LEVEL specifies the setting of the attenuators in the base band converters (BBCs). Values between -1 and 256 can be used. If -1 is set, the autoleveling will be activated. If 256 is set, the value from the previous scan will be used, thereby locking in an autolevel value for, for example, pointing. Any value in between sets a specific attenuation, but such values are rarely used. Only one value is accepted but SCHED writes that value out separately for each baseband channel.
