:MEASure:AMPLitude:ISIVsbit:BITS?

Deprecated command. For FlexDCA revision A.05.60 and above, use the :MEASure:AMPLitude:ISISymbol:SYMBols? query instead.

Query Syntax

:MEASure:AMPLitude:ISIVsbit:BITS?

Description

Moves the measurement to the top of the table. Displays the measurement if it is not already shown on the table. The query form of the command returns the measured value.

Returns a list of bits for which :MEASure:AMPLitude:ISIVsbit? has returned values. The list is returned as (definite-length block data). Each bit value is a 32-bit integer (4 bytes) returned in LSB (Least Significant Byte) first format. The data block is followed by a linefeed termination character (0A hex).

The ISI vs BIT graph does not need to be displayed before data can be returned from this query.

Amplitude analysis must be turned on before the first interference measurement can be made. Use the :MEASure:AMPLitude:DEFine:ANALysis command.

Requires Jitter Mode with additional Advanced Amplitude Analysis/RIN/Q-Factor license .

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.
