ERTA (Extended Range Transmission Analysis) Mode - Option 209
Requirements and Limitations
Requirements and Limitations
Requirements
— Two FieldFox units with option 209 installed. SA Mode is required for option
209.
— Ethernet LAN cable(s). Either TWO cables that are used to connect both
units to the internet or ONE cable that is long enough to connect the two
FieldFox units. This may require a cross-over cable.
— Two trigger cables that are long enough to connect the two FieldFox units,
each with SMB (m) to SMA (f) connectors.
— RF cabling to and from DUT.
— Power Splitter (Optional) for enhanced B/R ratio measurements.
Limitations
The following SA features are removed in ERTA mode (Option 209):
— Channel Measurements, Tune and Listen, Interference Analysis, Radio
Standards, and Sweep Triggering.
The following SA features are disabled during partnership synchronization:
— Video BW, SwpAcquisition, Frequency Count, Record/Playback, and certain
Amplitude Units.
— The only keystrokes allowed on the Source unit are Send Text Message and
Exit.
When you change network connections, it may take up to 2 minutes for
the old address to be replaced by the new address. If the FieldFox was
initially assigned an IP address by a DHCP server, and then the FieldFox
LAN connection with a DHCP server is removed and is the FieldFox is
reconnected to a LAN segment with no DHCP server (such as a direct
connect to another FieldFox), the FieldFox may take up to two minutes to
self-assign an automatic private IP address. During this connection time
the last recognized DHCP address is displayed on the FieldFox, but is
invalid.
