The following table describes the test parameters and their settings (gray = N/A).
10. Select Source device by pressing the adjacent soft key on the front panel to specify
that the device under test is a source.
Alternatively, you can specify the device under test as a source using the following
commands:
CPTX:DUTT 1 // specifies the device under test as a source.
You can query the current value of the parameter with:
CPTX:DUTT? // returns the device under test type.
Parameter Explanation
CTS Version Specifies whether you wish to test to the HDCP CTS 1.1
or HDCP CTS 1.2. Please note you will not be able to
select CTS 1.2 if the HDCP CTS 1.2 option is not
