Agilent Technologies B2201A manual Sre, Parameter Explanation

SCPI Command Reference *SRE

*SRE

This command sets the Service Request “Enable” Register bits. 1 enables, 0 masks.

Syntax *SRE enable_number

Parameter	Explanation
enable_number	decimal integer (that is the sum of the binary-weighted values
	for the desired bits), hexadecimal, octal, or binary value

Query response enable_number <newline><^END>

Semantics The Service Request “Enable” Register consists of 8 bits: Bit0 to Bit7. Bit6 is not defined, and is always 0. The Service Request “Enable” Register determines which bits of the Status Byte Register are enabled.

The status of the enabled bits are ORed together, and the result of OR is output to bit6 (Master Summary Status bit) of Status Byte Register. For details, see “Status Reporting Structure” on page 5-53.

The following table shows the bits of the Status Byte Register, and the binary-weighted decimal value of each bit.

bit	binary-weight	description
0	1	not used
1	2	not used
2	4	not used
3	8	not used
4	16	MAV (Message Available summary-message)
5	32	ESB (Event Status Bit)
6	64	MSS (Master Summary Status)
7	128	not used

Example	The following four lines enable the same bits (bit 4 and 5):
	OUTPUT @Agb2200;"*SRE 48"		using decimal numeric
	OUTPUT @Agb2200;"*SRE #B110000"		using binary numeric
	OUTPUT @Agb2200;"*SRE #Q60"		using octal numeric
	OUTPUT @Agb2200;"*SRE #H30"		using hexadecimal numeric
