  • Displays signal strength (8mV to 4V+) of all incoming codes
  • Analyzes AC powerline noise
  • Dissects each X10 code to examine all bits of code

Essential Info

The X10 Powerline Signal Analyzer is a serious troubleshooting tool. Because of its utility, it is essential for anyone with extensive X10 installations. Being able to dissect X10 signals down to the bit level provides the ability to examine the before/after effect of X10 repeater/amplifiers. The X10 Powerline Signal Analyzer also comes with a comprehensive manual that explains X10 signal theory and how to analyze it.

    If you are going to work with x10 this is the tester to get. I have used it for years. People think i am magical. not I just use the best tester made. I would still have one but some one stole it out of my truck.

    Menus flakey, sometimes non operative. I may return it. --M.
    JAMES -- reno, NV   8/8/2008
    It works as advertised but takes some interpretation to use correctly-not as user friendly as I expected
    GORDON -- west olive, MI   7/21/2007
    Very useful.
    MALCOLM -- rochester, MN   3/25/2005
    Nice unit, does what it's suppose to do
    STEVEN -- la palma, CA   1/28/2005
    Works great, can really see the signal difference when the filters are plugged in. great testing tool
    Dennis -- USA   12/19/2004
    I have tried 3 of the signal testers and this I found to be the best and worth the money. It allows logging up to 190 signals and their voltages to track down intermittent problems. Use the 5 & 10 amp FilterLinc on any device in the home that causes signal absorption.

    If you are having problems with your X-10 system this unit is ideal. It is worth the price. I had a problem with my system and this was the only way I could track it down (see below). If you are having problems with your system or even if it is not as reliable as you would like this is the unit to buy. You can then add noise filters to block noise but more impotantly reduce signal absorption. Couplers and boosters/amplifiers can also be added. I tried the less expensive unit for about $100 but it was not as useful as it did not give signal and noise voltages. Another problem was that in the history mode it would not display signal strength if a BoosterLinc is installed. The unit for $300 was suggested but it does not log a history of the strength of the signals. I first installed an ApplianceLinc 2002STW3 2-Way for its quietness. The module would turn on without reason and fail to respond to an off command. In addition, devices began to fail throughout my house. I then installed a 2002SHL3 1-Way and had the same problems. I purchased this 4814 Signal Tester and found that plugging in just 1 of these modules dropped the signal strength from about 2.5 volts to 0.5 volts or less. There was very little line noise measuring about 0.5 mV. The standand appliance modules work fine with no measurable loss of signal strength (I just wish they were more quiet). I believe that there is a severe problem with these modules in absorbing X-10 signals.

    This instrument is an absolute delight. A must for any serious X10 enthusiast. Pricy but worth every penny.
    LEE -- littleton, NC   2/7/2004
    Great device. Learned much about my X-10 environment and X-10 signals in general. Would be better if there was control over which command the Signal Dissect function examines. Such as the last history command being displayed (not recorded).
    LUDWIG -- libertyville, IL   1/30/2004
    Works great, excellent test tool. Would be nice to be able to download readings to PC.
    CARDIN A. -- seminole, FL   9/24/2003
    Great Tool!!! Have been able to diagnose a number of small problems that I never had the ability to do previously. Even though this device is quite pricey, I believe it was a good investment for my system maintenance.
    JACK A -- madison, CT   8/27/2003
    Being I long-time customer of Smarthome, I have learned to have pretty high expectations for my experiences with the company. I have never been disappointed.
