Al, Thanks for the good idea, that would certainly have saved me a bit  of 
work:-), but the switch box inserted in the coax line with the counter input 
 set to high impedance performs the same function, straight through 
connection  with the option to switch in a 50 ohm shunt resistor, and it's quite 
clear that  the frequency shift is virtually instantaneous.

     Set your counter to high impedance. Then install a T connector on the 
 input. Then you can install or remove a 50 ohm terminator on the T while 
 plotting the results. Then you can see how fast the frequency shift is 
 depending on the load.
