Siglent Technologies launches low profile oscilloscopes

The SDS6000L digital oscilloscopes have the same performance as the SDS6000A models, launched in 2021, but in a very compact format, which makes it possible to multiply the number of measurement channels.

In a world where computers and communication systems are becoming more and more complex and powerful, it is important to understand how the subsystems interact with each other. To do this, development and test engineers must validate operation at the complete system level, that is, across multiple programs and subsystems.

But such systems very often require the collection and analysis of a large number of signals, at least much more than the four measurement channels of a traditional digital oscilloscope. This is how Chinese Siglent Technologies has just unveiled the SDS6000L series with six models. low profile ” various.

If each of the new oscilloscopes does not have a screen, they are distinguished above all by the number of analog channels available as standard, namely 4 or 8 channels, and by the form factor, a 19-inch rack of 1U and 2U respectively. . This compactness saves a lot of space when a model is integrated into a measuring system.

Several SDS6000Ls can also be combined into a multi-channel system. The manufacturer also offers to synchronize such a system with the SYN64 module. By connecting its outputs to the EXT trigger or to the analog channel of the oscilloscopes, it acts as a trigger source for the latter and even makes it possible to calibrate crooked between channels (30 ps typically within a group or 140 ps typically between groups) and the delay of each analog channel and the cable.

On the performance side, we find the SDS6000A series oscilloscopes launched in October 2021. The bandwidth is 500 MHz, 1 or 2 GHz, depending on the model. The sampling rate reaches 5 GS/s per channel or 10 GS/si ESR mode (Improved sample rate), under a vertical resolution of 8 bits (12 bits in ERES mode [Enhanced Resolution] equivalent to 16 bits in Hi-Res mode).

Siglent Technologies has leveraged the SDS6000A’s optimized input stage to deliver SFDR dynamics in excess of 45dBc, channel-to-channel isolation up to 70dB and continuous amplifier accuracy of ±1.5%. This performance is an advantage when analyzing small signals in the vertical adjustment range of 500 µV.

Other specifications include a maximum standard refresh rate of 170,000 waveforms per second. second (750,000 waveforms per second) using SPO technology, memory depth of 125 Mpoints on four lanes or up to 500 Mpoints on one lane.

Users will also benefit from serial bus triggering and decoding (I2C, SPI, UART, CAN and LIN as standard, CAN FD, FlexRay, I2S, SENT, MIL-STD-1553B and Manchester as options), current and jitter (options -PA and -EJ), 16 logic channels (1 Gsample/s, 50 Mpoints per channel; -16LA option), a function generator (25 MHz, 125 Msample/s under 14 bits; -FG option), etc.

Finally, in the absence of an integrated display, the new compact oscilloscopes each integrate USB, LAN, HDMI, etc. interfaces. and the same web server for the other devices from the manufacturer must be “autonomous” devices and be controlled remotely without external software.
