Description Precision 5MHz Function Generator
                                    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
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.
