SAT measurement

SAT Analogue Sound Carrier Frequency

Each video signal has several sound carrier frequencies assigned to it. Selective hearing of the sound maincarriers and the sound subcarriers is possible. The sound carrier frequency is tunable from 5.0 MHz to 8.99 MHz in 10 kHz steps. The soundcarrier bandwidth is automatically changed over from wide (280 kHz) to narrow (150 kHz) at 7.00 MHz.

The following sound carrier frequencies are factory-set:

key	Frequency in MHz	Bandwidth in kHz
[1]	5.80	280	wide
[2]	6.50	280	wide
[3]	6.65	280	wide
[4]	7.02	150	narrow
[5]	7.20	150	narrow
[6]	7.38	150	narrow
[7]	7.56	150	narrow
[8]	7.74	150	narrow
[9]	7.92	150	narrow

✐

Retrieving sound carrier 7.38 MHz:

Press [2ndF] [SC] [6]

LC display:

SC: 7,38MHz	SAT
BW:NARROW
Note

•Sound subcarrier: 7.38 MHz

•Sound carrier bandwidth: narrow = 150 kHz

•Mode: SAT

After SAT mode has been called up, the MSK 25 will be permanently ☞ adjusted to sound carrier 7.02 MHz. Frequency variations of the sound

carrier will not be retained after SAT mode has been closed.
