What are the CLK (A) and CLK (B) SMA Clock Ports Used For?

Clock A and Clock B are External Reference Clock inputs, used by the test applications in Port 1 and Port 2, respectively.

The 50 Ohms SMA(f) ports labeled CLK A and CLK B are independent External Clock inputs, used as frequency, phase or timing references by test applications in Port 1 and Port 2, respectively.

On VeEX TX340s, the CLK (A) external clock reference input is used by the application running in Port 1 and CLK (B) is for the application in Port 2 of the same module (built-in modules are separated by a vertical orange line). Note that a TX300s test platform with loaded two TX340sm modules (four test port groups) will have two sets of clock reference inputs (total of four SMA CLK ports), with a pair of CLK ports dedicated to each module.
On the original RXT-6000e and RXT-6200 (1st Gen), the CLK (A) external clock reference input is used by the application running in Port 1 and CLK (B) is for the application in Port 2.
On the RXT-6200+ (2nd Gen), the CLK IN (1) external clock reference input is used by the application running in Port 1 and CLK (2) is for the application in Port 2. This version is easily recognizable because it also has two SMA(f) clock output ports, CLK OUT (1) and CLK OUT (2).
