...Phase/frequency noise at HF !!!
I just received my FY-6600 signal generator.
It works correctly on audio, but as soon as i go into the 100's of kHz, i can see notable unwanted phase modulation on the scope (SSB demod using an Agilent 8935), althrough the modulation remains inaudible on SSB but as soon as i go into the HF spectrun (10-20 MHz), the phase modulation is so intense that it can clearly be heard on SSB. The µHz resolution is simply a farce.
The genarator's precision may be good for some (mine had a +30 PPM error) but for a 14 digit unit (1 µHz resolution), it is unacceptable.
I have bought this generator mainly for it's 14 digit resolution and it's 14 bit DAC but it fails miserabily.
Do NOT be fooled by it's so-called µHz resolution (unless you generate in the milli-Hertz range), it fails miserabily, and at HF on SSB, it becomes totallt unusable.
