Tektronix TIVP IsoVu Measurement System Instruction Manual

Tektronix TIVP IsoVu Measurement System

Operating information

The Tektronix TIVP IsoVu™ Measurement System offers a completely galvanically isolated (optical isolation) system. Isolation is used to greatly increase the accuracy of differential measurements with rapidly slewing reference voltages and to isolate hazardous voltages from the oscilloscope.
The TIVP is designed for use with Tektronix 4/5/6 Series MSO Oscilloscopes running software version 1.28 or higher.
Refer to the TIVP User Manual (071-3692-xx) for complete operating information and product specifications. The manual is available for download at www.tek.com/downloads.
The following illustration shows how to connect the probe to your instrument and the controls on the compensation box.

Controls and indicators

STATUS indicator.

SELF CAL button and LED indicator. Press to start self-calibration routine.

INPUT Termination button and LED indicator. With no tip attached, press to toggle the sensor head between 50 Ω and 1 MΩ termination.

ALT Mode indicator.

Compensating the probe

The TIVP contains a self-calibration routine that corrects Gain Accuracy, DC offset, and frequency response. These parameters change as the probe warms up to its operating temperature and remain constant once the temperature reaches steady-state. An indicator LED on the probe compensation box and the SELFCAL:STATE? PI command both indicate whether a self-calibration is RECOMMENDED, RUNNING, or PASSED.
Before making critical measurements, run SELF CAL to ensure the TIVP is compensated. The sensor tip does not need to be removed from the test point to successfully complete a self-calibration.

1. Connect TIVP to an oscilloscope channel.
2. Press the SELF CAL button on the probe compensation box. Alternatively, send the CH:PROBE:SELFCAL EXECUTE PI command to start the self-calibration programmatically.

• The SELF CAL LED will blink while the self-calibration is in process.
• The SELF CAL LED is amber when there is a change and a self-calibration is recommended. The LED is green if the last self-calibration is still valid.

Cable handling

Tektronix TIVP probes operate using several optical fibers within a single cable between the compensation box and probe head. Therefore, standard optical fiber handling practices are required. Avoid tight radius bends, crushing, crimping, twisting, or otherwise stressing the fiber.

Clearance requirements

The unique common mode voltage range of the measurement system allows it to be used in the presence of high frequency/high voltage common mode signals. It is important to observe all precautions while using this product.

WARNING. Electrical shock can occur while using this measurement system. The system is intended to isolate the operator from hazardous input voltages (common voltages); the plastic case of the sensor head and the shield on the sensor tip cable do not supply safe isolation. Maintain the safe clearance from the sensor head and sensor tip cable while the measurement system is connected to the energized circuit as recommended in this document. Do not access the RF Burn Hazard Zone while taking measurements on a live circuit. RF burn hazard zone is 1 meter (40 in) on all sides

Pollution degree descriptions

A measure of the contaminants that could occur in the environment around and within a product. Typically the internal environment inside a product is considered to be the same as the external. Products should be used only in the environment for which they are rated.

• Pollution degree 1. No pollution or only dry, nonconductive pollution occurs. Products in this category are generally encapsulated, hermetically sealed, or located in clean rooms.
• Pollution degree 2. Normally only dry, nonconductive pollution occurs. Occasionally a temporary conductivity that is caused by condensation must be expected. This location is a typical office/home environment. Temporary condensation occurs only when the product is out of service.
• Pollution degree 3. Conductive pollution, or dry, nonconductive pollution that becomes conductive due to condensation. These are sheltered locations where neither temperature nor humidity is controlled. The area is protected from direct sunshine, rain, or direct wind.
• Pollution degree 4. Pollution that generates persistent conductivity through conductive dust, rain, or snow. Typical outdoor locations.

Pollution degree rating
Pollution degree 2 (as defined in IEC 61010-1). Rated for indoor, dry location use only.
IP rating
IP20 (as defined in IEC 60529).
