Abstract
A reflectometer for allowing a test of a device, the reflectometer comprising: a source of pulsed radiation; a first photoconductive element configured to output a pulse in response to irradiation from the pulsed source; a second photoconductive element configured to receive a pulse; and a transmission line arrangement configured to direct the pulse from the first photoconductive element to the device under test and to direct the pulse reflected from the device under test to the second photoconductive element. At least one of the first and second photoconductive elements is provided on a different substrate to that of the transmission line arrangement.

A reflectometer for allowing a test of a device, the reflectometer comprising:
- a source of pulsed radiation;
- a first photoconductive element configured to output a pulse in response to irradiation from said pulsed source;
- a second photoconductive element configured to receive a pulse;
- and
- a transmission line arrangement configured to direct the pulse from the first photoconductive element to the device under test and to direct the pulse reflected from the device under test to the second photoconductive element;
- wherein at least one of said first and second photoconductive elements is provided on a different substrate to that of the transmission line arrangement.
A method of performing a reflectometry test on a device, the method comprising:
- providing a source of pulsed radiation;
- providing a first photoconductive element configured to output a pulse in response to irradiation from said pulsed source;
- providing a second photoconductive element configured to receive a pulse;
- and
- directing the pulse from the first photoconductive element to a device under test and directing the pulse reflected from the device under test to the second photoconductive element using a transmission line;
- wherein at least one of said first and second photoconductive elements is provided on a different substrate to that of the transmission line arrangement.
