We already installed SAOtng, PGplot, and Perl in computers which will be required. I confirmed SAOtng can work properly. Since we already made a short program for making FITS files from the camera's raw data, we can test after the delivery of camera. RF link also been checked. The noise temperature of 200 and 300 GHz Inserts, integrated with the entire cryostat electronics, were measured.
Noise performance is reasonable.
We suspect this problem is also related to the mysterious interaction between SIS mixer and HEMT amplifier seen previously, which made the SIS I-V curve distortion. We will be needing another set of 200 and 300 GHz mixers soon. A subrountine was written to calculate the surface impedance of superconductor at different frequencies.
