Tightening RF cables
Tightening RF cables too strongly, can damage cables and connectors. Loose tighten-
ing can result in inaccurate measurement results.
Therefore always use an appropriate torque wrench, suitable for the type of connector.
Rohde & Schwarz offers an optional 5/16” torque wrench that fits for SMA, 3.5 mm,
2.92 mm and 1.85 mm connectors (R&S ZN-ZTW variant 35). Similar wrenches are
available for other sizes of spanner, too. For ordering information, see the R&S ZN-
ZTW data sheet or product brochure.
3.5.6.3 Diplexer control
Switchover between low frequency and high frequency mode is automatically control-
led from the R&S ZNA67EXT network analyzer unit. Use the "H/L Switch" cable to con-
nect the User Port connector on the rear panel of the analyzer to the H/L SWITCH con-
nectors on the top side of the diplexers.
