Figure 3–32: Serial STATUS display for firmware V1.X
The V1.X firmware Status screen includes cable measurement features. With
V2.X firmware, these features moved to the DISPLAY CABLE screen. The
V1.X features provide the following information:
H CABLE TYPE. Select the type of cable connecting the video source to the
waveform monitor. The correct Cable Type is necessary to calculate the
Serial Signal Level and Cable Length.
H SERIAL SIGNAL LEVEL. Indicates the amplitude of the signal source
relative to the 800 mV standard. The value 0 dB indicates a good 800 mV
signal. A value of –3 dB would indicate a source with 0.707 of the expected
amplitude. To get an accurate measurement, you must select the correct
CABLE TYPE for your installation.
H APPROXIMATE CABLE LENGTH. Indicates the length of the cable
between the signal source and the waveform monitor. The waveform monitor
calculates the cable length based on the signal power at the input. To get an
accurate measurement, you must select the correct CABLE TYPE for your
installation.
