Power-on Conditions
At power−on, the 8033 initializes the instrument parameters to be the same as when the instrument
was last powered−down. The laser output is always off at power−up.

More Information

Please read Chapter 2, Local Operation, to become familiar with all of the features of the 8033.
GPIB operation is discussed in Chapter 3, Remote Operation and Chapter 4, Command Reference.
Calibration is described in Chapter 5, Maintenance.

Use the DISPLAY switch to toggle the display units between linear scale
(mW), log scale relative to 1 mW (dBm) and log scale relative to a user
defined reference (dB).
The ADJUST KNOB is used to set various parameters such as the output
power and GPIB address. Clockwise rotation of the knob increases the
parameter value.
Use the CW switch to force the output to a continuous wave (CW) mode.
The first execution of the INT MODULATION switch will change the
modulation to the last used frequency. Subsequent executions of the INT
MODULATION switch will toggle between the three available internal
modulation frequencies.
Use the knob to set any desired reference power. Then press the SET
REFERENCE switch to establish that power as the reference for the dB
scale. When the SET REFERENCE switch is pressed the display
automatically changes to the dB scale.
Connect a fiber optic patch cord to the FC connector on the front panel of
the 8033. Press the (OUTPUT) ON switch to turn on the source. A two
second safety delay is indicated by the flashing (OUTPUT) ON LED
indicator. After the delay, the source enables and the indicator is solidly
illuminated. To turn the source off press the (OUTPUT) ON switch again.
The (OUTPUT) ON LED indicator will extinguish.
To view the GPIB address press the LOCAL/ADR switch when in the local
mode. In remote, press LOCAL/ADR to return the device to local control.
Instructions for setting the GPIB address are found in Setting the GPIB
Address on page 20.
The TTL OUT connector on the rear panel is the electrical equivalent of the
front panel optical output. It can be used as a synchronization signal.
Errors are indicated on the display in the form Exxx where xxx is a three
digit number representing the error. See Error Messages on page 83.
