SDS7000A Series
Siglent’s flagship bench: 3 to 8 GHz across four channels, a 12-bit ADC, up to 20 GSa/s and 2 Gpts of memory, a million waveforms a second, and a 15.6″ full-HD touchscreen driven by a real Linux workstation.
12-bit resolution, all the way to 8 GHz
Bandwidth normally costs you resolution. The SDS7000A digitises with a genuine 12-bit ADC — 4,096 codes rather than the 256 of an 8-bit instrument — and keeps them right out to the top of the range. At 1 V/div that is eight volts across the screen and roughly 2 mV per code, so 20 mV of ripple riding on a fast edge arrives as ten codes of measurable signal. The same window on an 8-bit scope quantises at 31 mV, and that ripple is simply not in the record to begin with.
In ERES the same acquisition path reaches 16 bits. Behind it sit 3 to 8 GHz of bandwidth on four channels at up to 20 GSa/s, a noise floor of 220 µVrms at 4 GHz and as much as 2 Gpts of memory — with SPO technology painting up to a million waveforms per second, so the glitch that fires once in a hundred thousand cycles is on screen while you are looking at it.
Why it earns the bench space
Twelve bits at these bandwidths is still the exception — much of this class digitises a multi-gigabit edge with eight. The converter is only half the story, so the data sheet also specifies the effective number of bits for every model: what actually reaches the screen once the front end has had its say. At 1,000,000 waveforms per second, rising to 1,100,000 in sequence mode where several instruments at this bandwidth manage a fifth to half as much, the fault that fires once in a hundred thousand cycles turns up in minutes instead of overnight.
And very little of it is chargeable extra. Bode plot, segmented acquisition, 124,000-frame history, search and navigation, SignalScan, DVM, counter, waveform histogram, 60+ automatic measurements, a 32 Mpts FFT and the five everyday serial buses (I²C, SPI, UART, CAN, LIN) are all standard — on rival platforms most of those arrive as separate line items on the quotation. Behind the 15.6″ touchscreen sits a real x86 workstation, Core i3-8100 or better with 32 GB and Linux, so hardware mask testing at 80,000 frames per second and full USB, Ethernet and MIPI D-PHY compliance runs finish on the bench instead of becoming an export-to-PC job for the next morning. Add the SPL2016 and it is a 4+16-channel mixed-signal system.
Five models
Choose the bandwidth your fastest edge needs — then decide whether you need full speed on all four channels at once. Everything else in the series is common.
- 20 GSa/s (2 channels) · 10 GSa/s (3–4 channels)
- 500 Mpts/ch standard
- Full 3 GHz on every channel
- 20 GSa/s (2 channels) · 10 GSa/s (3–4 channels)
- 500 Mpts/ch standard
- Full 4 GHz on every channel
- 20 GSa/s (2 channels) · 10 GSa/s (3–4 channels)
- 500 Mpts/ch standard
- Limited to 4 GHz in 3–4 channel mode
- 20 GSa/s on all four channels
- 1 Gpts/ch standard
- Full 6 GHz on every channel
- 20 GSa/s (2 channels) · 10 GSa/s (3–4 channels)
- 500 Mpts/ch standard
- Limited to 4 GHz in 3–4 channel mode
A model or AP model?
This is the one real decision in the series — and it is about channel count at full speed, not about bandwidth.
SDS7304A · 7404A · 7604A · 7804A
- 20 GSa/s across two channels · 10 GSa/s across three or four
- 500 Mpts/ch standard · 1 Gpts/ch optional in dual-channel mode
- On the 6 and 8 GHz models, bandwidth drops to 4 GHz when three or four channels are active
- Spectrum Analyzer mode (RTSA / DDC) — A models only
SDS7604AP
- 20 GSa/s on all four channels simultaneously
- Full rated bandwidth on every channel — no de-rating
- 1 Gpts/ch standard (1–2 ch) · up to 2 Gpts optional
- No Spectrum Analyzer mode
Rule of thumb: if you regularly probe three or four high-speed signals at the same time, the AP earns its premium. If you work on one or two at a time, an A model gives you the same bandwidth for substantially less.
