Pin Signal Name Reference Description (continued)
38 START TRIG* DIGGND External Trigger – In posttrigger data acquisition
sequences, a low-to-high edge on START TRIG*
initiates the sequence. In pretrigger applications, the
low-to-high edge of START TRIG* initiates
pretrigger conversions while the STOP TRIG signal
initiates the posttrigger sequence.
39 STOP TRIG DIGGND Stop Trigger – In pretrigger data acquisition, the
high-to-low edge of STOP TRIG initiates the
posttrigger sequence.
40 EXTCONV* DIGGND External Convert – A high-to-low edge on
EXTCONV* causes an A/D conversion to occur. If
EXTGATE* or EXTCONV* is low, conversions
are inhibited.
41 SOURCE1 DIGGND SOURCE1 – This pin is from the Am9513A
Counter 1 signal.
42 GATE1 DIGGND GATE1 – This pin is from the Am9513A Counter 1
signal.
43 OUT1 DIGGND OUTPUT1 – This pin is from the Am9513A
Counter 1 signal.
44 SOURCE2 DIGGND SOURCE2 – SOURCE5 – This pin is from the
Am9513A Counter 2 signal.
45 GATE2 DIGGND GATE2 – This pin is from the Am9513A Counter 2
signal.
46 OUT2 DIGGND OUTPUT2 – This pin is from the Am9513A
Counter 2 signal.
47 SOURCE5 DIGGND SOURCE5 – This pin is from the Am9513A
Counter 5 signal.
48 GATE5 DIGGND GATE5 – This pin is from the Am9513A Counter 5
signal.
49 OUT5 DIGGND OUT5 – This pin is from the Am9513A Counter 5
signal.
50 FOUT DIGGND Frequency Output – This pin is from the Am9513A
FOUT signal.
The signals on the connector can be classified as analog input signals, analog output signals, digital
I/O signals, digital power connections, or timing I/O signals. Signal connection guidelines for
each of these groups are given as follows.
