and be very careful, it does not tolerate more than ±2 volts input! it
was originally designed for the CSA 803A and requires a relative
complicated control system, it has a 15 to 18 picoseconds rise time, 50
ohms input, and at least 30dB return loss at 18GHz. If both inputs are
used they are differential.
