Host Instrument Firmware

Some instruments may require a firmware upgrade to support full functionality of the latest probes that are offered by
Tektronix. Instruments with lower versions of firmware may not display all probe controls and indicators on screen, and in
some cases may require you to power-cycle the instrument to restore normal instrument operation. If you are having problems
with your probe and suspect that you need to upgrade your instrument firmware, go to www.tektronix.com/probe-support
to download the latest firmware.
To check the firmware version on Windows-based instruments, from the menu bar, click Help/About TekScope. On
Linux-based instruments, press the Utilities button on the front panel.

Error Conditions

LEDs Do Not Remain Lit
If none of the LEDs remain lit after you connect the probe, a probe/oscilloscope interface fault may exist. Perform the
following steps until you clear the fault or isolate the problem:
If you are using a P5200A probe, check that the DC adapter is plugged in and functional.
Disconnect and reconnect the probe to restart the power-on diagnostic sequence.
Connect the probe to a different channel on the oscilloscope.
Disconnect the probe from the oscilloscope, power-cycle the oscilloscope, and then reconnect the probe.
Connect the probe to a different oscilloscope.
If the symptoms remain (they follow the probe), then the probe is defective and must be returned to Tektronix for repair.
Signal Display
If the probe is connected to an active signal source and you do not see the signal displayed on the oscilloscope:
Check that the probe accessories that you are using are fully mated.
Check the probe connection on your circuit.
Perform a functional check on the probe.
