The following connectors are available on all instruments:
●
LAN REMOTE is an RJ-45 connector. Use this connector to integrate the instrument
to a Local Area Network, primarily for remote control purposes.
●
REF IN is a BNC input for an external reference frequency. Use this connector to
synchronize the R&S CMW500 to another device.
●
REF OUT 1 is a BNC output for the internal reference frequency of the R&S CMW500.
Use this connector to synchronize other instruments to the tester.
●
The USB connectors can be used to connect e.g. a keyboard, mouse or other pointing
devices, a printer or an external storage device (USB stick, CD-ROM drive etc.).
●
The USB REMOTE connector can be used for remote control of the instrument.
●
TRIG A and TRIG B are two BNC connectors for external trigger signals.
The following connectors are optional:
●
A LAN SWITCH with two RJ-45 connectors is available as option R&S CMW-B660A
and R&S CMW-B661A. It routes data provided by internal boards to the processor
(e.g. payload provided by signaling units).
●
The BNC connectors SYS SYNC OUT 1, OUT 2, OUT 3 and SYS SYNC IN are
provided with option R&S CMW-S550M. They are used to provide or receive time
information.
●
LAN DAU is an RJ-45 connector. It is provided with the Data Application Unit (DAU),
option R&S CMW-B450A. The DAU is required when testing End-to-End (E2E) IP
data transfer and mandatory when using the instrument for protocol testing (U-plane
tests).
●
An I/Q board is available as option R&S CMW-B510A. It provides four digital con-
nectors (labeled "DIG IQ IN/OUT 1", "DIG IQ OUT 2", "DIG IQ IN/OUT 3", and "DIG
IQ OUT 4") for input and output of digital IQ data plus two bidirectional BNC connec-
tors (labeled "AUX A" and "AUX B") for control, clock and trigger signals.
A second I/Q board is available as option R&S CMW-B520A. It provides the digital
connectors "DIG IQ IN/OUT 5", "DIG IQ OUT 6", "DIG IQ IN/OUT 7", and "DIG IQ
OUT 8" and the BNC connectors "AUX C" and "AUX D".
