6.10 Analog
Output
The SSP has two LEDs connected to the analog output channel. The yellow LED indicates positive
analog output voltages, while the green LED indicates negative analog output voltages.
The analog output can be set by the command
VO=level
where level is in millivolts in the range –10000 to 10000mV.
For example the command
VO=5000
will turn the yellow LED on to approximately half intensity, while
VO=-5000
will turn the green LED on to approximately half intensity.
The DeLogger program Prog17.dl8 puts a ramp volt output on the AO channel. You will observe the
intensity of the two LEDs changing.
