Hi i need a new arbitrary waveform generator.
I would prefer an Agilent - 33512B but their is the price i dont like.
Is their anybody who tested oder use the AFG-2225.
I know Dave test with the rigol .
thanking you in anticipation
Marc

if Price is more important go for Instek.
if Accuracy is more Important go for Agilent.
if Memory is more Important go for Agilent.
if Jitter is more Important go for Agilent.
if testing low voltage circuits, needs 16-Bit, go for Agilent.
Rigol has 14-Bit, Instek has 10-Bit.
if need more than 30Mhz go for Rigol. Agilent is limited to 30Mhz, True Bandwidth. to see 25Mhz SQR without errors, a 500Mhz Scope is needed, 1GHz preferably.
True Bandwidth is determined by RiseTimes, a faster rise time means true Higher Bandwidth,
for example Agilent has maximum 30Mhz, but a Rise Time of 8.4ns,
but Rigol DG4162 160Mhz also has a <8ns RiseTime, usually a true 150Mhz scope has <2.3ns RiseTimes, at 100MHz has <3.5ns, 350MHz 1ns, 500MHz 700ps, or 0.7ns, that means to see a 40ps Jitter is impossible with a 500MHz scope.
Rigol DG4162 is <8ns, DG4102: <10ns & DG4062: <12ns,
Instek is <25ns,
The only interesting difference is the Sample Rate, Agilent is 250MSa/s, Rigol is 500MSa/s, Instek is 120MSa/s.
would be nice to see with a 1Ghz scope, how does it look a 30Mhz SQR coming from the Agilent 33500B vs. the Rigol DG4162.
Allmost all DDS clocks have 700ps jitter rms, Agilent TrueForm "Modified DDS" has less than <40ps p-p.
Higher Frequency needs less Jitter & Fast RiseTimes to work properly.
