EVLA/VLBA/GBT Resources

NRAO Interactive Services Modification Request 1 S1 2012



1. Introduction

Any changes to the telescope specific resources

2. Background

3. Requirements

EVLA

  • Convey total bandwidth on the EVLA cover page for OSRO Modes. The text should be: "Total Bandwidth: BW MHz" where BW is the total bandwidth. Since each OSRO mode has two independently tunable basebands, each with 8 sub-bands then BW = 16xsub-band bandwidth. The only exception is for OSRO2 where BW will equal the sub-band bandwidth.

  • Remove "move" selections from Configuration drop-down menu in VLA Resources: D=>DnC, DnC=>C, C=>CnB, CnB=>B, B=>BnA, BnA=>A, A=>D.

VLBA

  • Aggregate bit rate needs to be passed to pdf of proposal.

  • Aggregate bit rate of 1024 Mbps needs to be disallowed with a pop-up warning.

  • User-selected stations need to be passed to pdf of proposal.

GBT

  • Receivers
    • W-band Shared Risk (68-92 GHz): The frequency range for this receiver is now 67-93.3 GHz but broken up into different ranges (similar to the Ka-band receiver). In resources please replace "W-band Shared Risk (68-92 GHz)" with the following four selections:
      • W-band MM1 (67-73.5 GHz) (default 70.0 GHz)
      • W-band MM2 (73.5-80.5 GHz) (default 75.0 GHz)
      • W-band MM3 (80.5-85.5 GHz) (default 82.0 GHz)
      • W-band MM4 (85.5-93.3 GHz) (default 90.0 GHz)
    • Ku-band (12 - 15.4 GHz): This receiver is being modified and is now a shared risk receiver. Please replace the name "Ku-band (12-15.4 GHz)" with "Ku-band Shared Risk (12-18 GHz)".
    • Add a new receiver called "C-band (5.85-8 GHz)" with a default frequency of 7.0 GHz. So now there will be two C-band receivers: "C-band (5.85-8 GHz)" and "C-band (3.95-5.85 GHz)"
  • GBT XML File. We do not want this to change so please make sure of the following:
    • The selection of any of the four W-band receivers will be called "W-band Shared Risk (68-92 GHz)" in the XML file.
    • The selection of "Ku-band Shared Risk (12-18 GHz)" will be called "Ku-band (12-15.4 GHz)" in the XML file.
    • The selection of either C-band receiver ["C-band (5.85-8 GHz)" or "C-band (3.95-5.85 GHz)"] will be called "C-band (3.95-5.85 GHz)" in the XML file.
  • Resource validation. Please contact MikeMcCarty (mmccarty@nrao.edu or 304-456-2128) for information about better error checking of GBT resources. Mike has some code from the sensitivity calculation that might be of use.

4. Design

Technical lead should provide a brief description of how this will be implemented in the code.

5. Deployment Checklist

Documentation? Systems/hardware/networking things needed for deployment?

6. Test Plan

6.1 Internal Testing

6.2 Sponsor Testing

6.3 Integration/Regression Tests


Signatures

APPROVED: I acknowledge that my request is fully contained in this MR, and if the Open Sky (or other NIS or PST developers) deliver exactly what I specified, I will be happy.

ACCEPTED: I acknowledge that I have validated the completed code according to the acceptance tests, and I am happy with the results.
