Description
Amber – Power on but firmware has not run or firmware has been shut down cleanly.
Green – Firmware is running, instrument is probably idle
Flash Green each time a sweep or measurement is triggered (maximum rate will be
around a few Hz).
Additional measurement commands during a flash cycle are ignored by the
flash state machine.
Once the trigger rate exceeds the maximum flash rate, the light flashes until
new measurements stop for a full flash cycle.
Red – The last sweep had an error
Off – Power supply off.
APC 3.5 mm female connector. Sources stimulus signals for the DUT and receives
response signals from the DUT. Frequency range is determined by the analyzer model.
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 an
analyzer in an adjacent slot, the connector receives the LO signal from the configured
analyzer.
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 an
analyzer in an adjacent slot, the connector provides the LO signal to the configured
analyzer.
SMB female connector. When a 10 MHz external reference signal is detected at this
port, it will be used as the instrument frequency reference instead of the internal
frequency reference.
SMB female connector. Outputs a 10 MHz frequency reference signal for use by other
test equipment.
SMB female connector. Inputs a signal to trigger the analyzer.
SMB female connector. Outputs a signal either before or after a measurement.
SMB female connector. Outputs a "READY' signal to other devices.
