Rigol DHO1000 & DHO4000

Two new oscilloscope series with 12-bit vertical resolution
RIGOL Technologies has developed two new ASICs for its next generation oscilloscope. With the self-developed Centaurus ASIC chipset, RIGOL is now setting new standards and, with the DHO1000 and DHO4000 families, is launching two high-definition oscilloscope series with a vertical resolution of 12 bits. 

The DHO1000 series has a sampling rate of 2 GSa/s and is offered as a 2-channel as well as a 4-channel solution in bandwidths of 70, 100 and 200 MHz. The maximum memory depth is 100 Mpts. In addition, the DHO4000 series is designed for the 200, 400 and 800 MHz bandwidths with a higher sampling rate of up to 4 GSa/s, contains four analog channels and offers a memory depth of up to 500 Mpts. The minimum vertical adjustment is 100 µV/DIV for the HDO4000 series and 500 µV/DIV for the DHO1000 series. Two different impedances (1 MΩ, 50 Ω) can be set for the DHO4000 series.

The two new ASICs achieve a very low noise level of approx. 18 µVrms (for DHO4000) or 50 µVrms (for DHO1000). As with other RIGOL oscilloscope classes, the focus here was on the combination of high sampling rate, deep memory and very high measurement speed. Even the smallest amplitude deviations can be measured thanks to the vertical resolution of 12 bits. A high-resolution mode of up to 16 bits can also be activated for both devices. This means that very high resolutions in both the horizontal and vertical areas are combined with a very deep memory, thus expanding the variety of analysis.

Typical applications include analysis such as switching performance measurements in the power domain, automated tests in factories, protocol analysis for serial buses in vehicle electronics, electronic circuit measurements, applications in development and many more.

With "Ultra Acquire", RIGOL has integrated a new form of analysis into both series, with which a very fast trigger rate of 1,500 million wfms/sec. is reached. This makes it easy to measure very fast or sporadic and short events. All devices have a very large 10.1 inch HD color capacitive touchscreen (1024*800) with 256 intensity levels and color tones for precise and clear signal display. In order to ensure maximum flexibility, the DHO4000 series allows the integration of a standard 18650 battery in order to carry out measurements without mains connection.

Various trigger, math and display options (extended FFT of 1 million points, mask test and power analysis), an integrated signal search function are available as well as all the usual serial bus protocol analysis and trigger functions. The integrated voltmeter and a frequency counter round off the complete range of measurements. Various interfaces such as USB3.0-Host, USB3.0-Device, HDMI, LAN (10/100/1000 Base-T) and AUX OUT are also available.

An extensive range of accessories, such as active and passive probes, high-voltage probes (differential/single-ended), different current clamps (up to 500 amps), 19-inch installation frame, software drivers for known packages and high-level languages as well as a modern and fast web remote control via LAN is also available. 

The hardware contents photoelectric encoder operating knobs which generate very low wear which results into a long service live. 

As a special feature, RIGOL offers many extensions, such as higher bandwidths, or memory expansion via software upgrade. Serial triggering and decoding (SPI, I2C, RS232/UART, CAN und LIN) are standard implemented in the scope. The risk of a bad purchase is thus minimized, because you can start with a slightly smaller set of equipment and later adapt it to the extended or more demanding measurement requirements in the laboratory. As always, RIGOL hasn't promised too much here and is offering these completely equippable oscilloscopes at the best price/performance ratio. The well-known 3-year Rigol warranty completes the offer for every user.
