Return loss module specifications with internal source
(When used with external sources the specifications of Agilent 81610A return loss module apply)
All modules require angled contact (8°) at input and output connectors
1. At 25 °C constant temperature, coherence control on,
warm-up time after laser turn on > 5 min
2. Averaging time 1 s
• calibration prior to measurement
• constant temperature
• coherence control on
• warm-up time after laser turn on > 5 min
• length of measurement patch cord ≤ 2 m
• angled connector in optimal optical condition
• Reference cable 81610CC used for total uncertainty
3. Use defaults settings (no user calibration necessary):
• length of measurement patch cord ≤ 2 m
• return loss of connectors ≥ 70 dB
4. For measurements performed immediately after calibration
5. Warm-up time 60 min, if previously not stored at the same temperature
