Explanation of Options (AMXT)

This overview describes the options denoted by additional letters in the names of our switches.
If you wish to add any of these options to a device, do not hesitate to contact us or configure a custom switch.

#Switch Types

Selectable for each switch channel separately

Standard

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)

Option T (Trilevel)

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

#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
Propagation delay: 120 ns

#Power Supply

Modification of entire device

Standard

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

Option N (Low Noise)

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

#Additional Features

Modification of entire device

Option E (Enable)

TTL input for enabling or disabling all switches

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

Option F (Fan)

Fan for active cooling of the switches

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