SDS1000DL+ Series
One model, and the lowest entry price Siglent offer: the SDS1052DL+ — two channels at 50 MHz, 500 MSa/s, a full 7-inch 800 × 480 screen, 32 automatic measurements, LAN and hardware pass/fail, for €277.
The least expensive oscilloscope Siglent still make
The SDS1000DL+ series has one member in Europe, the SDS1052DL+. It is a conventional, well-proven two-channel digital storage oscilloscope: 50 MHz, 500 MSa/s in real time, 32 kpts of record length, and a full 7-inch 800 × 480 colour display rather than the small one an entry price usually buys.
The useful parts of a laboratory instrument are all there. Thirty-two automatic measurements with five on screen at once, manual, track and auto cursors, a 6-digit hardware frequency counter, maths including an FFT with four window functions, a zoom window, a digital filter, a continuous waveform recorder, and a hardware pass/fail comparator that drives a TTL line on the rear panel. It has a LAN port with VXI-11 and USB-TMC, so it scripts over SCPI like any other instrument.
What it does not have is memory, bandwidth or serial decoding, and there are no options that add them. That is the honest shape of a €277 oscilloscope — and because the next instrument up costs €13 more, the comparison below is the most useful thing on this page.
The €13 question — read this before you order
The SDS1052DL+ sits at the bottom of a very short ladder, and the first rung costs almost nothing. The SDS1102CML+ is the same chassis with the same menus, the same manual and the same case — and it is €13 more. We would rather show you this than have you find it afterwards. Bold marks the better figure in each row.

Buy the SDS1052DL+ when
The budget line genuinely will not stretch — a purchase order is a purchase order. Or you already run a fleet of SDS1000DL+ units and want another that behaves identically, takes the same probes and is covered by the same training. Or your signals are audio, mains-frequency, power or slow sensor outputs, where 50 MHz and 32 kpts were never going to be the limit.
Spend a little more when
Almost any other time. €13 buys the SDS1102CML+: double the bandwidth, double the sample rate and sixty-four times the record length. €62 buys the SDS1202X-E, a generation newer, with 200 MHz, 14 Mpts and I²C, SPI, UART, CAN and LIN decoding included. If you will ever look at a serial bus, that is the one.

