Options (AMXT)

Dual-level switch

• Output Out switches between two voltage levels V_neg and V_pos or has a high impedance (also called Hi-Z or Tristate) when the switch is deactivated
• Controlled by one digital signal, polarity selectable
• V_neg ≤ V_out ≤ V_pos must be fulfilled at all times (even when the switch is deactivated)

Three-level switch

• Output Out switches between three voltage levels V_neg, V_mid, and V_pos or has a high impedance (also called Hi-Z or Tristate) when the switch is deactivated
• Controlled by two digital signals, polarities and control logic selectable
• 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)
• For applications such as injection, compression and ejection of ions

• Maximum isolation voltage: 2.1 kV
• Maximum burst frequency: > 10 MHz
• Minimum pulse duration: < 50 ns
• Propagation delay: 65 ns
• Jitter: < 1 ns

High-voltage isolation

• Maximum isolation voltage: 3 kV (5 kV or more upon request)
• Maximum burst frequency: 2 MHz
• Propagation delay: 120 ns

• Nominal operating frequency of the auxiliary switching regulators: 125 kHz
• Optional dithering control

Power supply optimized for low noise level at the switch output

• Shielded transformers
• Nominal operating frequency of the auxiliary switching regulators: about 28 kHz
• Low high-frequency noise due to resonant converters
• Optional dithering control

TTL input for enabling or disabling all switches

• Connector: BNC socket
• Input level: TTL
• Polarity selection: slide switch on the rear panel

Fan for active cooling of the switches

• For operation at higher frequencies and/or loads
• Recommended for switching powers above 1 W
