Remote command:
CALCulate<Chn>:EYE:INPut:BPATtern:TYPE
Length
Length of the bit stream.
For a user defined
the length can be specified in terms of bits, Kibits (2^10
bits), Mibits (2^20 bits), Gibits (2^30 bits).
Remote command:
CALCulate<Chn>:EYE:INPut:LENGth:PRBS
CALCulate<Chn>:EYE:INPut:LENGth:BITS
Load Bit Stream
A user-defined bit stream can be loaded from file and is repeated until the configured
is reached. If no pattern is loaded from file, the default pattern "10" is repeated
instead.
The "Bit Stream Load" dialog allows you to select a suitable "bit stream file".
Access:
"Load Bit Stream" button in
Such a bit stream file must be a 7-bit ASCII compatible text file; the Byte Order Mark
(BOM) that is common with UTF encodings is not allowed. Only the ASCII codes 0x30
(“0”) and 0x31 (“1”) are interpreted, all other codes including whitespace and line end-
ings are ignored.
Remote command:
Symbol Rate
The "Symbol Rate" (= baud rate) defines the number of symbol changes per unit time,
or, equivalently, the symbol period (= 1 / "Symbol Rate").
To convert symbol rate to data rate, multiply the symbol rate with the number of bits per
symbol (2 bits per symbol for NRZ, ..., 4 bits per symbol for PAM-16).
Remote command:
CALCulate<Chn>:EYE:INPut:DRATe
Modulation
Defines the modulation of the generated bit stream (NRZ, PAM-4, PAM-8 or PAM-16).
