|---|---|---|---|
Trigger Connectors can be used for routing as input or output. The available connectors are based on the instrument’s channels and options.
For
For all channels, the trigger connectors are:
Trig 1, Trig 2, Trig 3, Trig 4, Trig 5, Pulse In
Via SCPI, the connectors are referenced by a number; 1 to the maximum number of connectors. A SCPI command can be used to provide the connector label for the corresponding number.

Applies to N5186A only.
For N5186A: These three output-only connectors have precise timing (at 3 GHz) for markers on baseband signals. The maximum rate of change is 600 MHz. If an Event output is configured to change too quickly, the output will only change on 600 MHz boundaries, regaining the proper level and precise timing wherever the rate of change is 600 MHz or less.
Event connector routing can output markers from one or more signals, given the following criteria:
For each connector, only one marker can be selected from each signal.
Only per-signal marker selections for a connector can be ORed together. Note: If any are asserted, the output is asserted.
Per-signal marker selections cannot be combined with None or the single uniform Marker for all signals.
Event routing options:
None (NONE) - The connector is off.
Signal Marker Source(S<n>M<n>) - The Event output is asserted when the marker m from signal s is asserted. If more than one signal/marker combination is selected, then if any of them are asserted the connector output is asserted. Only one marker can be chosen from any one signal, so the list of marker selections is limited to the number of signals.

For E82x7D and E8663D: When NOISe, DUALsine, or SWEPtsine is selected, this command will not change the LF Output Source but comprise a Noise, Dual, or Swept Function Generator respectively. When specified source is Function 1 and shape is DUALsine, Function 1 comprises a dual function using dual function settings, apart from: • Dual Function Generator Frequency 1 will use Function Generator 1 Frequency. When specified source is Function 1 and shape is SWEPtsine, Function 1 comprises a swept function using swept function settings, apart from: • Swept Function Generator Start Frequency will use Function Generator 1 Frequency. When specified source is Function 1 and shape is NOISe, Function 1 comprises a noise generator that uses the Noise Generator 1 Type setting. When specified source is Function 2 and shape is NOISe, Function 2 comprises a noise generator that uses the Noise Generator 2 Type setting. Once shape is set to NOISe, DUALsine, or SWEPtsine, the LF Output Source can only be restored to the true Function 1 or 2 from the given, comprised function when shape is set to SINE|TRIangle|PULSe|RAMP|SQUare. |
For instruments with Option 303 on channel 1, sets the ramp direction when LF output function generator shape is set to Ramp.
