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.

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 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.
