LOW VOLTAGE RevB FULL TEST

Overview: For this test the voltage input of the Filament Supply RevB was connected to the output of the LV Mixer RevB. In this test the LV Mixer was tested at an operating Frequency of 1MHz.

Measurements: The same system for measurements on the filament supply was used as ​Filament Supply RevA 2/7/20.

Results:
LV Mixer RevB output: hv pics, insert lv pics

In the two images above, both the rise and fall time of the output from the HV Pulser is ~100ns. It is also worth nothing the absence of over and undershoot. The major modification made to the HV Pulser in RevB was adding a diode clamping circuit to the output. This appears to be working properly and preventing the output from over/undershooting as it switches from ground to the supply voltage.
Filament Current Supply RevB output:

In these two images you can see the linear behavior of the Filament Current supply. In the first image there is essentially no voltage gap between the top and bottom of the load, in this state no current is being pushed through the load. In the second image there is a 10V drop across the load. For this test the load was a 10W 10ohm cement resistor. As expected the voltage drop across the load scaled linearly between these two images as the potentiometer was adjusted. The full behavior of the Filament supply is described in more detail in ​this page

These two images show the fall and rise behavior of the Filament Current Supply. The Filament Current Supply also has a rise and fall time of ~100ns, this means it doesn't add any delay to the output of the HV Pulser. In these two images it is also visible that there is no relevant delay between the top of the load (the output of the HV Pulser) and the Filament Supply response in the bottom of the load.
Results: These results are good. RevB of the HV Pulser and Filament Supply are both working properly.
Special Note on Noise: From the above images there is visible noise.
