• "SMC_2P" (Response + Input + Output)  All four sweeps required. Most accurate.

Note: The “SMC_2P” is the only correction type that automatically forces the reverse measurements (SC12, RevOPwr, RevIPwr). If you require any of the reverse measurements while using a lesser correction type, either include those parameters in your channel or use the SENSe:MIXer:REVerse command. Keep in mind that adding the reverse measurements or forcing the reverse sweep using the SENSe:MIXer:REVerse command will increase the number of sweeps required in the channel.

<cnum>

Channel number of the measurement. There must be a selected measurement on that channel. If unspecified, <cnum> is set to 1.

<num>
