The time sequences in relay triggering can be described according to the following
brief overview (for more details, refer to the data sheet):
Figure 5-46: Relay trigger timing overview
t = Time axis (logarithmic)
V = Voltage level (trigger control signal, output of switched relay)
A = External
SCPI
trigger command or Manual Trigger in the "WebGUI" (in both cases via Ethernet LAN)
B = External trigger or Manual Trigger in the touch display (here: Trigger Slope = "Positive" or "Any")
C = Output level of digital outputs and solid-state relays (SSR)
D = Output level of electromechanical relays
t
TS1
= Trigger switching time for SSRs (a few microseconds)
t
TS2
= Trigger switching time for electromechanical relays (approximately 10 ms to 15 ms)
t
LANS1
= LAN switching time for SSRs (a few milliseconds)
t
LANS2
= LAN switching time for electromechanical relays (> 10 ms to 15 ms)
As a prerequisite for using a trigger, you must have defined a sufficient number of trig-
gerable paths . A path is triggerable, if all involved modules are triggerable (see Module
Information dialog). Triggerable paths can include (one or combinations of) relays and
digital output ports in many modules, especially if you use a Interconnection setup. The
required number of paths (up to 16) depends on the selected trigger type .
In Interconnection operation , the trigger functionality requires connecting the trigger
signal line also to all secondary switch units, which are involved in the triggered paths,
see
Figure 5-49 .
The trigger dialog consists of the following three sections:

└ Toggle A-B .................................................................................................... 206
└ Sequenced ....................................................................................................207
└ Addressed .....................................................................................................207

Trigger Activation
Trigger activity is indicated by the status LEDs next to the BNC connectors (labeled 1
and 2 in
Figure 5-44 ). The LEDs have the following meanings:
●
Trigger deactivated: both LEDs are off
