MHS-5200A function generator teardown / review / reverse engineering
technogeeky:
I continue in this post...
There are "missing" pictures above, but they were just deleted bad-quality duplicates. Fear not, no parts are missing.
edit: Evidently my rotation settings didn't save. Sigh. I give up.
technogeeky:
Measurements of the newer-style MHS-5200A.
Test Conditions:
* both devices reset to default settings
* connected directly using 50-ohm (verified) BNC to BNC cable
* Rigol 1054z with 1x setting
Test 1:
* Control: 2.100 kHz (a reasonable minimum)
* Variable: 1, 5, 10, 15, 20 Volts
* Measuring: Rise Time, Overshoot, Vpp

Test 2:
* Control: 1 Volt peak-to-peak
* Variable: 40, 50, 60, 70, 80, 90, 100, 170, 180 kHz then 2.0 MHz
* Measuring: Fall time, picture

Test 3:
* Control: 6.0 MHz (the fastest frequency which doesn't totally look like a sine wave)
* Variable: 1, 5, 10, 15, 20 Volts
* Measuring: Rise Time, Vpp, Overshoot

I wish we had the firmware to play with. Also anyone probe the pads on the circuit board? On the side. I like the unit. I just wish it had better performance.
