Power Switch Options (AMXR)
#Switch Types
Selectable for each switch channel separately
Standard
Dual-level switch
- Output Out switches between two voltage levels Vneg and Vpos
- Vneg ≤ Vout ≤ Vpos must be fulfilled at all times (even when the switch is deactivated)
Option T (Trilevel)
Three-level switch
- Output Out switches between three voltage levels Vneg, Vmid, and Vpos
- Vneg ≤ Vout ≤ Vpos and Vneg ≤ Vmid ≤ Vpos must be fulfilled at all times (even when the switch is deactivated)
- For applications such as injection, compression and ejection of ions
#Isolation
Selectable for each switch channel separately
Standard
- Maximum isolation voltage: 2.1 kV
- Maximum burst frequency: > 10 MHz
- Minimum pulse duration: < 50 ns
- Propagation delay: 65 ns
- Jitter: < 1 ns
Option H (HV Isolation)
High-voltage isolation
- Maximum isolation voltage: 3 kV (5 kV or more upon request)
- Maximum burst frequency: 2 MHz
