3.2.2.1 Trig In / Out 2 and Out 1 / Trig Out connectors
See (1) in Figure 3-4 .
The Out 1 / Trig Out BNC connectors supply an analog signal with a voltage between
0 V and 2.5 V. It can be used to output a voltage that is proportional to the measured
value (e.g. for level regulation) or a digital signal for limit monitoring.
The Trig In / Out 2 BNC connectors can be used either as an external trigger input with
a switchable impedance (10 k
Ω
or 50
Ω
) or as a second analog output.
By default, both connectors are disabled.
