Command Reference
ALS?
Execution
Conditions
The SPGU operating mode must be set to ALWG with the SIM 1 command.
Syntax ALS chnum,bytes
block
Parameters chnum : SPGU channel number. Integer expression. 1 to 10 or 101 to 1002. See
Table 4-1.
bytes : Total number of bytes of the ALWG sequence data. Numeric
expression.
block : ALWG sequence data (binary format, big endian).
ALS?
This query command returns the ALWG sequence data of the specified SPGU
channel.
Syntax ALS? chnum
Parameters chnum : SPGU channel number. Integer expression. 1 to 10 or 101 to 1002. See
Table 4-1.
Query Response block<^EOI>
Returns the ALWG sequence data (binary format, big endian).
ALW
This command sets the ALWG pattern data.
To generate an arbitrary linear waveform, the SPGU channels need both sequence
data and pattern data. The sequence data must be used by and in common with all
SPGU channels installed in the B1500. And the pattern data must be set to each
SPGU channel.
See “SPGU Module” on page 2-53 for details on the ALWG output and the data
format.
Execution
Conditions
The SPGU operating mode must be set to ALWG with the SIM 1 command.
Syntax ALW chnum,bytes block
