Spectrum analyzers are versatile tools capable of hundreds of different measurements. Creating signals and learning how to get the most out of your analyzer can be a challenging task. The RSA-DKIT gives you the essential tools you need to understand measurement concepts and operating methods for Tektronix spectrum analyzers. With this package you can learn to make basic spectrum measurements, spurious measurements, channel power and ACPR, modulation measurements of various signal types and analog AM/FM measurements. No additional equipment is required, and the kit contains a printed demonstration guide that takes you through measurements.

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.
