The I-Stop reverse test probe is a test accessory you can use with signal level meters for bi-directional measurements with no risk or power damage.

  • Taps unused KS ports for bi-directional measurements
  • Compatible with SLMs and reverse and forward path analyzers
  • Protects instruments from damage caused by line power
  • Tracks reverse ingress to the nearest tap
Track reverse ingress down to the nearest tap

The I-Stop Reverse Test Probe is a test accessory that you can use with most signal level meters to take bi-directional signal measurements with no risk of power damage.

Just screw the probe into a distribution tap's unused KS port and a spring-loaded "stinger" connects a 20 dB resistive test point circuit to the hardline. The bi-directional connection lets a meter or analyzer measure forward and reverse signals, as well as reverse ingress. A built-in AC/DC blocking circuit protects the meter or analyzer from damage from online power up to 90 volts.

The I-Stop Probe also works with Trilithic's 860 DSPi and 9581 SST to let you track reverse ingress sources down to the nearest tap – without removing reverse modules or diplexers and without disrupting forward or reverse service.
