JTAG Probes for ARM
ADA-JET-ARM20 and ADA-JET-ARM14
Signum JTAG probes for ARM provide a physical interface between Signum emulators for the ARM processor
and ARM target boards. These probes have 20-pin (ADA-JET-ARM20) and 14-pin (ADA-JET-ARM14)
double-row, polarized, .100" × .100". (2.54 mm × 2.54 mm) female connectors. Signum JTAG probes come
with a 30.5 cm (12 in.) cable. The layout and dimensions of the probes are shown in
