The RA0062 is a 20 pF input adapter for 1/2" preamplifiers. One end screws on to a 1/2" preamplifier and the other end has a BNC input connector. This enables connecting a signal generator to the input of the preamplifier.
Short circuiting the BNC input results only in loading the preamplifier by 20 pF. For this purpose a BNC plug with a built-in 50 ohm resistor is enclosed. This plug is used when measuring the noise floor in the preamplifier.
