SSB Phase Noise @ 10 MHz and +13 dBm output level*:
At 1 Hz < -135 dBc/Hz
At 10 Hz < -145 dBc/Hz
At 100 Hz < -153 dBc/Hz
At 1 kHz < -160 dBc/Hz
At 10 kHz < -163 dBc/Hz
* See chart below for typical additive phase noise performance.
External Alarm Input/Disable Inputs (A or B):
Normal State: TTL low.
Alarm State: TTL high or high Z (internal 10kΩ pull-up).
Connectors: Rear-panel female BNCs labeled “Disable In”.
Alarm Output:
Open-collector, 40 VDC Max, 100 mA Max Saturation Current.
High Impedance when any fault condition exists.
Connector: Rear-panel female BNC labeled “Alarm Out”.
Front-Panel System Status Indicators:
Signal Input LEDs: Red/Green/Yellow LEDs indicate signal presence, selection status of each Signal
Input and, if configured, Disable Input (external alarm input) status.
Signal Output LEDs: Red/Green/Yellow LEDs indicate signal presence status on each output.
Power LEDs: Red/Green LEDs indicate power supply status of each power input.
Alarm LED: Red/Green/Yellow LED indicates a serious fault condition.
Maintenance Port:
