RSA-DKIT USB Demonstration Kit for Spectrum Analyzers Datasheet

Specifications

All published performance is typical.

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)

RUN MODE

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.
