It also supports arbitrary waveforms uploaded from a computer. Never tried that, either, so I'm not sure what software is available and if it's any good.
Keithley 2400 broken as does not power on.Will you share some details on the fix here? Would be interested in reading that!
So hopefully it is a simple fix.
Will arrive next week

Apologies, waking up an old post...
Can anybody help translate MicSig's specified Accuracy, identical language for CP2100A & B. It's entitled "DC accuracy" but then uses "Apk" which I assume means "Amperes Peak", which wouldn't be DC.
DC accuracy (typical)
3%±50mA (10A) {I'm guessing this line is DC, on 10A range, but no equivalent for 100A range}
4%±50mA(100A,500mA~40Apk) {maybe AC accuracy if Amps peak is <40Amps, up to bandwidth limit .8 or 2Mhz}
15%(100A,40Apk~100Apk) {maybe AC accuracy if Amps peak is >40Amps, up to BW .8 or 2Mhz. saturation of steel core?? so reads lower than reality}
While UTG932E output frequency is limited by 30 MHz, it is possible to get a sinusoidal wave with significantly higher frequency using Arbitrary waveform defined to contain 10 sinus periods. When using such ARB waveform the actual output frequency is 10 times higher than the frequency shown on the UTG932E screen. Unfortunately, in this case frequency-dependent amplitude correction is not applied by UTG932E, so the amplitude shown by 1 second 10MHz to 80 MHz sweep is lower than it would be in non-Arb modeInteresting way to obtain higher frequency output.
At the turn-on moment the power supply current has short spikes exceeding 6A, then for about 8 ms the current is between 4A and 3.2ACurrent peaks are from inrush current to input caps of SMPS. It is not that bad, there much worse cases where switches fail in time (weld themselves) due to uncontrolled high inrush current.
...
Only after that current drops to normal 1A. Such high current glitches explain why it was not possible to power UTG932E by power bank with 2.4A rated output.
