transistor state in Vpulse source

Hello,  i am simulation a mixer with LO vpulse and RF with sinus source,

The mixer output spectrum works fine as shown bellow,but when i look and the BIAS state of LO transistor it shows me that  its in cutoff region as shown in the table in the end.

i understand the the LO source needs to switch the transistor from cuttoff to saturation, is there a way i can see the states in which the transistors switches?(i am not sure it goes to region 2)

Thanks
