Subject: [time-nuts] Identifying Picosecond Pulse Labs Part?
I have acquire some Picosecond Pulse Lab parts, about 2 in long with SMAs at
either end. They were advertized as DC block/2 GHz low pass filter.
However
a) It isn't a DC block - DC resistance from input to output is < 1 ohm.
b) It isn't a low pass filter - S12 is quite flat at 0 dB from 0 to 20 GHz.
Also, DC resistance from input or output to ground is infinite.
The only identification on it is "Picosecond Pulse Labs 9008". Any thoughts
as to what these things are?
Thanks!
Jim
