We have an AOM power amplifier application where [Booster](https://github.com/sinara-hw/Booster/wiki) appears overkill (manufacturing/mechanics, complexity, number of channels, output power, bandwidth…

Problem:
Output level instability, probably caused by insufficient PA drive.
Fix:
- Remove C2 (or replace by lower value capacitor, like 220pF).
- Bypass R5 with a 100nF capacitor to extend ramp…

### What would you like to know?
I received a few 0.5A 72V PPTC components. Does it make sense to connect these to the antenna input as protection against overvoltage and high currents?
I have no…

According to the RINEX 3.04 the antenna reference point (ARP), i.e., a well-defined point on the antenna, e.g., the
center of the bottom surface of the preamplifier. The antenna height is measured fr…

Hi! I have used the toolbox to predict the spike probability of my 2P recordings (jRCaMP1a, 30Hz). On average the noise levels are around 3-4, so I decided to use the 'Global_EXC_30Hz_smoothing50ms_ca…
