CALCulate<cnum>:GDELay:FREQuency <value>

(Read-Write) Sets group delay aperture using a fixed frequency range. See Critical Note
Parameters
<cnum>	Channel number of the measurement. There must be a selected measurement on that channel. If unspecified, <cnum> is set to 1.
<value>	Frequency range (in Hz) to use for the aperture setting. Choose between the equivalent of two data points and the channel frequency span.
Examples	CALC:GDEL:FREQ 1E6
Query Syntax	CALCulate<cnum>:GDELay:FREQuency?
Return Type	Numeric
Default	Frequency range that equates to 11 points. This can be changed to two points with a preference setting.

CALCulate<cnum>:GDELay:PERCent <value>

(Read-Write) Sets group delay aperture using a percent of the channel frequency span. See Critical Note
Parameters
<cnum>	Channel number of the measurement. There must be a selected measurement on that channel. If unspecified, <cnum> is set to 1.
<value>	Percent of frequency span to use for the aperture setting. Choose between the equivalent of two data points and 100 percent of the channel frequency span.
Examples	'set to 25 percent of the channel frequency span CALC:GDEL:PERC 25
Query Syntax	CALCulate<cnum>:GDELay:PERCent?
Return Type	Numeric
Default	Percent of frequency span that equates to 11 points. This can be changed to two points with a preference setting.

CALCulate<cnum>:GDELay:POINts <value>

(Read-Write) Sets group delay aperture using a fixed number of data points. See Critical Note
Parameters
<cnum>	Channel number of the measurement. There must be a selected measurement on that channel. If unspecified, <cnum> is set to 1.
<value>	Number of data points to use for the aperture setting. Choose between two points and the number of points in the channel.
Examples	'set to 25 data points CALC:GDEL:POIN 25
Query Syntax	CALCulate<cnum>:GDELay:POINts?
Return Type	Numeric
Default	11 points. This can be changed to two points with a preference setting.
