Mod accumulator
Another source for the synchronization outputs can be the MSB of the
phase accumulator on the modulation generator. As with the main phase
accumulator, the switching threshold is located at 0 degrees and 180
degrees. Since there is only one modulation generator, only one
synchronization signal can be generated. The signal at the
synchronization output is a squarewave signal with a fixed duty cycle of
1:1.
Trigger
The synchronization outputs can be set so that the trigger signal ( 6-
157) is fed to one or both of the synchronization outputs. The value set
for trigger delay does not delay the synchronization signal relative to the
trigger signal.
Frequency marker
The Sweep menu can be used to set a frequency marker ( 6-152). If a
frequency sweep is to be carried out at the position of the frequency
marker, a synchronization signal is generated. The synchronization
output is "high" as long as the currently applicable frequency is higher
than the set marker frequency.
Waveform marker
When creating an arbitrary function (with the aid of PC software) a
marker can be inserted at any point. If the
Arbitrary
waveform is
generated in the R&S AM300 at the position of the waveform marker, a
synchronization signal is generated. The synchronization output is "high"
as long as the currently applicable frequency is higher than the set
waveform frequency.
