Frequency, level or other various functions can be set with ten key, rotary
encoder or arrow key.

Reference frequency
Highly stable reference frequency source with temperature stability of
<±0.2ppm @ 0 to 50°C and aging rate of <±0.5ppm/year is installed.
Furthermore, "High stability timebase MSG700-03" (option) is ready for
meeting the demands of more stable reference frequency source.
Phase offset function
MSG703 is equipped with the reference frequency input (REF IN) and
output (REF OUT). By using these two terminals and the phase offset
function, the phase of the output signals of two MSG703 can be synchro
-
nized. However, it is necessary that the two units have the same
frequency. Also if the frequency is changed (even if both units are the
same frequency), the phase offset should be set again because the
phase will be shifted.
