5.2.1 Trig In / Out 2 and Out 1 / Trig Out Connectors
See (1) in Figure 5-2 .
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 monitor-
ing.
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.
