20250305 SPS Transfer Function Data (New scope and pulse generator)

Raw data from the SPS cable transfer functions. Transfer functions were measured from after the hybrid combiner to the oscilloscope in the SPS Faraday cage in BA3. The oscilloscope used to measure the data published here is a new scope (Tektronix MSO66B 6 series) which will be replacing the previous MD scope (Tektronix DPO 7254C).

These measurements were taken with a new pulse generator (Active Technologies Pulse Rider PG-1072) which can produce pulses with a width of 300 ps, allowing us to probe higher frequencies in the transfer function. Previous measurements were taken with the Picosecond Pulse Labs Impulse Generator which produced pulses with a width or around 1 ns.

Note that files labelled 'Output' refer to the MD scope line.
