Generates a 1004 Hz test tone at 0dbm (mu-law).


Generates a 1004 Hz test tone.

By default, this application does not provide a Milliwatt test tone. It simply plays a 1004 Hz tone, which is not suitable for performing a milliwatt test. The 'm' option should be used so that a real Milliwatt test tone is provided. This will include a 1 second silent interval every 10 seconds.

Previous versions of this application generated a constant tone at 1000 Hz. If for some reason you would prefer that behavior, supply the 'o' option to get the old behavior.


  • options

    • m - Generate a 1004 Hz Milliwatt test tone at 0dbm, with a 1 second silent interval. This option must be specified if you are using this for a milliwatt test line.

    • o - Generate a constant tone at 1000 Hz like previous version.
