC offset is vernier adjustable over
a ±10V range with centre detent for 0V. Waveform quality is good at all frequencies and signal
levels.
The TG550 also has internal LIN/LOG sweep with sweep output. Amplitude modulation of up to
100% is possible using the internal 400Hz oscillator or an external source.
The large liquid crystal display shows frequency and amplitude simultaneously. Good resolution
and a fast display update rate are maintained at all frequencies. The display can also be used as
an external 20MHz frequency meter with up to 7-digit resolution.
Additional display annunciators indicate generator status when sweep, AM, etc. are in use.
