Page 47: Triggering The Instrument Externally
Triggering the instrument externally The example configurations are rather theoretical cases, because you rarely use the R&S SMM100A as a stand-alone instrument. Usually, you connect the instru- ment to a device under test (DUT) or other measurement equipment. As a rule, whenever a test setup requires two or more devices, provide them with a com- mon reference frequency. - Page 48 52. To verify the current connector configuration The R&S SMM100A is equipped with multipurpose bi-directional User connec- tors. Because the signal direction, input or output, and the signal mapping are configurable, we recommend that you check the current configuration before cabling or further instrument's configurations.
- Page 49 ® Trying out the instrument R&S SMM100A Triggering the instrument externally The instrument uses its internal trigger and clock signals, and the default map- ping of the marker signals to the connectors. 2. To open the related connector settings, select "Global Connectors".
- Page 50 ● The "User 3" connector is an input for the trigger signal "Global Trigger 1". Check the front panel of the R&S SMM100A. The LEDs next to the "User 1" and "User 2" connectors are yellow. The LED next to the "User 3" connector is green.
- Page 51 ® Trying out the instrument R&S SMM100A Triggering the instrument externally The instrument expects an external global trigger event. In the block diagram, the "TMC" status LED confirms that an external trigger signal is available that triggers the signal generation.
- Page 52 DUT can be the source for the reference signal. Instead of an external trig- ger source, the DUT can send, for example, a frame trigger signal to the R&S SMM100A. The R&S SMM100A remains the signal generation source. To generate an RF signal with an external trigger 1.
- Page 53 R&S SMM100A Triggering the instrument externally If the R&S SMM100A receives the external trigger event, it starts continuous signal generation. Arming the trigger stops the signal generation until the next trigger event restarts the signal generation. 2. Select "RF" > "On".
