KEY FEATURES
FEATURES
Low-Distortion Continuous Waveform Output
Leveraging digital sampling technology, our output ensures reliable harmonic performance with an -80dBc spurious-free dynamic range and delivers exceptionally low jitter for a pure, stable signal.
Pulse Wave and Fast Edge Time
The pulse wave offers precision-adjustable edge times down to 2ns and a minimum pulse width of ≥3ns, with 100ps fine-tuning. It generates high harmonic content, rivalling dedicated pulse generators, and allows independent edge-time setting for each pulse.
Four-Channel Independent Output
Featuring four fully independent channels, this instrument delivers high-performance output signals simultaneously for efficient multi-device or parallel testing applications.
Flexible Channel Coupling & Merge Outputs
Channels can be freely coupled with configurable frequency, amplitude, and phase parameters.
Channel outputs may also be combined as needed, such as CH2 = CH1; CH1 = CH1 + CH2 + CH3 + CH4.
4-Channel Synchronization
This function enables synchronized control of all four channels. Adjusting one channel automatically updates the other three in unison.
One-Click SNR
The instrument features continuous waveform noise superposition. This allows Gaussian noise to be added to the main signal for direct evaluation of a device’s anti-noise performance.
Rich Modulation Modes
Supports AM, DSB-AM, FM, PM, ASK, FSK, 3FSK, 4FSK, PSK, BPSK, QPSK, OSK, QAM, PWM, SUM modulation outputs, for a total of 15 distinct types.
Digital Protocol Output
Digital protocol output: SPI, I²C, UART
High-Precision Frequency Counter
Equipped with a high-precision hardware frequency counter, capable of measuring frequencies from 100mHz to 800MHz.
Edit Arbitrary Waves
Create or edit any waveform freely—both directly on the instrument and on a connected PC. With over 200 built-in waves and intuitive drawing or math tools.
Rich Advanced Functions
New series function/arbitrary waveform generator comes standard with advanced waveform output capabilities, including multi-pulse, multi-tone, sequence, pattern, I/Q, and expression-based waveforms.
