Description
The Model CA-554 is a high-voltage triax cable assembly that is terminated on either end with a male high-voltage
triax connector.
Figure 1: Model CA-554-.5
You can order the cable in four different lengths (see table below).
Model Cable length
number
CA-554-.5 1.64 ft (0.5 m)
CA-554-1 3.28 ft (1.0 m)
CA-554-2 6.56 ft (2.0 m)
CA-554-3 9.84 ft (3.0 m)
This cable assembly can be used with the Models 2657A High Power System SourceMeterInstrument, 8010
High Power Device Test Fixture, 2657A-PM-200 External Protection Model, and 2657A-LIM-3 LO Interconnect

Model CA-554
Electrical characteristics
Rated voltage: 3300 V
Rated amperage: 2.0 A
Leakage current:
Center to guard: < 100 x 10-12 A at 3000 V (see NOTE below)
Guard to shield: < 100 x 10-9 A at 3000 V
Full continuity:
Center to center
Guard to guard
Shield to shield
Dielectric breakdown voltage:
Center/guard to shield: 5250 V
With the Model 2657A System SourceMeterInstrument, the voltage between the Guard and HI
(inner shield and center conductor) will typically be less than 1 V under steady-state conditions. This
results in much lower leakage current between the cable's inner shield and center conductor.
