• EVLA Bandpass Tool An EVLA antenna bandpass plotting program. This program logs into an antenna and determines the bandpass shape plotted against sky frequency. The core of this program was written by summer intern David Sevilla. This program can only be used from NRAO computers. Currently this only supports the 8-bit samplers. This program is purely parasitic so you will have to tune the EVLA antenna to the desired settings before running this using other software.
• Transition LOSER A tool to calculate L301 and L302 settings that place a certain sky frequency within the VLA bandpass. Enter either a band edge frequency or a center frequency and a bandwidth (all in MHz). All possible L301 and L302 tunings will be displayed. The one chosen by default will be indicated.
