Using Generator with CS-1 Probe
The Test > CS1 Probe option uses the Quantum Data CS-1 color sensor to measure the chromaticity
and luminance (brightness) of a display. The CS-1 probe connects to the generator’s serial port.
Chromaticity is shown as x,y C.I.E. coordinates and the luminance (Y) can be shown either in units of
foot-Lamberts or nits. The CS-1 needs to be over a fully lit white area of the display for accurate
readings. The Flat_Wht test image is suitable for use with the CS-1
Error codes: 1, 7 - CS-1 not seeing a usable test image.
5, 8 - Generator did not find a CS-1 probe.
2, 3, 6 - Probe malfunctioning.
Testing Audio
Select Test > Audio to independently toggle stereo audio output channels on and off.
On a 701 generator, the left channel is also the monophonic audio source for the modulated RF
output.
Testing HDCP Interfaces
Model 701 video test generators may be equipped with an optional production (private) key for testing
High-bandwidth Digital Content Protection (HDCP) interfaces of DVI receivers that support HDCP. For
more information about HDCP, see http://www.digital-cp.com/.
To output HDCP-encyrpted video content:
1. Connect the DVI connector of the generator with the DVI connector of the device under test.
