measurement.
60. After 5 minutes, check that NO TROUBLE is displayed on the HP 37717C
display.
Press to stop the measurement.
61. Repeat steps 50 through 60, selecting SIGNAL [STM-1 OPT] [1550 nm] in steps
53 and 58 and -34dBm in step 54.
62. Recall the HP 37717C DEFAULT SETTINGS as shown on Page 3-2.
63. Verify that the Optical Module LASER ON led is NOT lit indicating that the laser
is disabled before continuing.
64. Disconnect the optical cable from the HP 37717C STM1/4 Optical IN Port and
connect to the HP 83442A Optical/Electrical Converter input.
65. Connect the output from the Optical /Electrical Converter to the Oscilloscope
using the SMA/BNC adaptor and 50Ω BNC cable.
66. Set the Dual Power Supply to +12V and -12V, then connect to the HP 83442A
O/E Converter and switch on.
CAUTION Take care to connect the supply correctly as incorrect voltage or polarity could result
in damage to the HP 83442A. Refer to HP 83442A Operating Instructions, HP p/n
