This parameter sets the active edge of the symbol clock, as configured with the param-
eter Clock Input Slope.
To set the active edge of the bit clock, use the parameter Bit Clock Slope.
Observe the impact of this parameter on the preview graphic.
See also "External Modulation Data" on page 229.
Remote command:
[:SOURce]:INPut:USER:CLOCk:SLOPe on page 862
Bit Clock Slope ← Settings for Data Source = External
Sets the active edge of the bit clock.
Timing deviations between the clock and the data signals, that are smaller than ± 1/16
of the clock period, are:
●
Automatically corrected
●
Indicated with the parameter Clock to Data Time Deviation
Observe the impact of this parameter on the preview graphic.
Remote command:
[:SOURce<hw>]:BB:DM:SMODulation:CLOCk:SLOPe:BIT on page 896
Bit Order ← Settings for Data Source = External
Sets the bit order, LSB or MSB first, used to process the externally supplied higher bit
modulation serial data.
Remote command:
[:SOURce<hw>]:BB:DM:SMODulation:BORDer on page 895
Clock to Data Time Deviation ← Settings for Data Source = External
Indicates timing deviations between the clock and the data signals. Timing deviations
that are smaller than ± 1/16 of the clock period are automatically corrected.
See also "External Modulation Data" on page 229.
Remote command:
[:SOURce<hw>]:BB:DM:SMODulation:CDTDeviation on page 896
Throughput Delay ← Settings for Data Source = External
Indicates the time delay between the active clock edge for the extern data and the cen-
ter of the modulation symbol (associated with this data item) on the RF connectors,
see Figure 4-13.
