To prepare for connecting to RF
1.
NOTICE!
Damaged or not clean connections can lead to RF insertion loss and mis-
match, and even premature wear of the connectors.
Before connecting to the port, inspect the RF connector visually to check that it is
clean, undamaged and mechanically compatible.
See the application note
for information on how to handle and maintain the
RF port, to minimize measurement deviations and ensure its longevity.
2.
NOTICE!
Risk of instrument damage. Excessive reverse power or DC voltage at
the RF connector can damage the instrument.
Make sure that signal power and DC limits as given in the data sheet.
3. If the R&S
