4 * tg.c generate WWV or IRIG signals for test
7 * This program can generate audio signals that simulate the WWV/H
10 * intended to test the WWV/H driver (refclock_wwv.c) and the IRIG
26 * over the range 0-255. The signal generator by default uses WWV
36 * warning bit in the WWV/H timecode, so is handy to check for correct
41 * During operation the program displays the WWV/H timecode (9 digits)
45 * left to right. For WWV/H The leap warning L preceeds the first bit.
69 #define WWV 0 /* WWV encoder */
74 #define DATA0 200 /* WWV/H 0 pulse */
75 #define DATA1 500 /* WWV/H 1 pulse */
76 #define PI 800 /* WWV/H PI pulse */
128 * WWV/H format (100-Hz, 9 digits, 1 m frame)
241 int tone = 1000; /* WWV sync frequency */
244 int encode = WWV; /* encoder select */
280 case 'd': /* set DST for summer (WWV/H only) */
292 case 'l': /* set leap warning bit (WWV/H only) */
373 * For WWV/H and default time, carefully set the signal
376 case WWV:
401 * once per minute for WWV/H and once per second for IRIG.
435 if (encode == WWV) {
504 * The WWV/H second consists of 9 BCD digits of width-
507 case WWV:
576 * Generate WWV/H 0 or 1 data pulse.
583 * The WWV data pulse begins with 5 ms of 1000 Hz follwed by a
590 * WWV/H radio clock worked much better.
