The inputselect statement will lead to e.g. register settings off the FiLA10G to be overwritten.</div><div class="">This practically means that any call of fmset after loading the fullband mode procedure will overwrite the required setup. We are discussing at the moment options with Ed.</div><div class=""><br class=""></div><div class="">As a workaround the following sequence of commands is recommended when running in fullband mode:</div><div class="">1) first run fmset</div><div class="">2) then execute the fullband mode procedure</div><div class=""><br class=""></div><div class="">In the procedure statements any „reset“ commands should be called with the „keepsync“ option as otherwise the time synchronization will be lost again. </div><div class="">The instructions have been updated accordingly on the GMVA wiki pages:</div><div class=""><a href="https://deki.mpifr-bonn.mpg.de/GMVA/GMVA_Setups#ALMA_Mode_4_Gbps_(fullband_mode)" class="">https://deki.mpifr-bonn.mpg.de/GMVA/GMVA_Setups#ALMA_Mode_4_Gbps_(fullband_mode)</a></div><div class=""><br class=""></div><div class="">Note that this only applies if your FiLA10G is not equipped with the GPS module as otherwise calling fmset is not needed for time synchronization. </div><div class="">Regardless of the presence of a GPS module fmset should never be called after loading the fullband mode setup.</div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">Another test of the fullband mode is planned as part of the upcoming GMVA session. More detailed instructions will be circulated soon.</div><div class=""><br class=""></div><div class="">All the best,</div><div class="">Helge</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><span style="orphans: 2; widows: 2; text-align: -webkit-auto;" class=""><br class=""></span></div><div class=""><span style="orphans: 2; widows: 2; text-align: -webkit-auto;" class=""><br class=""></span></div><div class=""><span style="orphans: 2; widows: 2; text-align: -webkit-auto;" class="">------------------------------------------------------</span></div><div class=""><div class=""><div style="color: rgb(0, 0, 0); letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><div style="color: rgb(0, 0, 0); letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><span class="Apple-style-span" style="border-collapse: separate; font-variant-ligatures: normal; font-variant-east-asian: normal; font-variant-position: normal; line-height: normal; border-spacing: 0px;"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; border-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-stroke-width: 0px;"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; border-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-stroke-width: 0px;"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; border-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-stroke-width: 0px;"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><div class="">Helge Rottmann</div><div class="">Max-Planck-Institut für Radioastronomie</div><div class="">Auf dem Hügel 69</div><div class="">53121 Bonn</div><div class="">Germany</div><div class=""><br class=""></div><div class="">Tel: ++49 (0)228 525 123</div><div class=""><div class="">------------------------------------------------------</div></div><div class=""><br class=""></div><div class=""> </div></div></span></div></span></div></span></div></span></div></div>
