Description

The UTG4254X delivers 250 MHz output frequency on four equivalent channels at 2.5 GSa/s sampling rate and 16-bit vertical resolution. The DDS technology produces precise, stable signal shapes with fast rectangular signals. It supports comprehensive analogue and digital modulation types, PRBS, sweep and burst operation as well as the extended signal forms Multi-Pulse, Sequence, Multi-Tone, IQ and Pattern. With 128 Mpts arbitrary memory, integrated signal form editor, frequency counter and 10.1-inch TFT LCD touch screen, the device is versatile in development, training and general electronic testing.

Features

Low-distortion signal output: Interference-free dynamic range of -80 dBc and low jitter for clean, stable signals
Quick edge time: Flank time up to 2 ns, minimum pulse width ≥3 ns, fine adjustment in 100-PS steps, Face time per pulse adjustable
Four independent channels: Simultaneous output on all channels for parallel and multi-device testing
Channel coupling & signal addition: Frequency, amplitude and phase can be freely coupled, outputs can be combined (e.g. CH1 = CH1 + CH2 + CH3 + CH4)
4-channel synchronization: Change to one channel automatically transfers to the other three
One-Click SNR: Overlaying Gauss Noise for direct evaluation of immunity
15 MODULATION TYPES: AM, DSB-AM, FM, PM, ASK, FSK, 3FSK, 4FSK, PSK, BPSK, QPSK, OSK, QAM, PWM, TOTAL
Digital protocol output: SPI, I²C and UART
Hardware frequency counter with a measurement range from 100 MHz to 800 MHz
Arbitrary signal editor: Over 200 integrated signal shapes, processing on the device or at the PC by character and mathematical functions
Standard extended signal shapes: Multi-pulse, multi-tone, sequence, pattern, IQ and Exp
