Minimum gap size to show Gap 1/ Minimum gap size to show Gap 2 ← Gap
Channel Definition
If the gap between the sub blocks does not exceed the specified bandwidth, the gap
channels are not displayed in the diagram. The gap channel results are not calculated
in the result summary.
This command is only available for symmetrical gap channels in "Auto" gap mode (see
Remote command:
[SENSe:]POWer:ACHannel:GAP<gap>[:AUTO]:MSIZe
Number of Lower Gap Channels ← Gap Channel Definition
Defines the number of lower gap channels in the specified gap for asymmetrical (man-
ual) configuration of gap channels.
Remote command:
[SENSe:]POWer:ACHannel:GAP<gap>:MANual:CHANnel:COUNt:LOWer
Number of Upper Gap Channels ← Gap Channel Definition
Defines the number of upper gap channels in the specified gap for asymmetrical (man-
ual) configuration of gap channels.
Remote command:
[SENSe:]POWer:ACHannel:GAP<gap>:MANual:CHANnel:COUNt:UPPer
Gap Channel Spacing ← Gap Channel Definition
Gap channel spacings are normally predefined by the MSR standard but can be
changed.
Gap channels are defined using bandwidths and spacings, relative to the outer edges
of the surrounding sub blocks.
The required spacing can be determined according to the following formula (indicated
for lower channels):
Spacing = [CF of gap channel] - [left sub block CF] + ([RF
