Preface

Product description

The Tektronix TIVM Series IsoVu Measurement System offers a completely

galvanically isolated (optical isolation) system. The system consists of a sensor

tip cable, a sensor head, a controller, and a TekVPI interface as shown in the

following ﬁgure. Hazardous voltages in the sensor head are completely isolated

from the con

troller and oscilloscope by optical ﬁber cables.

Figure i: TIVM Series IsoVu Measurement System

Comp box

The TekVPI compensation box (Comp box) connects the measurement system

to one of the input channels on the oscilloscope. Power is supplied to the

asurement system through the TekVPI interface of the oscilloscope.

Controller

The controller connects to the oscilloscope through a coaxial cable and the C omp

box. Buttons and indicators on the controller provide a means for controlling the

easurement system and indicating the overall status.

x TIVM Series Measurement System User Manual

Preface

Sensor head

The sensor head

provides an interface between the device-under-test (DUT) and

the controller. It contains an electro-optic converter that converts the electrical

signal from the sensor tip cables to an optical signal sent to the controller.

Sensor tip cables

Different se

nsor tip cables are available to connect the measurement system to

the DUT. The sensor tip cable consists of an SMA connector that connects to the

sensor head; two screws to secure the sensor tip cable to the sensor head; the other

end of the sensor tip cable connects to the DUT through an MMCX connector

and optional adapters.

Operating considerations

Read this

section before installing your measurement system to be aware of the

operating requirements and clearance requirements including possible hazardous

areas when the measurement system is c onnected to the DUT.

Measurement syste m

handling best practices

The mea

surement system consists of quality parts and should be treated with care

to avoid damage or degrading the performance due to mishandling. Consider the

following precautions when handling the ﬁ ber-optic cables and sensor tip cables:

Do not crush, crimp, or sharply bend the ﬁber-optic cable. Avoid making

loops in the ﬁber-optic cable smaller than 5 inches (12.7 cm).

Do not twist the ﬁber-optic cable; twisting the cable will stress the optical

ﬁbers.

Do not allow kinks or knots to develop in the ﬁber-optic cable.

Avo

id putting tension on the ﬁber-optic cable.

Do not pull or jerk the ﬁber-optic cable, especially when kinks or knots are

esent.

Do not drop the sensor head or c ontroller assembly since damage and

isalignment of the internal optical components can result.

Avoid over-bending the sensor tip cables; do not exceed the minimum bend

radius of 2.0 inches (5.1 cm).

Avoid crushing the cables by accidentally running over the cable with a chair

wheel or by dropping a heavy object onto the cable.

Never support the weight of the sensor head or c ontroller b y the ﬁber-optic

cable.

Store the measurement system in the supplied carrying case when not in use.
