carton having inside dimensions at
least one inch greater than the probe
dimensions. The box should have a carton
test strength of at least 200 pounds.
2. Put the probe into an antistatic bag or wrap
it to protect it from dampness.
3. Place the probe into the box and stabilize it
with light packing material.
4. Seal the carton with shipping tape.
5. Refer to Contacting Tektronix at the
beginning of this manual for the shipping
address.

Installation
Installation
Connecting to the host instrument
NOTE. Your TekVPI instrument may require a
firmware upgrade to support full functionality
of the TDP3500 and TDP4000 probes. Before
you connect the probe, check the version
requirements. (See page 36, Host instrument
firmware.)
1. Slide the probe into the TekVPI receptacle.
The probe snaps when fully engaged.
When you connect the probe, the host
instrument reads information from the
probe and identifies the probe type.
2. To disconnect, press the latch release
button and pull away from the instrument.

Installation
Probe controls and indicators
Status LED
When the probe is powered on, the Status
LED glows green, then dark, and then remains
lit green. This indicates that the probe is in
normal operating mode.
If the Status LED glows red, a fault may exist.
To clear the fault:
1. Disconnect the probe from the oscilloscope.
2. Reconnect the probe to the oscilloscope.
If the Status LED continues to glow red, return
the probe to Tektronix.
