Front Panel Connectors
Last updated: October 28, 2004
Description
AUDIO IN
The input to the audio analyzer is a floating input differential amplifier. Both the AUDIO IN High and AUDIO IN Low BNC connectors should be connected to provide noise immunity. Refer to the
Technical Specifications in the Application Datasheet
for more information.
AUDIO OUT
This BNC connector accesses the test set's Audio Generator and FM Demod signals. The Audio Generator is used to stimulate a system to measure audio performance characteristics. The FM Demod allows the user to access the demodulated FM signal for external analysis and baseband processing. Refer to the
Technical Specifications in the Application Datasheet
for more information.
There will be no guaranteed performance for the signal present at the AUDIO OUT connector when FM Demod signal is selected for output.
DATA
This RJ-45 connector provides front panel access to the rear panel LAN connection. This connector is used for downloading firmware upgrades, or new test applications into the test set. No other types of communication are possible with the LAN port.
The the DATA connector on the front panel is connected internally to the ETHERNET TO FRONT PANEL connector on the rear panel. In order to use the front panel DATA connector, connect the rear panel LAN PORT, to the rear panel ETHERNET TO FRONT PANEL connector with the LAN jumper cable.
The LAN jumper cable, part number E5515-61160, is supplied with the test set.
DVM
Not functional for this release.
RF IN/OUT
This Type-N connector is the default path for all RF signals out of the test set, and is always used as the RF input. Refer to the
Technical Specifications in the Application Datasheet
for more information. See also
RF OUT ONLY
.
RF OUT ONLY
This port cannot be used with the E1960A GSM test application or with the GSM personality in a test application suite (such as the E1985A GSM_AMPS/136_GPRS suite).
This Type-N connector is an optional path for all RF signals out of the test set. It is intended to be used for duplexed testing. Front panel selection of this port is provided by the
RF Output Port
(
F6
) control on the System Config screen, and by the RFGenerator:OUTPut[:DESTination] IO/OUT command. The same amplitude offsets and output power settings are used for either selected port (RF IN/OUT or RF OUT ONLY). Refer to the
Technical Specifications in the Application Datasheet
for more information.
