I don't think "1205cx" sends a series of pulses.
Nicole Mun wrote on Jan 27th, 2010, 9:09am:and pulse width is adjustable, I may be able to create something closer to 500Mhz.
Even if "1205cx" can send a series of pulses, periodical signal of 500MHz have any meaning in TDR ?
Do you understand TDR correctly ?
Generally you can not measure frequency characteristics of impedance by TDR.
If you want to consider frequency characteristics in TDR, rather control rise time of pulse not period of pulse.

How do you approximate vswr and insertion loss with a TDR ?
Again do you understand TDR correctly ?
