54. Recall the HP 37717C DEFAULT SETTINGS as shown on 3-2.
55. Verify that the Optical Module LASER ON led is NOT lit indicating that the laser
is disabled before continuing.
56. Reconnect the HP 37717C 1550 nm Optical Out Port to the HP 8153A Power
Meter via the HP 8157A Optical Attenuator.
57. Press
on the HP 37717C and select SIGNAL [STM-4 OPT]
[1550 nm].
58. Adjust the Optical Attenuator level to obtain a reading of -28dBm
±
1dB on the
Power Meter.
59. Recall the HP 37717C DEFAULT SETTINGS as shown on 3-2.
60. Verify that the Optical Module LASER ON led is NOT lit indicating that the laser
is disabled before continuing.
61. Disconnect the optical cable from the Power Meter and connect to the HP 37717C
Optical IN Port.
62. Press
on the HP 37717C and select SIGNAL [STM-4 OPT]
[1550 nm].
63. Press
then
to start the
measurement.
64. After 5 minutes, check that NO TROUBLE is displayed on the HP 37717C
display.
Press
to stop the measurement.
65. Repeat steps 54 through 64, selecting SIGNAL [STM-1 OPT] [1550 nm] in steps
57 and 62 and -34dBm
±
1dB in step 58.
66. Repeat steps 54 through 64, selecting SIGNAL [STM-0 OPT] [1550 nm] in steps
57 and 62 and -34dBm
±
1dB in step 58.
67. Recall the HP 37717C DEFAULT SETTINGS as shown on 3-2.
68. Verify that the Optical Module LASER ON led is NOT lit indicating that the laser
is disabled before continuing.
69. Disconnect the optical cable from the HP 37717C STM1/4 Optical IN Port and
connect to the HP 83442A Optical/Electrical Converter input.
70. Connect the output from the Optical /Electrical Converter to the Oscilloscope
using the SMA/BNC adaptor and 50
Ω
BNC cable.
