Introduction for light source module
1. Open and close light source.
If it is the first time to enter into the status of light source
output
state,
it
dose
not
output
signal.
And
“
1310nm
”
,
”
1550nm
“
or
“
Closing the light source
”
can be
chosen circularly by pressing
“λ”
.
2. The modulation output of light source.
When any wavelength is chosen, press
“▲”
or
“▼”
to
realize the modulation selection of CW, 270Hz, 330Hz,
1KHz, 2Khz, --AU auto wavelength identification.
3. Display the working status information of stable light
source
The
on the upper left of the LCD is blinking all the
time when there is some working light source. And it is
forbidden to look at the output end of laser source or the
connector of the optical fiber when the light source is under
the power on status. The LCD displays the corresponding
wavelength and modulation status when the tester is under
the module of stable light source. When it is back to the
module of optical power, the LCD displays the information of
optical power, as well as the corresponding working light
source, it will indicate 1310nm or 1550nm on the upper side
of
“
Main display 1
“
or
“
Main display 3
”
. And it also shows the
modulation frequency of the light source on the upper side
of LCD. When the light source is under the modulation of
“
Auto
”
, its corresponding working light source (1310nm or
1550nm
）
will be blinking all the time.
