Installation
Installation
Before you connect the probe to your instrument, read the following Operating considerations and Overview sections to understand the
operating characteristics and 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.

Installation overview
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.
1. Connect the probe to the host instrument.
P7700 Series TriMode™ Probes 14
Installation
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 optional DC probe cal fixture. See TriMode probe DC compensation
on page 24.
6. Use the Probe Setup screen to set the probe parameters as described in the Basic operation section.
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 Host instrument firmware on page 48.
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
1. To disconnect, turn the thumbscrew counter-clockwise.
2. Press the latch release button and pull the probe away from the instrument.
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.
P7700 Series TriMode™ Probes 15
Installation
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 compensation. See Functional check on page 21 . If the
probe’s status LED is red, the power-on self-test likely failed. See Error conditions on page 49.
Connect accessories to the TekFlex connector
All of the P7700 accessories mate with the new TekFlex (zero insertion force) connector. This connector provides an easy connection with
one handed operation for attaching to the P7700 series accessories. The following procedures show the steps for connecting probe tips to
the TekFlex connector; the procedures for connecting to other accessories are similar.
Connect the tip to the probe TekFlex connector as follows:
1. Pinch the TekFlex connector to open the jaws.
2. Orient the tip with the probe head (notch to the left) and slide the tip connector into the TekFlex connector.
A green LED will light up when the tip is inserted. The LED is the first indication that the tip is powered and is inserted. You also need
to confirm that the connector pins on the TekFlex connector fit through the alignment holes on the tip.
3. Once the tip is fully inserted, release the pinch and the TekFlex connector closes. When closed and properly seated, the top of
connector will be flush with the probe tip housing.
