Front-Panel Operation
Connect the Calibrator to a UUT 4
4-5
Caution
To ensure the Product is not damaged, use only cables with
correct voltage ratings.
Table 4-1. Auxiliary Amplifier Data
Output Function Cable Recommendations
DC voltage
AC voltage ≤10 kHz
AC current ≤2 A, ≤10 kHz
DC current ≤2 A
Resistance
Low Thermal EMF Test Leads
[1]
5730A-7002 (banana plugs) or
5730A-7003 (spade lugs)
(If external sensing is necessary, use a twisted
shielded pair.)
AC voltage >10 kHz
SENSE/GUARD: Triaxial cable or Twinax (e.g.,
Alpha 2829/2), OUTPUT: Coaxial
Or: SENSE: Coaxial, OUTPUT: Coaxial
GUARD Lead: Separate wire
AC current with guard Triaxial cable
Wideband AC
3-foot (1 m) 50 Ω coaxial cable with type “N” male
connectors supplied with the option. A 50 Ω
feedthrough terminator is also supplied for
connecting to meters with an impedance >50 Ω.
Voltage-boosted output, 5725A
Low Thermal EMF Test Leads [Note 1]
5730A-7002 (banana plugs) or
5730A-7003 (spade lugs)
(Output is at the Calibrator front panel.)
Current-boosted output, 5725A
16-gauge or heavier twisted pair insulated wire,
as short as possible to minimize resistance and
inductance. (Output is at the amplifier terminals.)
Current-boosted output, 52120A
Refer to the 52120A manual for cable
requirements.
[1] Spade lugs provide a slightly better thermal EMF performance. However, some UUTs have repressed
banana connectors that cannot accommodate spade lugs.
