The gain settings probably looked good at the beginning. The A/D converter levels were about 8 dB below where they would clip; the spectrum has some spurs, but they don't appear severe. Over the first 90 minutes, the carrier level became stronger and eventually reached the level where clipping occurred. You can also see this in the power spectra. After about 30 minutes of clipping, the carrier level decreased and stayed below the clipping level for about 30-40 minutes. Eventually the signal resumed clipping and it appears it stayed in this range for most of the remainder of the pass -- about 3 hours, though the final hour may be better than the first two. Artifacts are visible in the power spectra during this time. The histogram is dominated by the end values, so it's hard to say anything about the distribution of sample values in the center. There is also evidence for 'sweeping' with most of the activity concentrated in approximately 11:30-12:00 UTC. This may have been a difficult weather day. Whereas the X-band signal strength varied only over about 0.5 dB on day 192, the total variation on day 200 was closer to 12 dB. Over intervals of an hour, changes of up to 2 dB were typical. Although the clipping is the most obvious feature in the quick-look plots, I think these data might have been useful for science if we were doing occultations. There will obviously be distortion, but the clipping was probably not so severe that it destroyed the character of the signal. Instead, we probably would have lost a few dB in SNR. In a real occultation, of course, we would not have been recording for 6-1/2 hours and might have noticed that the carrier level was creeping up.

I do not yet have a 2-way steering coefficient generator in place, but I did filter/decimate the 2-way data in multiple stages and remove low order (1st or 2nd) polynomial fits to the frequency residuals for the purpose of estimating the 2-way Allan deviation. The results may be found in the four tables below. The frequency scaling in the first two cases was relative to the S-band downlink and in the last two cases was relative to the X-band downlink. Each table also includes a measure of the nominal SNR over the duration of the recording. Due to dropouts in the frequency residuals, the recordings were each truncated in some fashion so as not to bias the frequency stability estimates. ****************************************************************************** Table 1 2003/192 (31920741.RSR): 07:41:00 for 01:09:54 (truncated before dropout) DSS 24: S up/S down Nominal SNR 62 dB/Hz T, sec Allan Deviation 0.256 1.367e-12 0.512 9.594e-13 1.024 7.372e-13 2.048 5.650e-13 4.096 4.586e-13 8.192 4.370e-13 32.768 3.631e-13 131.072 3.155e-13 524.288 2.026e-13 ****************************************************************************** Table 2 2003/192 (31920922.RSR): 09:22:10 for 03:10:03 (truncated before dropout) DSS 24: S up/S down Nominal SNR 63 dB/Hz T, sec Allan Deviation 0.256 1.512e-12 0.512 1.118e-12 1.024 8.807e-13 2.048 6.907e-13 4.096 5.462e-13 8.192 4.471e-13 32.768 2.845e-13 131.072 2.339e-13 524.288 1.852e-13 ****************************************************************************** Table 3 2003/192 (3192074B.RSR): 09:00:00 for 03:31:54 (truncated between dropouts) DSS 24: S up/X down Nominal SNR 60 dB/Hz T, sec Allan Deviation 0.256 1.176e-12 0.512 9.185e-13 1.024 7.085e-13 2.048 5.439e-13 4.096 4.445e-13 8.192 3.575e-13 32.768 2.640e-13 131.072 1.611e-13 524.288 1.025e-13 ****************************************************************************** Table 4 2003/200 (32000724.RSR): 09:30:00 for 02:28:33 (truncated between dropouts) DSS 15: X up/X down Nominal SNR 65 dB/Hz T, sec Allan Deviation 0.256 4.920e-13 0.512 2.717e-13 1.024 2.121e-13 2.048 2.125e-13 4.096 2.130e-13 8.192 1.973e-13 32.768 1.319e-13 131.072 6.694e-14 524.288 6.390e-14 ****************************************************************************** - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - From rsimpson@magellan.stanford.edu Sat Aug 30 18:23:23 2003 Date: Sat, 30 Aug 2003 18:23:19 -0700 (PDT) From: Dick Simpson 723-3525 To: hinson@rocc.stanford.edu, joe@neptune.stanford.edu, len@nova.stanford.edu, paetzold@geo.uni-koeln.de, rsimpson@magellan.stanford.edu Subject: MaRS Test Results Martin: Joe Twicken has computed Allan Deviation at several time intervals for the four RSR data files we have received from Sami's group.
