DSP

Syntax

DSP <Hz> or DSP ON or DSP OFF

Description

Controls the digital offset-removal filter (a digital high-pass).

• DSP <Hz> sets its cut-off. The filter works in discrete steps that depend on the sampling rate; the reply tells which cut-off was applied.
• DSP ON / DSP OFF enable or bypass the filter without changing its cut-off.

SETUP must have been done, and acquisition must be stopped. The settings are kept by the board and re-applied by every later SETUP.

Parameters

Parameter	Type	Description
<Hz>	number > 0	Requested cut-off frequency.
ON / OFF	keyword	Enable or bypass the filter.

Response

OK DSP request=<Hz> applied=<Hz>
OK DSP dsp=ON
OK DSP dsp=OFF

Errors

Reply	Condition
ERR DSP not_setup	SETUP has not been done.
ERR DSP running	Acquisition is running.
ERR DSP busy	Another operation is in progress.
ERR DSP bad_arg	Missing or invalid value.
