TRACe:DELete:ALL

34980A

TRACe:DELete:ALL

Syntax

TRACe:DELete:ALL {(@<channel>)|<slot>}

Description

This command deletes all trace waveform from volatile memory. Deleting a trace also frees up space in memory previously allocated for the trace waveform.

Used With:

  • 34950A Digital I/O Module (digital output channels only)

  • 34951A Isolated DAC Module

Parameters

Name

Type

Range of Values

Default Value

<channel> 34950A Only

Numeric

One channel in the form (@sccc).

Select from s101 through s104, s201 through s204.

This is a required parameter

<slot>
34951A Only

Discrete

{1|2|3|4|5|6|7|8}

This is a required parameter

Remarks

  • Any channels that were associated with the deleted trace name will lose that association.

  • As traces are deleted, there may be non-contiguous blocks of memory. Use the TRACe:FREE? command to determine the largest contiguous block of memory available.

  • For the 34950A, if you change the width of a bank (see CONFigure:DIGital:WIDTh command), all traces in memory are cleared.

  • For the 34950A, this command does not delete the built-in trace patterns (count-up pattern or "walking ones" pattern).

  • For the 34950A, you cannot delete a trace while buffered memory is enabled. If necessary, use the [SENSe:]DIGital:MEMory:ENABle command to disable memory and then delete the trace.

  • For the 34951A, this command does not delete any of the built-in trace waveforms (Sine, Square, Ramp, etc).

  • For the 34951A, you cannot delete a trace that is currently being output on the specified slot. If you attempt to delete an active trace, an error will be generated. If necessary, use the SOURce:FUNCtion:ENABle command to turn off the trace so it can be deleted.

  • To delete a specific trace name, use the TRACe:DELete[:NAME] command.

  • A Factory Reset (*RST command), Instrument Preset (SYSTem:PRESet command), and Card Reset (SYSTem:CPON command) deletes the trace waveform from memory and removes all trace name associations. In addition, storing the instrument state (*SAV command) will delete the trace waveform from memory and remove all trace name associations.

Examples

The following command deletes all traces stored on channel 101 the 34950A in slot 3.  

TRAC:DEL:ALL (@3101)

The following command deletes all traces stored on the 34951A in slot 4.  

TRAC:DEL:ALL 4
