SOUR:PULS:ENH?
When linking multiple program messages, separate the message using
semicolons (;).The maximum number of linked messages is 12.If 13 or
more messages are sent, the 13th and subsequent messages are
discarded.
Example:

0;INIT;*WAI
The data format is character string data, numeric data, and binary data.
Character String Data
This is a string of ASCII code.
The following example shows a program message for switching to the
OTDR (Standard) mode from the Top Menu.
Example: INSTrument:SELect OTDR_STD
Numeric Data
This is described in binary numerals.
Example:
SYSTem:LOCK 1
TOPM:UNIT 2
SENSe:LOSS:MODE 5
SENSe:FIB:IOR 1.500000
SENSe:VOFF -10.0
When using binary numbers, input numeric values either as integers or
floating point representation.
Binary Data
The head string starts with a number sign (#) and continues with data
after a numeric value indicating the data length.
The character after the number sign (#) indicates the number of digits in
the data.
The binary data follows the number indicating the data length.
Example:
