I-STOP INGRESS PROBE BY TRILITHIC / VIAVI 1.2 GHZ

DESCRIPTION

The Viavi TRI-ISTOP-1250MHZ I-Stop Reverse Test Probe, 1.25 GHz, is a test accessory you can use with signal level meters and analyzers for bi-directional measurements with no risk of power damage. Simply screw the probe into the unused KS port of a distribution tap and a spring-loaded "stinger" will connect a nominal 20 dB resistive test point circuit to the seizure screw. The connection is bi-directional, so that an SLM or analyzer connected to the probe can measure forward and reverse signals, as well as reverse ingress. Also, a built-in AC/DC blocking circuit protects the SLM or analyzer from damage from online power up to 100 volts.

The I-Stop reverse test probe is the fastest and safest way to track down reverse ingress with any device that can see the headend ingress view, all the while saving time and operational expenses.

FEATURES

  • Enables tracking reverse ingress to the nearest tap
  • Compatible with SLMs, reverse and forward path analyzers
  • Taps unused KS ports for bi-directional measurements
  • Protects instruments from line power damage (up to 100 volts)
  • Economical way to equip techs to track, find, and fix active ingress on live plant

Included Components

  • 1 - I-Stop Probe

Common Questions About the VIAVI I-STOP Ingress Probe

What is the VIAVI I-STOP ingress probe used for?
The VIAVI I-STOP ingress probe is used to safely identify and trace reverse ingress in live CATV networks by allowing bi-directional signal measurements at the tap without interrupting service.

Who uses an I-STOP ingress probe?
The I-STOP probe is commonly used by cable plant maintenance technicians and field engineers who troubleshoot upstream noise, ingress issues, and return path impairments.

Why is the I-STOP probe safer than direct connections?
The probe includes built-in AC and DC blocking that protects signal level meters and analyzers from line power up to 100 volts, reducing the risk of equipment damage during live plant testing.

How the I-STOP Probe Supports Reverse Ingress Troubleshooting

The VIAVI I-STOP Reverse Test Probe provides a fast and safe way to pinpoint reverse ingress at the tap. By connecting through an unused KS port and providing a resistive test point, it allows technicians to measure forward and reverse signals without disrupting service, helping isolate ingress sources more efficiently and reduce troubleshooting time.
