:MEASure:JITTer:EBITs?
Deprecated command. For FlexDCA revision A.05.60 and above, use the :MEASure:JITTer:ESYMbols command instead.
Query Syntax
:MEASure:JITTer:EBITs?
Description
Returns an ordered list of edge bit numbers returned as definite-length block data. Each value is the number of the bit in the pattern preceding the edge transition and is in the range of 0 to pattern length minus 1. Each bit number is a four byte integer. Only the edges of the type specified by the command :MEASure:JITTer:DEFine:EDGE are included in the list. The data block is followed by a terminator character, 0A hex (linefeed). This query will return an incomplete list of edges, if all of the data needed to determine the pattern has not yet been acquired. Use the :MEASure:JITTer:DDJVsbit? query to return the DDJ values. Use the :MEASure:JITTer:PATTern? query to return the edge type values.
This query produces an error if jitter signal type is set to clock signal (:MEASure:JITTer:DEFine:SIGNal CLOCk).
Requires option 200 (Enhanced Jitter Analysis). For PAM4 signals requires additional option 9TP (PAM-N Analysis).
Endiannes of Returned Data
To specify the byte order (endiannes) of the binary data, use the :SYSTem:BORDer command. The factory preset setting is little-endian in which the LSB (Least Significant Byte) is sent first. Because an incorrect endianess setting can be frustrating to troubleshoot, if you share your 86100D with other people, it is a good idea to explicitly set the endianess before transferring binary data and to restore FlexDCA's endianess setting upon completion of of your program. Use the following sequence of commands:
endian_setting = :SYSTem:BORDer? :SYSTem:BORDer BENDian … … :WAVeform:XYFormat:FLOat:YDATa? … … :SYSTem:BORDer endian_setting
Be aware that VXI plug-and-play drivers can change the endianess setting. As a result always explicitly set the endianess in your program before transferring any binary data.
