Measurement / Topology
"Measurement" allows you to select an S-Parameter, i.e. the transmission (or reflec-
tion) whose time domain properties shall be analyzed. The "Topology" to the right is
updated accordingly.
Remote command:
CALCulate<Ch>:PARameter:MEASure
Bit Stream
Describes the bit stream generated by the "virtual" generator.
"Bit Stream" can either be a pseudo-random binary sequence (PRBS) of the selected
Length or a user defined bit stream.
The PRBSs are generated using a linear feedback shift register with generator polyno-
mials allowing the maximal run length of the sequence.
Remote command:
CALCulate<Chn>:EYE:INPut:BPATtern:TYPE
Length
Length of the bit stream.
For a user defined Bit Stream the length can be specified in terms of bits, Kibits (2^10
bits), Mibits (2^20 bits), Gibits (2^30 bits)
Remote command:
