Installation
Installation
Before you connect the probe to your instrument, read the Overview below to understand the sequence of events necessary to
properly install the probe and adapters.
CAUTION. To avoid ESD damage to the probe, always use an antistatic wrist strap (provided with your probe), and work at
a static-approved workstation when you handle the probe.
Overview
1. Connect the probe to the host instrument.
If it is the first time the probe has been connected to the oscilloscope, the oscilloscope will download the S-parameters stored in
the probe. Once the oscilloscope has stored the S-parameters for the probe, it doesn’t matter which channel the probe is
plugged into. The stored S-parameters will be available for any channel the probe is moved to.
2. Connect the probe tip to the TekFlex connector on the probe.
When a tip is inserted into the probe for the first time, the oscilloscope will download the S-parameter data stored in the tip.
3. The probe performs a self test, and then one Input Mode LED remains on.
4. Open the Calibration menu (found in the Vertical menu).
5. Perform the DC probe calibration procedure using the DC probe cal fixture that ships standard with each probe. (See page 18,
TriMode probe DC calibration.)
6. Use the Probe Setup screen to set the probe parameters as described in the Basic Operation section.

Installation
Connect to the host instrument
NOTE. Your TekConnect instrument may
require a firmware upgrade to support full
functionality of the P7700 Series probes.
Before you connect the probe, check the
version requirements. (See page 74, Host
instrument firmware.)
1. Slide the probe into the TekConnect
receptacle. The probe clicks into place
when fully engaged.
2. Optional. Turn the thumbscrew clockwise
(finger-tight only) to secure the probe to
the instrument.
Disconnect
3. To disconnect, turn the thumbscrew
counter-clockwise.
4. Press the latch release button and pull the
probe away from the instrument.
P7700 Series TriMode Probes User Manual 5

Installation
Probe and probe tip power-on
After the connection to the oscilloscope is
made:
1. The probe briefly turns on all LEDs during
a self-test, and then the A – B Input Mode
LED remains on. If a probe tip is attached,
an LED on the tip also turns on when
properly attached to the probe.
2. The probe transfers data from the probe
and tip to the host instrument, and a
message displays on the instrument as the
transfer occurs.
The data transfer takes a few minutes,
and is only done when the host instrument
discovers a new probe or new probe
tip. The data transfer only occurs on
instruments that are fully compatible with
the probe.
3. After the data transfer is done, the probe is ready for a functional check and calibration. (See page 11, Functional check.)
NOTE. If the probe’s warning light remains on, the power-on self-test likely failed.
(See page 76, Error conditions.)
