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 speci
fi
cations. 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.

The probe compensation box is near its maximum
operating temperature. Additional cooling, such as
an external fan, may be required.
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<x>: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
fi
bers
within a single cable between the compensation box and probe
head. Therefore, standard optical
fi
ber handling practices
are required. Avoid tight radius bends, crushing, crimping,
twisting, or otherwise stressing the
fi
ber.
Standard accessories
MMCX probe tip
The 10X MMCX tip is included in every TIVP probe. The MMCX tip is
recommended for the best bandwidth and CMRR performance. 0.100"

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
