SGP/MWR/B1 - occasional negative brightness temperatures
DataStreams:sgpmwrlosB1.00, sgpmwrlosB1.a1, sgpmwrlosB1.b1, sgpmwrtipB1.00, sgpmwrtipB1.a1
Description:
Occasional spikes in the MWR data were observed. Inspection of
the data indicates that these are due to spikes in the gain that result from
either unrealistically low values of the blackbody target temperature (~150 K) or
unrealistically low values of the microwave signal counts when viewing the
blackbody target. Unrealistically low values of the mixer temperature have also been
observed.

by pointing the mirror at an internal blackbody target.  The

SGP/MWR/C1 - Intermittent Negative Sky Brightness Temperatures
DataStreams:sgp1mwravgC1.c1, sgp5mwravgC1.c1, sgpmwrlosC1.a1, sgpmwrlosC1.b1
Description:
Several related and recurring problems with the SGP MWRs have been
reported dating back to 1999.  These problems were due to the
occurrence of blackbody signals (in counts) that were half of those
expected. The symptoms included noisy data (especially at Purcell),
spikes in the data (especially at Vici), negative brightness
temperatures, and apparent loss of serial communication between the
computer and the radiometer, which results in a self-termination of the
MWR program (especially at the CF).

Because these all initially appeared to be hardware-related problems,
the instrument mentor and SGP site operations personnel (1) repeatedly
cleaned and replaced the fiber optic comm. components, (2) swapped
radiometers, (3) sent radiometers back to Radiometrics for evaluation
(which has not revealed any instrument problems), and (4) reconfigured
the computer's operating system.  Despite several attempts to isolate
and correct it, the problem persisted.

It became apparent that some component of the Windows98 configuration
conflicted with the DOS-based MWR program or affected the serial port
or the contents of the serial port buffer. This problem was finally
corrected by upgrading the MWR software with a new Windows-compatible
program.
