HD SDI-Signalverlust durch MK-V Nexus 2 Post-Elektronik, während Composite-Video funktioniert einwandfrei
Was die Diskussion ergab
- Die MK-V V3-Elektronik hat ein HF-Interferenzproblem, das HD SDI-Signale betrifft, die durch nicht abgeschirmte Steckverbinder innerhalb des Posts reisen, insbesondere mit 1,5 GHz- oder 3 GHz-Signalen.
- Das Upgrade von V3 zu V3.5 fügt eine interne Steckerabschirmung hinzu, um das Problem der HD SDI-Signalinterferenz zu beheben.
- V4 electronics introduced in 2012 feature redesigned internal cabling and additional SDI lines that eliminate the shielding issues present in V3 versions.
- Using a signal converter to transform HD to composite video allows the signal to pass through the post without loss as a workaround.
- The external appearance difference between V3 and V3.5 is minimal—only an engraving—making it important to verify the upgrade was actually performed internally.
Hängt ab von
- The problem appears specific to the V3 electronics generation.
- The workaround using a converter device may introduce additional equipment into the signal chain.
- Users considering a used sled need to inspect internal modifications since external markings alone cannot confirm an upgrade was completed.
- The RF interference susceptibility depends on the presence of RF sources in the immediate working environment.
