(Not supported)TRG OUT MMCXfemaleTrigger Out signal. User selectable from several functions.I/O 1, 2, 3 MMCXfemaleUser configurable Input / Output signal. 3.3 V CMOS andTTL compatible.CLK INMMCXfemaleExternal clock input. AC coupled and 50 Ω terminated, signal level: +5to +15 dBm. (Please refer to product user manual or datasheet for sup-ported frequency values).REF IN MMCXfemaleExternal reference clock input, AC coupled and 50 Ω terminated. It canaccept a 100 MHz signal from -3 to +3 dBm.The ADC Card can usually work with signals present at the externalreference and clock inputs (REF IN and CLK IN). However, to ensure thebest performance, or if the calibration is found to be unreliable, it isrecommended to remove such signals when working with internal clock.
