The three XL current probes add both convenience and expanded current measurement capability. The XL probes are designed to operate with the AM503B and AM5030 Current Probe Amplifiers. They are incompatible with the older AM503 and AM503A amplifiers. The XL (for extra long) probes have eight-meter cables, which allow you to reach test points on large devices such as heavy duty motors or automobiles. In addition, connecting to test points on transportation platforms such as trains, ships, or aircraft is much easier with the XL probes.

The A6302XL and A6303XL are modified versions of the A6302 and A6303 probes. The A6302XL can measure 20 A continuous (50 A peak) signals from DC to 17 MHz. The A6303XL can measure 100 A continuous (500 A peak) signals from DC to 10 MHz.

The A6304XL is rated for 500 A continuous (700 A peak) and is the same size as the A6303XL. The A6304XL has a bandwidth of DC to 2 MHz and is especially well suited for measurements on high-performance inverters, motor drives and other high current switch-mode control devices. The eight meter cable makes it very easy to access test points on devices physically separated from your measurement instrument.
