Installation

Connecting to the Host Instrument

NOTE. Your TekConnect instrument may

require a firmware upgrade to support full
functionality of these TriMode probes. Before
you connect the probe, check the version
requirements. (See page 53, Host Instrument
Firmware.)

1. Slide the prob e into the TekConnect
receptacle. The probe clicks into place
when fully engaged.

2. To disconnect, press the latch release
button and pull the probe away from the
instrument.

Installation

P7504 & P75 06 TriMode Probes Quick Start User Manual 3

Installation

Probe Power-On

When the prob e is powered on, all LEDs briefly
flash as the self-test routine runs, and then the

following LEDs remain lit:

5X Attenuation

A – B TriMode (Differential)

This indicates that the probe is in normal
operating mode.

NOTE. The host instrument sets all probe

settings to the last known state for the
probe/channel combination.

If none of the LEDs are lit, the instrument may
have detected an error condition. Disconnect
and reconnect the probe to clear the error.
(See page 54, Error Conditions.)

Connecting A ccessories to the Probe Body

CAUTION. The probe has replaceable contacts inside the probe body connector that may stick to the accessory connector when

it is disconnected. To prevent damage to the probe, before you connect accessories to the probe body, always check that the
contacts are located in the probe body only. For replacement procedures, see the P7504 & P7506 TriMode Probes Technical
Reference included on the documentation CD.

The probe body and tip cable ends are keyed
to ensure correct installation. Connect them
as follows:

1. Orient the probe body with the A and B
inputs on top, as shown.

2. Align the tip cable lead with the red band to
the A input.

Installation

Input Mode Button and LEDs

Press the Input Mode button to select one of
the four TriMode measurements. The modes
cycle in the following sequence:

A – B (for differential signal measurement)

A – GND (for A input single-ended

measurement)

B – GND (for B input single-ended

measurement)

(A+B)/2–GND(forcommonmode

measurement)

NOTE. Some oscilloscope models only allow

the A – B Input Mode to be selected, depending
on which input tip is selected in the oscilloscope
Probe Setup screen. (See page 56, Input Mode
Selection.)

The following pages discuss characteristics of
the TriMode measurements.

Functional Check and Calibration

Functional Check and Calibration

After you connect the probe to the oscilloscope, perform a functional check using the calibration board included with the probe.

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.

Functional Check

This procedure checks the four TriMode settings on the probe, using the PROBE COMPENSATION or FAST EDGE connection on
the front panel of the oscilloscope. The A-B (differential mode) is set up and verified first, and then the remaining input modes are
checked and compared to the differential mode measurement.

1. Connect the probe to any channel (1–4) of

the oscilloscope.

2. Set the oscilloscope to display the channel.

3. Connect an SMA cable from the Probe

Compensation or FAST EDGE output
connector on the oscilloscope to the SMA
connector on the TriMode DC Calibration
board.

4. Set the two output switches on the TriMode
