Rear Panel Connectors

BASEBAND I/O

Four pins are functional on this connector:

• I channel (pin 9)
• Q channel (pin 26)
• Ground
• Ground

CLK IN

Not functional for this release.

COUNTER IN

Not functional for this release.

DATA IN

Not functional for this release.

DATA VALID IN

Not functional for this release.

EXT INTERFACE CONTROL

Not functional for this release.

EXT SIG GEN/FRAME SYNCH

Not functional for this release.

FM MOD IN

This BNC connector allows you to use an external signal to frequency modulate the test set's RF generator. It has a fixed sensitivity of 20 KHz/volt, and a frequency range of 100Hz to 20 KHz.

GPIB

This GPIB connector allows test set control with compatible devices.

LAN PORT

This RJ-45 connector provides a connection for downloading firmware upgrades, new applications and for acquiring screen captures. In the lab application only, the LAN PORT is also used for protocol logging.

LAN 2 PORT

This RJ-45 connector provides a connection for transferring data to the test set and for establishing an external device connection between two test sets.

LAN 3 PORT

For future use.

PRINTER

Not functional for this release.

SERIAL 1

Not functional for this release.

SERIAL 2

Not functional for this release.

SERIAL 3

Not functional for this release.

TEST SET SYNCH IN

Not functional for this release.

TEST SET SYNCH OUT

Not functional for this release.

TIMEBASE ADJUST

This is the timebase adjust cover. Removing this screw allows access for timebase adjustment.

TRIG IN

This BNC connector provides the capability for you to trigger measurements or instruments from an external source. Setting the Trigger Source setting to External for measurements or instruments which support this feature causes the measurement or instrument to trigger when a positive-going TTL compatible pulse is applied to this connector. Currently, the only measurement or instrument which supports this feature is the Spectrum Monitor.

TRIG OUT

This BNC connector allows you to synchronize the test set to other equipment via a trigger signal.

VGA OUT

This DB-15 connector allows you to simultaneously route the test set's display to another monitor.

10 MHZ REF IN

This BNC connector accepts an external 10 MHz timebase signal. The nominal input impedance is 50 ohm. This version of test set can only accept a 10 MHz timebase signal.

10 MHZ REF OUT

This BNC connector provides a 10 MHz timebase signal to external test equipment. The accuracy of this signal is determined by the timebase used. The nominal output impedance is 50 ohm with a typical level of 0.5 V rms.
