This instrument is a 20MHz function generator with waveforms of sine, square, triangle, ramp, pulse and
DC from a variable amplitude 50Ω output. A TTL output is also provided.
The frequency range is 0.2Hz to 20MHz selected by an eight decade range multiplier and calibrated
vernier. The sweep input can be used to give a >20:1 frequency change within a selected range.
The generator output level is 20Vpk-pk maximum from a 50Ω source. The level is set via switched
attenuators plus vernier with a total range of 66dB. DC offset is vernier adjustable over a ±10V range with
0V defined by a centre detent.
A switchable symmetry control with a 6:1 range permits ramp and pulse waveforms to be produced.
