QPHY-MOST150O VARIABLES
Default Bitrate
Specifies whether the bitrate is based on 48 kHz or 44.1 kHz frames.
Fixed Bitrate Mode
Specifies whether the fixed bitrate defined above is used instead of the measured value.
Pre-measured Dark Level
The dark level value can be entered if it is already known.
Debug Mode
When active, the test will pause after each test for debugging purposes and displays the parameter
values.
Demo Mode
Specifies whether to use saved waveform data for testing or captured live signals.
Clock Recovery Edge
Specifies the clock edge use for Eye diagrams. Positive is the default and is required for compliance.
MOST Root Function
Specifies the math function to be used for the tests. Where additional function channels are required they
are allocated consecutively from the set value. A minimum of 3 function channels are required.
Absolute Eye Masks Size
Specifies whether the scaling of absolute eye diagrams is determined by the eye mask or the waveform
amplitude.
MOST Minus Signal Input
Specifies the input channel for the negative signal when using a single ended probe or direct connections
(SMA cables). Set to 'None' for compliance testing using a differential probe.
MOST Optical Signal Input
Specifies the input channel for the O/E converter. If no O/E converter is being used set to ‘None’.
MOST Plus Input
Specifies the differential probe channel or the input channel for the positive signal when using direct
connections (SMA cables).
MOST Parameter
Specifies the first available parameter to be used for the tests. Where additional parameters are required
they are allocated consecutively from the set value. A minimum of 3 parameters are required.
Quick Mode
Specifies if existing channel settings are reused for tests in the same group where possible. This is the
default.
