Regards, Aseel Data from occultation 15972i collected at DSS 15 (start time 2002/277- 13:05:00) have a +/-0.2 dB 7 second modulation on the free space carrier amplitude for most of the time before ingress. Data collected from DSS 15, occultation 15948i (start time 2002/275-14:00:00) had +/-1 dB sinusoidal modulation on the free-space carrier amplitude with period of ~10 seconds. The modulation was present before telemetry turned off but not noticeable in the noise level after ingress. amplitude over the course of the measurement, with +/-0.3 dB random fluctuations. Data collected from DSS 15 occultation 15924e (start time 2002/273- 13:42:00) had +/-0.7 dB sinusoidal modulation of the carrier amplitude with period of about 10 seconds. There was no modulation of the noise level either before or after the carrier appeared. Data collected from DSS 15 occultation 15924i (start time 2002/273- 14:56:00) may have very small-amplitude modulation of the carrier level (amplitude ~0.1 dB) with a similar ~10 s period. The first measurement collected at DSS 15 (occultation 15936i, start time 2002/274-14:28:00) had +/-0.2 dB modulation on the free-space carrier amplitude with period of about 5 seconds. The first measurement collected on day 272 at DSS 15 (occultaion 15911i, start time 2002/272-13:26:00) had max SNR levels about 1 dB lower than expected. In addition there was a +/-0.5 dB sinusoidal modulation on the free-space carrier amplitude, with period of about 10 seconds. There was no modulation on the carrier before telemetry was turned off or on the noise level. The last measurement collected on day 272 at DSS 15 (occultation 15915i, start time 2002/272-21:16:00) had a +0.5 dB ramp in the free-space carrier -------------------------------------------------------------------------- From rsimpson@magellan.stanford.edu Wed Oct 9 14:54:06 2002 Received: (from rsimpson@localhost) by magellan.stanford.edu (8.11.6/8.11.6) id g99Ls5e07915; Wed, 9 Oct 2002 14:54:05 -0700 (PDT) Date: Wed, 9 Oct 2002 14:54:05 -0700 (PDT) From: Dick Simpson 723-3525 Message-Id: <200210092154.g99Ls5e07915@magellan.stanford.edu> To: aseel@godzilla.jpl.nasa.gov, joe@nova.stanford.edu, kusza@magellan.stanford.edu, rsimpson@magellan.stanford.edu Subject: Re: Modulation at SPC-10 Cc: SAbbate@jftl.jpl.nasa.gov Content-Length: 1461 Status: R >15972i 2002/277-13:05:00 >15948i 2002/275-14:00:00 >15924e 2002/273-13:42:00 >15924i 2002/273-14:56:00 >15936i 2002/274-14:28:00 >15911i 2002/272-13:26:00 All of these were early in the pass; in only one case was there an earlier occultation without a problem reported. And in that case I looked up the plot and it DOES show modulation; it just wasn't reported because the modulation on the second occultation was much worse. The behavior would be consistent with erratic tracking of the ground antenna (overlapping coverage from DSS 65 in some of the cases shows no modulation). I thought about CONSCAN; I see MSPA (and therefore possible unexpected CONSCAN?) only on the DSN schedule for day 274. >The anomalies shown below were listed in recent health reports. >How serious is this modulation?

If you want the plots, they are on magellan:/users/z00/BRO; or I can send you hard copies. >The last measurement collected on day 272 at DSS 15 (occultation 15915i, >start time 2002/272-21:16:00) had a +0.5 dB ramp in the free-space >carrier. This is presumably something different. Including it will only confuse matters. Let's concentrate on the quasi-sinusoidal modulation. Thanks for picking up this pattern. With Kerri in and out, I've not been following this closely enough to notice; and she may not have been either.
