| BNCs. Are there any standards, even informal, for centre spacing of BNC layouts? |

I'm sure we all know that 4mm sockets on test equipment are often laid out on a 19mm/\$\frac{3}{4}\$" grid, to allow double plugs and the like to be used. There's no formal standard as such for this, but it exists as a loose industry standard. When it comes to BNCs (and other coaxial connectors) on test equipment they seem to be essentially randomly laid out. At least I've never been able to discern a pattern the way one quickly can just by looking at a few bits of kit equipped with 4mm connectors. Has anyone ever come across a similar gridding standard for BNCs, or for any coaxial connector system? The existence in broadcasting of coaxial 'U' links for patch panels implies there's a least one standard, for one type of coax connector. Does anyone know of a spacing/gridding standard, even informal, even "honoured more in the breach than the observance thereof", for BNCs? |

Having worked in cabling AV systems, I can tell you on dense patchbay in/out bnc jacks, you definitely want one of these... https://www.bhphotovideo.com/c/product/905755-REG/Platinum_Tools_11008_BNC_Economy_Removal.html |

Hmm, survey says... Wavetek 193 function generator: 34mm Wavetek 275 arb gen, front panel: 25.2mm Wavetek 275 arb gen, rear panel: 34 x 24mm grid Tektronix TDS460 scope, front panel: 33mm Tek 475 scope (rear panel): 19mm HP 8590A (front panel, 1st LO to CAL): 24.3mm Not seeing much consistency between my things at least...

I guess they could make these tighter, but not sure I want to work on it... |

The spacing on LCR meters seems to be standard. |
