Modulating the Laser Current Source
88 LDX-3232
CHAPTER 5
To disable the output, press the OUTPUT push button again. When the LDX-3232
current output is off, an internal short is placed across the output. This short will
prevent the modulation signal from reaching the LED in our example experiment.
Thus, it is safe to disconnect the test device (LED) when the LDX-3232's output is
off, regardless of the presence of the modulation signal.
