To perform the tests as illustrated, both leads of each
resistor require a Banana Jack connector (e.g. Pomona
model 4834).

Load resistor for Voltage
Noise testing
Loading resistors for high current in voltage mode, and
high voltage in current mode
All resistors should be rated for at least 50 W. Ohms
tolerance within 5%. Resistor composition is not critical.
To perform the tests as illustrated, both leads of the load
resistor require a Banana plug/jack (or equivalent) to
connect to the power supply.
