Minimum requirements
Example
1.
Connectors
Connectors for hook up wire assemblies and test
resistors, item numbers 5, 6, 9, 10, and 11.
•
(Qty. 6) #10 fork lugs similar to Tyco part number
52951
•
(Qty, 14) Stackable, gold plated, banana plugs/jacks
similar to Pomona model 4897-0. Used for lower
current connections, and connection to the load
resistors (items 10 and 11) used for noise testing.
•
(Qty. 4) Sheathed banana jacks similar to Pomona
model 4834 to put connectors on the Resistors (item
9)
2.
AC power source
Variable AC output from 90 to 265 VAC with at least
750 VA capacity

4.
DC voltmeter
Voltage measurement at 12 mV through 72 V to better
than 100 ppm accuracy with the ability to multiply the
result by a scalar.

5.
High current hook up wire
(High current connections
are indicated with bold
lines in the setup
illustrations)
18 AWG (minimum) hookup wire assemblies. TO
perform all tests, the following wire assemblies need to
be created:
•
#10 fork lug to #10 fork lug, Qty 2, (included in
Guildline 92301 if used).
•
Stackable banana to #10 fork lug, Qty 2
Wire lengths are not critical.
6.
Low current hook up wire
(Low current connections
are indicated with light
lines in the setup
illustrations)
22 AWG (minimum) hookup wires
To perform all tests, the following wire assemblies
need to be created:
•
Banana plug to banana plug, Qty 2
•
Bare wire to stackable banana, Qty 2
•
Bare wire to banana, Qty 2
Wire lengths are not critical.

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 100 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.
