View image.Connector routing is supported only on the M9484C. Connector routing is used to associate the physical connectors to features of signal generation.
For the M9484C, Trigger Connectors can be used for routing as input or output. The available connectors are based on the instrument’s channels and options:
For channel 1 without Option AN1, and channels 2, 3, or 4, the connectors are:
Trig 1, Trig 2, Trig 3
For channel 1 with Option AN1 the connectors are:
Trig 1, Trig A, Trig B, Trig C, and AIO 1 through AIO 12
Connectors Trig A, Trig B, Trig C output bandwidth is limited to 100 MHz; when they are set for output, 3.3 V is the high voltage
Connectors AIO 1 through AIO 12 the input bandwidth is limited to 1 MHz
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.

The query result will be the labels on the front or rear panel of the instrument. The return value is a string that may contain whitespace characters; for example "Trig A". For M9484C: For Channel 1 without Option AN1, and channels 2, 3, 4: 1 = "Trig 1" 2 = "Trig 2" 3 = "Trig 3" For Channel 1 with Option AN1: 1 = "Trig 1" 4 = "Trig A" 5 = "Trig B" 6 = "Trig C" 7 = "AIO 1" 8 = "AIO 2" … 18 = "AIO 12" Thus: RF1:TRIG[1]|4|5|6|7|8|9|10|11|12|13|14|15|16|17|18 are available connectors when Option AN1 is present RF1 available connectors without Option AN1 are TRIG[1]|2|3 RF2|3|4 available connectors are TRIG[1]|2|3 |

For M9484C: 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.
For the M9484C, Event connector routing can output markers from one or more signals, given the following criteria:
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 number from signal number 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.

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. |

The Edit Timer Trigger button is displayed when you select Timer Trigger as the source for triggering a sweep. Clicking this button opens the Instrument Settings > Triggers and Sync > Timer Trigger tab. You can use this tab to configure the Timer Trigger Period for channels. To know more, refer to the topic Triggers and Sync.
Sets the time interval of the timer trigger source. There is only one timer trigger source for each RF channel. Therefore, the value remains the same in all trigger source selections for the channel.

For M9484C with Option DS1
You can use the Optical Digital Interface (ODI) Streaming feature to provide the M9484C with I/Q data generated in real-time or stored in a large storage.
Step 1 - Set up the Hardware
Connect the following Keysight ODI cable to the ODI port of the channel on the front panel of your instrument.
M8121-61614 - Patch cord, ODI, F-F, 24 fiber, Type C, 3 M
If the M9484C configuration has Option AN1 (Analog I/O), then the ODI port is not available for channel 1.
Step 2 - Configure ODI Connector settings and then Enable ODI Port for the channel. Use Connectors > ODI Streaming tab to perform this step.
Step 3 - Select the Mode as ODI Streaming for the required Signal(s) (using Signals Setup > General > Mode)
Step 4 - Configure ODI Streaming settings for the required Signal(s) (using Signals Setup > ODI Streaming tab)
Step 5 - Enable the signal(s) for which you configured the ODI Streaming mode.
The SCPI commands for the ODI Connector are described below.
Enables or disables ODI Streaming input on the specified RF Channel.
If Option AN1 is configured for channel1, then channel1 is not available for enabling ODI streaming .

Notes |
ODI Streaming cannot be enabled on a channel using Real Time Vector Modulation or if the channel is not configured as Independent. For M9484C without option DS1, attempting to enable this setting issues 703 Feature not supported error. For M9484C with option DS1, if the channel uses Real Time Vector Modulation or is not configured as Independent, attempting to enable this setting issues -221 Settings conflict error. |
