function of the level.

Syntax

:CALibration:ZERO[:AUTO]<wsp>OFF|ON

|0|1|ONCE

:CALibration:ZERO[:AUTO]?

Response 0 = OFF, 1 = ON

Example

:CALIBRATION:ZERO ONCE

:CALIBRATION:ZERO? -> 1

Explanation • If you send this command with the parameter

“ONCE” when the sweep is stopped, offset

adjustment is performed once. In this case,

ON/OFF of this setting does not change.

• On the AQ6370C/AQ6370D/AQ6373B/

AQ6375B, the operation of this command is

complete at the instant the offset adjustment

starts. Therefore, the AQ6370C/AQ6370D/

AQ6373B/AQ6375B can execute the next

command even while offset adjustment is

being performed. You can use :CALibration:Z

ERO[:AUTO]:STATus? to query the execution

status of the offset adjustment.

• This is a sequential command.

:CALibration:ZERO[:AUTO]:INTerval

Function Sets/queries the time interval for executing the

Auto Offset function for the level.

:CALIBRATION:ZERO:INTERVAL? -> 20

Explanation • When a time is set for this parameter, the auto

offset adjustment is performed at the specified

time interval starting from the moment of

execution.

• This command only valid for the AQ6373/

AQ6373B.

• This is a sequential command.

:CALibration:ZERO[:AUTO]:STATus?