What every model shares
3 to 8 GHz, 12-bit
Four analog channels with a genuine 12-bit ADC (16-bit in ERES) — the vertical resolution to see what an 8-bit scope buries in quantisation noise, at bandwidths up to 8 GHz.
Up to 20 GSa/s
20 GSa/s of real-time sampling, and on the AP models that rate is available on all four channels at once rather than only two.
Up to 2 Gpts memory
500 Mpts/ch as standard, 1 Gpts/ch standard on AP models and up to 2 Gpts optional — long enough to capture a slow event at full sample rate.
1,000,000 wfm/s
SPO technology with 256-level intensity grading and colour-temperature display, so infrequent anomalies actually appear on screen.
Workstation inside
An Intel Core i3-8100 or better with 32 GB of memory and 250 GB of storage running Linux — which is what makes 32 Mpts FFT and deep analysis usable.
15.6″ full-HD touch
A 1920 × 1080 capacitive multi-touch display with gestures, plus DVI-D, DisplayPort and HDMI out, mouse, keyboard and browser control over dual gigabit LAN.
Analysis that usually needs a second instrument
Licensed software that runs on the scope’s own workstation hardware.
Eye diagram & jitter analysis
A colour-graded eye built from the captured signal, with the full jitter breakdown underneath — TJ, RJ, DJ and the rest — so you can tell a random noise problem from a deterministic one. This is the measurement that decides whether a high-speed link ships, and on the SDS7000A it is a licence rather than a separate instrument.
Power analysis
Switching loss, harmonics against the limit line, modulation, inrush and safe-operating area — computed on the scope with the harmonic table alongside the waveform. Pair it with the DF2001A deskew fixture: at these edge rates, a few hundred picoseconds of probe skew is the difference between a real loss figure and a fictional one.
Ethernet & USB compliance test
Automated pass/fail against the standard’s own template: 100BASE-T, 1000BASE-T, the automotive 100BASE-T1 and 1000BASE-T1 variants, and USB 2.0. Catch a compliance failure at your bench, not at the test house.
Built-in 50 MHz generator
The SDS7000A-FG licence turns on an internal arbitrary/function generator — 50 MHz, 125 MSa/s, 16 kpts — for stimulus-response work and Bode plots without dragging a separate source onto the bench.

Frequently asked questions
What is the difference between the A (H12) and AP models?
Sampling and memory. The A models give 20 GSa/s across two channels and 10 GSa/s across three or four, with 500 Mpts/ch standard; on the 6 and 8 GHz A models the bandwidth is limited to 4 GHz once you use three or four channels. The AP models deliver the full bandwidth and 20 GSa/s on all four channels simultaneously, with 1 Gpts/ch standard and up to 2 Gpts optional. One caveat in the other direction: the Spectrum Analyzer mode is available on A models only.
Which model should I choose?
Pick the bandwidth your fastest edge needs, then decide how many channels must run at full speed at once. If you routinely probe three or four high-speed signals together, the AP is worth the premium; if you mostly work on one or two at a time, an A model gives you the same bandwidth for considerably less.
Can I upgrade the bandwidth later?
Yes, by software licence: SDS7000A-BW3T4 takes a 3 GHz model to 4 GHz, and SDS7000A-BW6T8 takes a 6 GHz model to 8 GHz. No hardware change and no return to the factory.
Is it a mixed-signal oscilloscope?
Yes, with the optional SPL2016 logic probe: 16 digital channels at up to 1 GSa/s and 50 Mpts, decoded and displayed alongside the four analog channels.
What comes as standard versus a paid licence?
Standard: the full trigger set with Zone Trigger, I²C/SPI/UART/CAN/LIN decode, 60+ measurements, 32 Mpts FFT, Search, Navigate, SignalScan, Mask Test, Bode plot, DVM, counter and histogram. Licensed: eye/jitter analysis, power analysis, the waveform generator, the compliance tests and the additional serial protocols.
How do I control it remotely?
It has a built-in web server reachable from a browser over either of its two gigabit LAN ports, full SCPI over LXI/VXI-11/socket/telnet and USBTMC, and it accepts an external mouse and keyboard. Video can be mirrored out over DVI-D, DisplayPort or HDMI.
