Frequently Asked Questions (FAQ) Rigol DG1022Z Arbitrary Waveform Generator

Q1: Does the Rigol DG1022Z produce signals on both channels at the same time?

Yes. The DG1022Z provides two fully independent channels. Both channels operate simultaneously at full specification, so engineers run two different waveforms, frequencies, and amplitudes at the same time without any crosstalk or performance compromise.

Q2: What is SiFi technology and why does it matter?

SiFi stands for Signal Fidelity. Rigol’s SiFi technology reconstructs arbitrary waveforms point-for-point from stored data without interpolating between samples. This approach eliminates waveform artifacts common in conventional DDS generators and produces outputs with 200 ps jitter and -125 dBc/Hz phase noise — critical for sensitive signal-integrity and communications testing Rigol DG1022Z Arbitrary Waveform Generator

Q3: Can I expand the memory beyond the standard 2 Mpts?

Yes. The DG1022Z supports an optional memory upgrade to 16 Mpts per channel. Users purchase the memory option key from Rigol or an authorized distributor like astzbd and activate it via the instrument’s menu without any hardware modification.

Q4: Does the DG1022Z include a frequency counter, or do I need a separate instrument?

The DG1022Z includes a built-in 200 MHz frequency counter as a standard feature. It measures frequency, period, positive pulse width, negative pulse width, and duty cycle. This saves engineers the cost of a separate counter for most routine measurements Rigol DG1022Z Arbitrary Waveform Generator.

Q5: What modulation formats does the DG1022Z support?

The generator supports AM, FM, PM, ASK, FSK, PSK, and PWM modulation. Engineers use internal or external modulation sources and adjust all modulation parameters from the front panel or via remote SCPI commands.

Q6: How do I control the DG1022Z from a PC?

Connect the generator to a PC using the USB Type-B (device) port on the rear panel. The instrument appears as a USBTMC device, and any software that sends SCPI commands controls it — including Rigol’s UltraSigma software, Python with PyVISA, MATLAB, and LabVIEW. An optional LAN interface supports LXI-based remote control over Ethernet.

Q7: Does the DG1022Z work with Bangladesh’s 220 V mains supply?

Yes. The DG1022Z accepts 100–240 VAC at 50/60 Hz, so it operates directly on Bangladesh’s standard 220 V, 50 Hz mains supply without any voltage adapter or transformer.

Q8: What waveform types does the generator support beyond basic sine and square?

Beyond sine, square, and ramp, the DG1022Z includes pulse with adjustable edge times, noise, DC offset, and over 160 built-in arbitrary waveforms such as ECG, Gaussian, sinc, exponential rise and fall, Lorentz, and more. Users also upload custom waveforms from a PC or USB drive.

Q9: Is astzbd an authorized reseller of Rigol products in Bangladesh?

Yes. astzbd sources Rigol instruments through official channels and provides genuine products with valid serial numbers, manufacturer warranty, and local after-sales support across Bangladesh.

Q10: What accessories come in the box with the DG1022Z?
