I have a questions for owners. At first I am interested in sweep function: does it have proper synchronization signal? I mean one pulse on each sweep. I own fy6800 and sweep relaisation here is horrible! There in square wave on sync output with exact frequency of main output while sweeping - just unusable.
yes it has proper sync, but you need to enable in system, by defalt its off (shared, as/with freq counter input) rise on start and fall in the middle of sweep, but rise sync is ahead of start sweep by about 300ns, see attached (10-60MHz sweep, 1ms 5Vpp)... during non sweep (normal sine output), the sync still produces square wave (with 2-3ns rise/fall time) at several multiples of main sine output. later attached picture (625KHz sync square with 10MHz sine output, 937KHz sync square with 60MHz output) so if anyone need fast rise time, sync can give that, but only up to nearly 1MHz freq.
I also interested about noise performance. Does it have any garbage from power supply on output? And another question: how much exactly does the output voltage correspond to the set voltage? Does it have unwanted DC-biasing?
I saw waveforms what you guys posting here and it looks decent for me. But how it can be sine on 60 MHz with 200 megasamples per second? If I doing correct math its about 3.33(3) points per cycle. But constructing sine cycle by ~3 points sounds ridiculous. Does it work because low pass filter?
see THD/FFT below for 10MHz and 60MHz sine (0dBm). i'm not aware of unwanted DC biasing happening. i can say Vpp shown on AWG screen is tally with signal output (mine have some difference maybe due to diy/china 50 ohm termination not really 50 ohm)
what i like so far... signal is flat from basically DC up to 60MHz (5Vpp max), so we dont have to do mental subtraction when trying to see a DUT respond. what i dont like, drawn arbitrary wave from china SW cant be uploaded to the AWG. i believe i clicked all buttons and can guess where the "upload" button is, but once dialog box popped up, we can select arb wave file, but one last button (i believe "upload to device") is disabled
communication with device shown in text box as XXXXX:0 (X = rectangle box) maybe this AWG is not ready to receive arb data from PC? or FW is not completed yet?
and to note, at 5V power input it uses 1A current, so 1000mah battery can last only an hour.
