SIZE

SIZE of bit field

Classification: Direct processor control

Command Syntax: SIZE <size>

Limits: <size>

-32 to -1 or 1 to 32 bits Query Syntax: SIZE?

Query Response: <size>

Description: The SIZE command sets the field size (in base 10) used in connection with the GETA, GETR, PUTA, and PUTR commands. If a negative size is specified, then values given (or returned) are sign extended to 32 bits. For example, if SIZE = -16 and a 16 bit field containing FFFF hex is fetched, then the value

FFFFFFFFhex is returned. The SIZE? query returns the current setting of SIZE in base 10. SIZE is preset to 16 each time the generator is powered on.

Note – This command will normally be used only with custom applications and command files created by Quantum Data.

Other Required Cmds:

None

Example:

SMOD

Sequence operating MODe

Classification:

Sequence parameter setting

Command Syntax:

SMOD

Limits:

<mode>

 

0 = Disable

 

1 = Enable manual step mode that stops at last step

 

2 = Enable manual step mode that wraps to first step

 

after last step

 

3 = Enable continuous auto stepping

Query Syntax:

SMOD?

Query Response:

<mode>

Description:

The SMOD command sets the sequence mode. The SMOD? query

 

returns the current setting of SMOD.

Other Required Cmds:

The SEQL command loads the sequence and SEQU starts to run

 

it.

Example:
