AppendixFront Panel FeaturesFeature DescriptionStatus LED Amber – Power on but firmware has not run or firmware has been shut down cleanly.Green – Firmware is running, instrument is probably idleFlash Green each time a sweep or measurement is triggered (maximum rate will bearound a few Hz).Additional measurement commands during a flash cycle are ignored by theflash state machine.Once the trigger rate exceeds the maximum flash rate, the light flashes untilnew measurements stop for a full flash cycle.Red – The last sweep had an errorOff – Power supply off.Port 1 APC 3.5 mm female connector. Sources stimulus signals for the DUT and receivesresponse signals from the DUT. Frequency range is determined by the analyzer model.Port 2LO In APC 3.5 mm female connector. If the module is not configured with another analyzer,the connector is terminated with a 50 ohm load. If the module is configured with ananalyzer in an adjacent slot, the connector receives the LO signal from the configuredanalyzer.LO Out APC 3.5 mm female connector. If the module is not configured with another analyzer,the connector is terminated with a 50 ohm load. If the module is configured with ananalyzer in an adjacent slot, the connector provides the LO signal to the configuredanalyzer.Ref In SMB female connector. When a 10 MHz external reference signal is detected at thisport, it will be used as the instrument frequency reference instead of the internalfrequency reference.Ref Out SMB female connector. Outputs a 10 MHz frequency reference signal for use by othertest equipment.Trig In SMB female connector. Inputs a signal to trigger the analyzer.Trig Out SMB female connector. Outputs a signal either before or after a measurement.Trig Ready SMB female connector. Outputs a “READY’ signal to other devices.
