Function generator with simultaneous modulations

(1/5) > >>

maxwell3e10:
I am looking for a function generator that can simultaneously be controlled by burst count and external amplitude modulation. It seems most of them allow only one at a time but this is poorly documented.  DS345 from Stanford research systems can do it, but its pretty old and only allows 30000 burst counts, while I need 10^6, as most modern ones do. Any suggestions? Perhaps someone has used this mode or would be willing to test theirs.

capt bullshot:
Just a quick test result:
On the Agilent 33522B modulation and burst is exclusive, activation of either one turns off the other one

kultakala:
I assume it will blow your budget...  but while looking at some oscilloscopes and function generators on the Rohde & Schwarz site i stumbled over the HMF2525.
Its about 1700 $  ::)

But in the manual it says:

- AM modulation: Only one type of modulation may be active at any time.
- Burst mode: The BURST mode is available for each waveform, also for any symmetry setting.

In the german version its says even more clear that burst mode works for any kind of signal.

So it seems that this puppy could do it, but maybe i am misinterpreting it ?

maxwell3e10:
Perhaps it would work. At least logically those two functions shouldn't interfere. One small problem is that it says that the burst mode is limited to 50,000 cycles. But it has a synchronous gated mode, which I think might have similar functionality.

tautech:
A bit of a fiddle with a SDG1062X gets this:



Ch 1, REF=Internal, 50 KHz Sinewave @ 5V p-p, Burst 50 KHz, 1 cycle (50 us). Start Phase=270o

Into: Aux In/Out

Ch 2, 1 MHz Sinewave @ 1V, MOD AM, Source=External..............to scope.
