Comments • <count_preset> if included, allows presetting the absolute counter associated with the channel pair. All quadrature pairs in <ch_list> will be preset to the same value. If not included, the default count at algorithm start will be zero.
•<ch_list> must always specify both channels of a pair. More than one pair can be specified. Both channels of any pair must be adjacent. <ch_list> can specify channels on more than one E1538. The channel numbers in <ch_list> must be in ascending order. The related error messages are:
3115, "Channels specified are not in ascending order."
3116, "Multiple channels specified are not grouped correctly." 3117, "Grouped channels are not adjacent."
3122, "This multiple channel function must not span multiple SCPs."
•The algorithm reads the current count through the low numbered channel. The count is an unsigned
•*RST Condition: SENS:FUNC:COND and INP:POL NORM for all digital SCP channels.

Usage See “Sense Quadrature Position” on page 21.
SENS:FUNC:QUAD 8192,(@142,143)
pair 42&43 will return quad count (on ch 142), count preset to 8192
