X10 CODE IDENTIFIER: All 256 X10 unit codes and the 16 X10 function codes can be displayed. This simplifies identifying code transmissions and diagnosing faulty transmitters. In the example screen below, a code was sent to turn on an X10 module set to El 2.
Sample Screen
X10 CODE: E12 EON
SIGNAL STRENGTH: 89m 88m
X10 SIGNAL STRENGTH VOLTMETER: The signal strength, measured in volts, is displayed underneath each corresponding X10 code received. Above, the code E12 measured 89 millivolts in strength upon reception followed by the code EON at 88 millivolts. It's easy to see the effect on the transmitted signal strength due to changing loads, long transmission lines or installing couplers/repeaters.

NOISE: .5 ms: 9m
.2 to .9ms: 12m
POWER LINE NOISE METER: Strong electrical "noise" on the AC power line can interfere with X10 transmissions. X10 codes are placed on the AC power line at a frequency of 120 kilohertz for duration of 1 millisecond after each zero-crossing of the AC power line cycle. In this example, noise spikes of 100 kilohertz or greater at .5 milliseconds after zero-crossing measured 9 millivolts, and all spikes between .2 and .9 milliseconds measured 12 millivolts. This is useful when examining out the general electrical environment and to see if installed filters have diminished power line noise to acceptable levels.
Sample Screen
DISSECT: 1 0
CYCLE 02 1.4 03m
DISSECT THE ENTIRE X10 SIGNAL: Each X10 code is transmitted twice using 22 AC power line cycles. Each true bit of code information is transmitted at the zero-crossing point with a complement bit transmitted on alternate half cycles. All 22 true bits of the X10 code and their complements can be viewed. In this example, cycle #2 is dissected to show the true bit as a Binary 1 with a signal strength of 1.4 volts, and it's complementary bit (Binary 0) with signal strength of 3 millivolts. This is useful for seeing the effects on the X10 signal after installing repeater/amplifiers and for viewing additional codes or data after extended code/data/preset dim commands.

RECORDING NOW
#15 B14 1.2 01.7
X10 HISTORY RECORDER: CODE IDENTITY, STRENGTH AND TIME: Up to 190 X10 events can be recorded and stored in non-volatile memory to be played back a later date. The recorder stores the identity of the received X10 code, it's signal strength and the elapsed time from start of recording. Here, the latest code, #15, is B14 with a signal strength of 1.2 volts and was recorded 1.7 hours after recording started. This is useful for identifying macro contents and for capturing spurious or bothersome X10 signals at odd times.
