Automated Performance Tests

LD MATCH XX

Measures reflection at port XX when the port is switched to

 

the test set’s TRANSMISSION port, which is terminated

 

with a precision load. Tests the specified performance of

 

“Load Match, Test Port Selected,” listed in Table 8-2in

 

Chapter 8, “Specifications.”

 

 

 

Steps:

 

•Set specified frequency for test set.

 

•Perform reflection 1-port (User 1-port1) calibration at end

 

of cable (using short, open, and load).

 

•Connect precision load to test set’s TRANSMISSION port.

 

•Measure reflection (S 1) at each port XX connected to test

 

11

 

set’s TRANSMISSION port.

 

•If spec is 16 dB, trace must be below 16 dB.

IC MATCH R->XX

 

Measures reflection at the test set’s REFLECTION port or

and

TRANSMISSION port when the port is switched to port

IC MATCH T->XX

XX. Port XX is terminated with a precision load. Tests the

 

specified performance of “Interconnect Match,” listed in

 

Table 8-2 in Chapter 8, “Specifications.”

 

 

 

Steps:

 

•Set specified frequency for test set.

 

•Perform reflection 1-port (User 1-port1) calibration at end

 

of cable (using short, open, and load).

 

•Connect test cable to test set’s REFLECTION port or

 

TRANSMISSION port.

 

•Measure reflection (S111) at test set’s REFLECTION port

 

or TRANSMISSION port for each port XX when

 

terminated with a precision load.

 

•If spec is 16 dB, trace must be below 16 dB.
