  • Specification

✨ Why It Helps (Cause → Effect)

  • 250 MHz headroom → high-freq checks stay honest → filters, amps, and clocks behave as expected.

  • Arbitrary + standard waveforms → real shapes, not just sines → devices see true-to-life stimuli.

  • Stable amplitude/phase/frequency → repeatable outputs → trustworthy data.

🎛️ Operate Fast (Action → Result)

  • Intuitive GUI + clear menus → find → set → run → fewer clicks, fewer mistakes.

  • Quick edits on screen → amplitude/frequency/offset in seconds → keep the bench moving.

  • Modulation options (AM/PWM/FSK/IQ, burst, sweep*) → stress the DUT → reveal margin and drift.
    *Frequency-hopping available as a software option on supported configs.

🔌 Connectivity (Plug → Automate)
USB-Host / USB-Device / RS-232 / LAN / GPIB → SCPI control → script tests, clone setups, log results easily.

🧪 Where It Fits (Use → Payoff)

  • R&D bring-up → custom arbs poke edge cases → bugs surface early.

  • Product test → stored setups → consistent, defensible results across lines.

  • Education → friendly UI → faster learning, less downtime.

📡 AM Modulation
Change amplitude with your message → carrier grows/shrinks → receivers hear info cleanly.

⏱️ PWM Modulation
Vary pulse width → control average power → motors, LEDs, drivers respond smoothly.

🎚️ FSK Modulation
Hop between two tones → bits ride as frequency shifts → robust digital links in noise.

🧭 IQ Modulation
Blend I (in-phase) + Q (quadrature) → shape complex constellations → tighter, cleaner spectra.

🗺️ IQ-Mapping Editor
Draw/customize symbol points → prototype new constellations → test radios against real impairments.

🎯 IQ-Mapping Selection
Pick ready-made maps (QPSK, 16/64-QAM, etc.) → match standards fast → compare results apples-to-apples.

💥 Burst Function
Gate signal on/off → timed packets on demand → mimic time-slots and save power.

📈 Sweep Function
Slide frequency/amplitude/phase → reveal resonances and bandwidth → find sweet spots quickly.

🏃 Frequency Hopping (Software Option)
Jump channels rapidly → dodge interference → improve link reliability in crowded bands.
