Siglent SDS1104X-E 100 MHz 4-Channel Super Phosphor Oscilloscope

SDS1104X-E is the 100 MHz, four-channel model of the Siglent SDS1000X-E Super Phosphor Oscilloscope series, with up to 1 GSa/s sampling, up to 14 Mpts of memory, a 7-inch display and IIC, SPI, UART, CAN and LIN decoding fitted as standard.

A four-channel scope with decoding included

Siglent builds the SDS1000X-E on its SPO technology: 256-level intensity grading, a colour-temperature display mode, and capture rates of up to 100,000 waveforms per second in normal mode and 400,000 in sequence mode. The four-channel models have two 1 GSa/s converters, so each channel samples at 500 MSa/s with all channels on and 1 GSa/s when only one channel per pair is used.

Memory is 7 Mpts per channel with all channels active and up to 14 Mpts per channel in interleave mode. Math and measurements use all sampled points, and a hardware co-processor keeps the screen responsive while it works. History recording keeps up to 80,000 frames and segmented acquisition splits memory into up to 80,000 segments with timestamps.

Key features as printed in the datasheet

• 38 automatic measurement parameters with statistics, gating, zoom, math and reference functions.
• 1 Mpts FFT; four-channel models add peaks, markers, search and navigate, labels, counter and data logger.
• Hardware pass/fail with up to 40,000 decisions per second.
• Bode plot for power-supply loop response (four-channel only).
• Optional 16-channel MSO (SLA1016) and 25 MHz USB AWG (SAG1021I).

Choosing between the SDS1000X-E models

The datasheet covers three order codes: SDS1104X-E (100 MHz, four channels), SDS1204X-E (200 MHz, four channels) and SDS1202X-E (200 MHz, two channels plus external trigger). Only the four-channel models support the 16-channel logic option, the AWG module, Bode plot, search, counter, labels, logger and browser control. Standard accessories are four PP510 passive probes, a USB cable, quick start guide, certificate and power cord.

Set-up notes

Keep inputs within 400 Vpk and use a rated probe for anything higher. The scope has no hazardous-area rating and is specified for 0 to +40 °C, so install it in an air-conditioned workshop rather than an outdoor kiosk. Serial decoding appears as an events table, and the Default key can be customised through the Save menu to recall your own preset.

Workshop, college and production uses

At 100 MHz with four channels it covers PLC and drive electronics, switch-mode supplies, sensor signals and automotive CAN and LIN checks for service benches and technical colleges. Pass/fail testing against a template suits repetitive production checks. Four channels are useful when you need to see gate drive, current and bus decode at once.

Optional items listed by Siglent

Siglent lists the SLA1016 16-channel logic analyzer, SAG1021I isolated 25 MHz AWG module, ISFE isolated front end, STB-3 demo source, HPB4010 high-voltage probe, CP series current probes, DPB series differential probes and the SDS1X-E-RMK rack mount. See the Portable Test and Measurement category.

Selection and installation notes

Test and measurement instruments are selected from the accuracy, the range and the interfaces the work needs. Allow the warm-up time, use leads and probes rated for the voltage and category of the circuit, keep the inputs inside the stated limits and keep the calibration current according to your quality system. Record the settings used for any test that must be repeated later.

Information needed for a quotation

Send the full model code, the quantity, the delivery location in Oman or the GCC, the intended use and any accessories needed, so that the complete package can be quoted together.

Documents and supply information

The manufacturer data sheet is attached to this page and should be read together with the project specification and the site risk assessment before a purchase is confirmed. Ratings, standards and dimensions are quoted as printed on that sheet. Lead time, stock position and certificates available with the shipment are confirmed in the quotation, and we supply to Oman and the wider GCC region for industrial, utility and building services projects.

Frequently asked questions

What is the bandwidth and memory of the SDS1104X-E?

100 MHz bandwidth on four channels, with up to 1 GSa/s sampling and up to 14 Mpts of memory per channel.

Which serial buses are decoded?
