Maintenance

Maintenance

This section contains maintenance information for your probe.

Error condition

The TAP1500 active probe is designed to work with all TekVPI-interface oscilloscopes and adapters. However, there may be some
cases where all of the probe features may not work properly.

If the Status LED glows red during or after probe power on, an internal probe diagnostic fault exists. Disconnect and reconnect the
probe to restart the power-on diagnostic sequence. If the Status LED continues to glow red, the probe is defective, and must
be returned to Tektronix for repair.

Replacement parts

There are no user replaceable parts within the probe. Refer to

Accessories

for a list of replaceable accessories for your probe.
