19. Alternate Timeslot Power Settling Time
(Option UNA only)
This test measures the time required for a waveform envelope to settle within the
tolerance of its final amplitude after a sharp amplitude transition provided by the
Alternate Timeslot Power feature (Option UNA). Settling time is the result of heating and
cooling effects in the step attenuator and ALC loop. The rise and fall response times of the
ALC loop and each attenuator segment is characterized and combined to construct the
settling curve for any arbitrary transition.
Recommended Equipment
• HP/Agilent 8563E Option 007 Spectrum Analyzer
• HP/Agilent 8491A/B Option 010 Attenuator (10 dB)
