Can the P6139B be used on scopes that shipped with a P6139A? What is the difference between the P6139A and the P6139B?

Can the P6139B be used on scopes that shipped with a P6139A? What is the difference between the P6139A and the P6139B?

From a specifications perspective, the probes are identical. Both are 500 MHz, 10X passive probes. The P6139B can be used on oscilloscopes that shipped with the P6139A.

From a mechanical perspective, there are some differences:

- Sharper tip

- Ground spring attaches directly to the tip without the special sleeve used in the P6139A

- Alligator Ground lead attaches directly above the plastic sleeve and does not use the ground lead with the "donut"

- Sleek design

- Compliant to March 2011 safety updates (UL approved)

The TPP 0100, TPP 0101, TPP 0200, TPP 0201, TPP 0500, TPP 1000, and P6139B passive probes all share a common probe tip diameter, so the probe accessories work across all of the probes.
