Example:

Output resistance of a frequency generator = 50 Ω.

Line resistance of coaxial cable used

= 50 Ω. Resistance value of terminating resistor

= 50 Ω.

In order to minimise the ripple voltage when

taking measurements, always connect the frame

earth of the circuit under test ("-" or housing) to

the frame earth of the oscilloscope (via a

screened cable with the BNC socket of the

relevant input CH 1 or CH 2).

2.2.3 Screen overlays, explanation

(1) "Real-time display"

Warning!

The frame terminals of the oscilloscope, the BNC

sockets (8), (9), (19), (30), (34) and the earth

connection (36) are connected directly to the

protective conductor of the mains input socket

or the connected power cord. Make certain that

the circuit in/on which you are making mea-

surements is electrically isolated from the mains

by a transformer. Never connect the (BNC)

inputs/outputs directly to the mains supply,

chassis that are live or circuits that are operated

without transformers (input electrically isolated

from output). Danger - risk of fatal injury.
