Subject: | NSA/MWRP/C1 - Hardware failure- Intermittent data |
DataStreams: | nsamwrpC1.b1 |
Description: | Data are intermittent during this time due to a failure of the analog board. The calibration of V-band data may have slightly drifted due to power outages. |

Subject: | NSA/MWRP/C1 - Thermal instability- TKnd test |
DataStreams: | nsamwrpC1.b1 |
Description: | During this time the radiometer was thermally unstable . The noise diode physical temperature had sudden drops of more than 5 degree in several ccasions between 2/1 and 2/11. On 2/12 the radiometer temperature set point was lowered of about 10 degree as a test. On 2/27 a new analog board was installed in the instrument. Data after 2/27 show a slight change in calibration. |
