EVLA Memo 131 Measurements of C-Band EVLA Antenna Polarization
نویسنده
چکیده
A simple method for determining absolute antenna cross-polarization is described. Observations using this method were taken at C-band and the results are shown. The wide-band EVLA circular polarizers have high cross-polarization, exceeding 5% at most frequencies on most antennas. However, orthogonality between the RCP and LCP outputs is maintained, resulting in baseline-based cross-polarization of typically 5%.

EVLA Memo 123 The Effect of the 4-Band Dipoles on L, C, and X Band Performance
Test observations show that the deployable 4-band dipoles degrade VLA antenna sensitivity by approximately 7% at L-band, 8% at C-band, and 6% at X-band. The loss at higher frequencies is unknown, but is expected to be less. The dipoles also introduce a variability of 1 – 3% in the antenna cross-polarization at L-band only. This variability will degrade L-band polarimetry capabilities, limiting ...
متن کاملEVLA Memo #100 Correction of errors due to antenna power patterns during imaging
Errors in the observed visibilities can be classified as direction dependent and direction independent effects. Since direction dependent effects are different for each source, they must be corrected during imaging. This memo is concerned with the problem of correcting for such effects during imaging. We demonstrate that the effects of known receptor pointing errors (including polarization squi...
متن کاملEVLA Memo 103 Performance Tests of the EVLA K- and Q-Band Systems
Sensitivity measurements performed on EVLA antenna #14 show that the cold-sky zenith system temperature is about 45K for the 18 – 26 GHz band, and 60 K for the low frequency end of the 40 – 50 GHz band, rising to 95 K at the high frequency end. Efficiency measurements based on the planet Venus show the antenna efficiency to be about 50% in the 18 – 26 GHz band, and about 28% for the 40 – 50 GHz...
متن کاملEVLA Memo #152 Characterizing the Sensitivity of the EVLA at L-band
We present sensitivity measurements of the EVLA at L-band between 0.95 and 2 GHz. These are obtained using three EVLA antennas that are equipped with the final, EVLA-compliant L-band receivers. The reported SEFD values meet and/or exceed the EVLA sensitivity requirements over about 70% of the band, but are too high by 12–38% over the frequency range 1425–1750 MHz.

Of all the anticipated imaging problems to be undertaken by the EVLA, the most demanding, both in terms of data rate, data storage and post-processing, will likely be that of wide-band, wide-field imaging imaging the entire antenna primary beam with the full bandwidth. In this memo, I summarize the correlator requirements for various observing scenarios with the EVLA: distortion-free imaging of...
