1.1 Generator output
The generator consists of a DAC whose input is derived
from a table held in RAM. The appropriate pattern is
loaded into the RAM (sinewave, sawtooth etc.) by the DSP,
and then the RAM address is stepped at a rate given by
the selected frequency. The output of the DAC is
attenuated, has any offset added, is filtered and is
buffered by a high speed, high current buffer.
The DAC is clocked at 11.52 MHz.
The DAC resolution is 14 bit.
The RAM depth is 16k words x 16 bit.
The maximum output level is 10V peak.
The maximum output current is 200mA peak.
The 0V of the output is earthed.
There is a 50 output impedance.
