[:SOURce<hw>]:BB:DVBC:USEFul[:RATE]:MAX?
Queries the maximum data rate, that is derived from the current modulation parameter
settings.
The value is the optimal value at the TS input interface, that is necessary for the modu-
lator.
Return values:
<InpSigMaxRate> float
Range:
0 to 999999999
Increment: 0.000001
*RST:
0
Example: See Example "Configuring general input signal properties"
on page 46.
Usage: Query only
Manual operation: See " Max. Useful Data Rate" on page 15
[:SOURce<hw>]:BB:DVBC[:INPut]:DATarate?
Queries the measured value of the data rate of one of the following:
External transport stream including null packets input at "User 1" connector
External transport stream including null packets input at "IP Data/LAN" connector
(TSoverIP)
The value equals the sum of useful data rate r
meas
and the rate of null packets r
0
:
r
meas
=
r
meas
+ r
0
Return values:
<InpSigDatarate> float
Range:
0 to 999999999
Increment: 0.001

[:SOURce<hw>]:BB:DVBC:USEFul[:RATE]?
Queries the data rate of useful data r
useful
of the external transport stream. The data
rate is measured at the input of the installed input interface.
