SMA Description
FLT Discrete Fault Indicator output. Isolated Open Collector active high output with
internal pull up to +5Vdc. Can be used to signal external devices when a fault
condition is detected.
INH Remote Inhibit. (TTL input)
TRIGGER
OUT1
Trigger Output (TTL output). The Trigger Output (Trig Out1) is an active low TTL signal
with a duration of no less than 400 usec.
(Can be set to Function Strobe for compatibility with CI L Series)
TRIGGER
IN1
Trigger Input (TTL input)
RPV / NA Remote programming voltage. DC voltage input 0 to +10 VDC for 0 to full-scale output
voltage programming.(RPV option)
Table 3-4: SMA Connectors – Lx Series
3.6.3 SMA Connectors – Ls Series
SMA connectors. Functions are called out on rear panel decal. Table 3-5 shows connections
from left to right when standing at the rear of the Ls cabinet. SMA connectors are small high
frequency capable coax connectors that can be screwed down securely to prevent signal loss.
Adaptor for SMA to BNC conversion are readily available.
To connect these signals using more conventional BNC cables, SMA Male to BNC Female
adapters may be used. These are available from
