Automated Performance Tests

SRC MATCH XX

Measures reflection at port XX when the port is switched to

 

the test set’s REFLECTION port, which is terminated with

 

a precision load. Tests the specified performance of “Source

 

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 precision load to test set’s REFLECTION port.

 

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

 

11

 

set’s REFLECTION port.

 

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

LD MATCH INT XX

 

Measures reflection at port XX when the port is terminated

 

with the internal load (port XX is not switched to either the

 

test set’s REFLECTION port or TRANSMISSION port).

 

Tests the specified performance of “Load Match, Test Port

 

Unselected,” 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).

 

•Measure reflection (S111) at each port XX when not

 

connected to test set’s REFLECTION port or

 

TRANSMISSION port.

 

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