This Agilent 83430A OPT 130 Lightwave Transmitter was tested using an external optical power meter and single-mode fiber-optic cable. The measurements below are actual readings obtained from this unit.
| TEST | MEASURED OUTPUT |
|---|---|
| Digital Preset | -9.84 dBm |
| Analog Maximum Bias | -0.18 dBm |
| Analog Minimum Bias | -2.24 dBm |
| Digital Variable Bias Maximum | -4.84 dBm |
✔ Power-On Test
Unit powers on successfully.
✔ Optical Laser Output
Measured optical output through the transmitter's OPTICAL OUT connector using a fiber-optic power meter.
✔ Laser Power On/Off Response
Optical output dropped to the meter's low indication (approximately -50 dBm) when the transmitter was switched off.
✔ Digital DC-Coupled Mode
Selected and verified optical output in digital mode. Preset output measured -9.84 dBm (0.103 mW / 103 µW), close to the manufacturer's -10 dBm reference level.
✔ Digital Variable Bias Control
Optical output increased as the control was adjusted. Intermediate measurement: -6.17 dBm (0.241 mW). Maximum measurement: -4.84 dBm (0.328 mW).
✔ Preset / Variable Bias Switching
Switching back to PRESET restored the original -9.84 dBm reading.
✔ Analog AC-Coupled Output Test
Analog mode was selected and optical output measured. Maximum bias: -0.18 dBm (0.963 mW). Minimum bias: -2.24 dBm (0.597 mW). Both readings were within the stated analog bias endpoint limits.
✔ Front-Panel Controls
SELECT, BIAS ADJUST, and PRESET/VARIABLE controls responded during testing.
