#Switch Types

Selectable for each switch channel separately

Standard

Dual-level switch

Output
In older devices: output ComOut
(in older devices: output Com)
switches between two voltage levels V_neg and V_pos
V_neg ≤ V_out ≤ V_pos must be fulfilled at all times (even when the switch is deactivated)

Option T (Trilevel)

Three-level switch

Output
In older devices: output ComOut
(in older devices: output Com)
switches between three voltage levels V_neg, V_mid, and V_pos
V_neg ≤ V_out ≤ V_pos and V_neg ≤ V_mid ≤ V_pos must be fulfilled at all times (even when the switch is deactivated)
Allows for field-free phases in digital ion traps (DITs)
Undisturbed injection or extraction of charged particles
