Measured the current draw of the ISS AOM driver.
 - 980 mA at 23.54 V, with the ISS oscillating
 - 483 mA to 503 mA at 24 V, depending on the RF output

    For the FSS, 1-ohm resistors were soldered onto a DB37 breakout and the voltage
across them was measured.  Ideally the resistance would be lower but I didn't know
what current to expect and thought any voltage reading might be too small.
  * +24V, 89.5 mV and 82.5 mV for a total of 172 mA
  * -24V, -81.3 mV and -81.9 mV, for a total of 163.2 mA
