Useful comparative measurements can be made, however. Because the couplers employ diode envelope detectors, signals without a carrier would normally be distorted during demodulation. To account for this, we provide special test signals for these modes which add subcarriers to simulate the existence of a carrier. See usage guidelines in the User Guide for more details. While the LP-100A couplers look similar to the LP-500 couplers, they are completely different and are therefore not compatible. Important notice for LP-100A owners: LP-500 will not replace the LP-100A. The LP-100A will continue with some important features not provided in the LP-500.

which in this case show risetime of the cw envelope (1.6 ms). The
cursors work in all WFM modes and measure various parameters. The

Connecting Test Tone Output to Your Rig… The Test Tone output is
intended to feed a line level audio input of the rig. Some rigs have a
dedicated jack for this, but some of the newer rigs which have limited
space
for connectors don’t. Most rigs have a DATA connector, which is meant
to be
connected to a TNC or Sound Card RTTY interface. These usually take the
form of
a DIN or mini-DUN connector. Sometimes these are labeled ACC-1, ACC-2
or ACC-3.
The pins that you want to look for are usually labeled Data IN
and Gnd. These would connect
to the tip and sleeve of the audio jack on the LP-500. An alternative is to use the front panel MIC jack on the rig, either an 8-pin round or 8-pin modular (Ethernet type) connector. You will need an interface like the inexpensive W2IHY iBox to make this connection. The iBox accepts the unbalanced line level output of the meter, and converts it to any number of outputs to feed various connectors on your rig, either front panel or rear panel. Julius, W2IHY can direct you to the best option for your rig. It is generally preferred to use a rear panel connector so that the microphone (or mixer) can remain plugged into the front panel. This will usually allow you to have independent gain controls for the mic and meter levels, so that they can be matched. If the levels aren’t matched, adjustments made with the test tones will not correlate directly to microphone use. Here is Julius' information...
