| Controls |
| ON/OFF |
Power switch (LED red when on) |
| ROW / COLUMN (Signal selectors) |
Selects desired signal
Signal output at RF Output starts ~2 s after selection,or when Signal LED stops blinking. |
| INT/EXT - select between |
INT:Internal signal / modulation (LED on)
EXT:Use EXTERNAL I/Q modulation inputs (LED on)
OFF:No output (LED on)FREERUN
Waveforms continuously output (LED on)
Single
Single instance / pulse output (LED on), press TRIGGER to generate
When in SINGLE mode, the TRIGGER LED blinks at about a 1 Hz rate to indicate it's waiting for a trigger event. |
