-40 to 60°C (-40 to 140°F) 20 to 90% RH (non-condensing) Spirent recommend you always operate your equipment in a controlled environment that conforms to the parameters in the table above. Do not use your equipment outside the operating parameters in the table above (for example, in a tropical or cold environment). -
Page 12: Ventilation
Remove any accumulated dust using a vacuum cleaner. Spirent recommend you inspect the heat sink fitted to each signal generator card on a regular basis. Dust build-up on these heat sinks could adversely affect the operation of your signal generator, eventually leading to thermal shutdown. -

Including feet: 198 (7.8) 2.13 Embedded Host BIOS battery The Embedded Host uses a battery to store BIOS settings. Should this battery fail, your GSS7000 signal generator will continue to function as normal. Spirent recommend replacing the BIOS battery every three years. The installed PosApp software contains a warning feature that alerts the requirement to change the battery three years after date of build, calibration or BIOS battery replacement. -
Page 14: Disposal
Spirent simulator products meet the requirements of the European Union (EU) Waste Electrical and Electronic Equipment (WEEE) Directive. The WEEE Directive requires Spirent to label products placed on the EU market after 13th August 2005 with this ‘wheeled bin’ symbol: This symbol indicates the product contains material that presents an environmental concern. -

Page 23: Gss7000 Overview And Installation
4.1 Front panel GSS7000 signal generators have single, or (optionally) dual, RF Out ports. Each RF Out port is a "composite" output port, with all satellite channels available on this port, together with any signal you apply to the rear panel EXT RF IN port. Each RF out port is the normal connection point for your device under test. -
Page 24: Front Panel Indicators
SAFETY WARNING You must ensure any connection to a rear panel port is within the SELV limits of IEC62368. The following figure shows the rear panel of a GSS7000 signal generator. Spirent might not fit all connectors for certain configurations. -
Page 25: Rear Panel Ports
The following tables describe all rear panel connectors. It groups the connectors into nominal groupings as viewed when looking at the rear panel. Where a port is identified as having a terminator during testing, Spirent recommends that you keep the port terminated when not in use to maintain the system’s performance. - Page 26 In addition, you can set any of the above to run as: Ungated: continuously running Gated: only present while a scenario is running The default timer settings for a stand-alone GSS7000 signal generator are: Timer 1: 1PPS UNGATED Timer 2: 1PPS UNGATED ...

Page 27: Usb Port Assignment
4.2.2 USB port assignment You must assign each available GSS7000 signal generator USB port to either Linux or Windows whenever you insert a USB device. The GSS7000 Embedded Host automatically recognises connection of a USB keyboard and mouse; you do not need to assign these USB devices. - Page 28 USB port to Linux, such as when using a USB to RS232 adapter for GBAS messages when using a GSS4150 GBAS Landing System VDB signal generator with the GSS7000 signal generator. Following the steps in this section will reset the current USB port assignments for all USB ports on the GSS7000 Embedded Host.
