Regarding Siglent and Rigol--I'd rather not buy something from a Chicom company.
And yet you plan to stick with western corporate brands that send their production to Asia so to maximize profits.
What other options do I have?
Put your engineers hat on and study datasheets and realize what you get for the spend. < Me 10+ years ago.
Sure, I’d prefer to buy U.S. made test equipment, but, as you say, most western corporate brands build their stuff in China.
That I did not say when in fact I said Asia and if you imagine everyone in Asia is Chinese you'll piss off of lot of Asians.
If you must buy Yank with your budget then it's overdue you pony up with your AWG must have specs so to properly utilize the members knowledge here on the forum.
You could also consider BK Precision or LeCroy however an AWG from them might just be a Siglent but more expensive than from the OEM.
Sal Ammoniac, are there better than Siglent bang for buck, probably but in nearly 9 years of dealing with them their stuff has been very reliable and they've totally stood behind their products in our experience.
Good luck with your hunt.
Here are my must-have specs for a function generator:
Max Frequency: 25 MHz
# Channels: 1 (2 would be nice, but not an absolute requirement)
Built-in Waveforms: Sine, Square, Triangle, Ramp, Pulse, Sinc, Gaussian Noise
Arbitrary: at least 1 MSa, 4-16 MSa
Modes: Frequency Sweep, Continuous
Modulation: AM, FM, PWM (others would be nice, but not an absolute requirement)
Amplitude: 1mV - 10V PP into 50 ohms
Sine Harmonic Output: in the -40 to -50 dBc range
Sine THD: <0.1%
Phase Noise: at least -125 dBc/Hz at 10 kHz
Rise/Fall Time (square & pulse): 10 ns - 1 us variable
Jitter: < 1 ns
I don't have anything against Asians in general, but I'd rather not support the CCP if I can avoid it.