What €277 does buy
All standard. There are no licences or options for this model.
The lowest entry price Siglent offer
This is the least expensive oscilloscope in the current Siglent European price list. When the constraint is the budget line rather than the specification, that is the whole argument.
A full 7-inch 800 × 480 screen
Not the small, low-resolution display an entry price usually buys. 24-bit colour, 300 nit and 8 × 16 divisions — the same panel as the rest of the family.
32 automatic measurements
Voltage, timing and channel-to-channel delay parameters, with five shown on screen at once or all of them together, plus manual, track and auto cursors.
LAN and USB on an entry scope
USB host for a memory stick, USB device for USB-TMC, and a LAN port with VXI-11 — so it can be driven over SCPI from a script like any laboratory instrument.
Pass/fail with a TTL output
Compare the live trace against a mask you define and drive a 3.3 V TTL line on the rear panel from the result. Enough for a simple goods-in or end-of-line check.
Zoom, digital filter and a recorder
Expand any part of the trace against the whole record, filter the input in software, and record continuously into 7 M of recorder memory or out to a USB stick.
Zoom, and thirty-two measurements
The two functions an entry-level scope is most often missing, both standard here.
Zoom
The upper window keeps the whole acquisition with the selected part highlighted; the lower one expands just that part. You never lose your place in the waveform while you look at the detail.
On this model the record is 32 kpts, so zoom is at its best on a repetitive signal you can trigger on reliably — expand the part that interests you rather than capturing a long window and hunting through it afterwards. Expand far enough out of a slow sweep and you will run out of samples; that is the honest limit of a short record, and the reason the comparison above exists.
Where a 50 MHz scope is the right tool
Bandwidth is only worth paying for when the signal needs it. These are the places where this instrument is a sensible buy rather than a compromise.
School and college teaching laboratories
The reason this model still exists. Twelve benches at €277 rather than €359, a screen big enough for two students to read, twelve interface languages and embedded on-screen help. At 50 MHz nothing in a first-year syllabus is out of reach.
Hobby, maker and repair benches
Mains-frequency and audio work, switching supplies, microcontroller I/O, sensor outputs. The measurements are automatic and the interface is conventional, so it is a scope you can hand to someone who has not used one before.
Audio and low-frequency analogue
Where 50 MHz is never the limiting factor. Two channels, 2 mV/div, an FFT with four window functions, and a 6-digit hardware frequency counter cover amplifier, filter and power-rail work comfortably.
Power and mains-frequency electronics
Transformer, rectifier, PFC and mains-timing work all live far below 50 MHz. Use a differential probe for anything floating — the inputs are 400 V and share a ground, so a mains-referenced circuit must never go on them directly.
Matching an existing fleet
If your laboratory already runs SDS1000DL+ or SDS1000CML+ units, another one is identical to drive, takes the same probes and the same case, and is documented by the same manual. Uniformity has a real value when twenty people share the equipment.
Simple goods-in and functional checks
The hardware pass/fail comparator, the TTL output and SCPI over LAN are enough to build a repeatable go/no-go check without paying for an instrument that can do far more.
Three jobs, start to finish
Measurements this instrument does well, worked through the way you would actually do them.
Teaching what a filter actually does
A first-year exercise: measure the −3 dB point of an RC low-pass filter and compare it with the calculated value.
Input on CH1, output on CH2, sweep the source and read Vpp on both channels from the automatic measurement table — no cursors, no arithmetic. Switch on the FFT to see the same result as a spectrum. Two students can read the 7-inch screen at once, which matters more in a teaching laboratory than any specification.
32 automatic measurements with five on screen, two channels, FFT with four window functions. All standard, on the cheapest model in the range.
Chasing ripple on a linear supply
A bench supply hums under load and the output looks clean on a multimeter, which measures the average and tells you nothing about what is riding on it.
AC-couple CH1 on the output at 2 mV/div, trigger on the mains line, and read Vpp and the frequency directly. 100 Hz says rectifier ripple, 50 Hz says something is coupling in, and switching frequencies say it is not this supply at all. The zoom window expands the part of the cycle you care about while the whole waveform stays visible above it.
2 mV/div, AC coupling, AC-line trigger source and the zoom display — and 50 MHz is not remotely the limit on a measurement like this.
A repeatable go/no-go check on the bench
A small production run needs every unit's output waveform checked against a known-good one, by someone who is not an engineer.
Capture a good unit, generate the pass/fail mask from it, and set the tolerance. The instrument then compares every subsequent trace against that envelope and drives the 3.3 V TTL line on the rear panel; the operator watches a lamp rather than a waveform. Over LAN, a script can log the verdicts as well.
Hardware pass/fail with a TTL output, plus LAN with VXI-11 and the full SCPI command set — on an instrument at this price.

It scripts like a laboratory instrument
A LAN port with VXI-11 and a USB device port with USB-TMC are standard, and the instrument answers the SCPI command set, so it drops into an existing test framework rather than needing to be driven by hand. EasyScopeX gives you a remote front panel, screen capture and waveform transfer from a PC, and a LabVIEW driver is published for the family — both are in the downloads below.
The pass/fail output is a 3.3 V TTL line driven by the hardware mask comparator, which is what makes a simple automated go/no-go check possible on an instrument at this price.
About the 9-pin connector in the photograph. Some units carry a DB9 on the rear panel, but neither the data sheet nor the user manual lists RS-232 as a supported interface for this model — both document only USB host, USB device, LAN and the pass/fail output. If you need serial control, ask us first rather than planning around it.

All downloadsQuestions we are asked
How many models are in the SDS1000DL+ series?
In Europe, one: the SDS1052DL+, 50 MHz with two channels. Siglent’s own probe listing also names an SDS1102DL+ and an SDS1202DL+, but neither is in the European price list and we do not stock them. The 70, 100 and 150 MHz members of the same chassis are sold as the SDS1000CML+ series.
Should I spend €13 more on the SDS1102CML+?
Almost certainly, and we would rather say so than sell you the wrong instrument. For €290 against €277 the SDS1102CML+ gives you 100 MHz instead of 50, 1 GSa/s instead of 500 MSa/s and 2 Mpts instead of 32 kpts — sixty-four times the record length for under five per cent more money. Same chassis, same menus, same manual, same case. Buy the SDS1052DL+ when the budget line genuinely will not stretch, or when you are matching an existing fleet of them.
What does the SDS1052DL+ actually sample at?
500 MSa/s in real time, with 32 kpts of record. This is worth stating plainly because the data sheet is shared with the CML+ models and its front page leads with “up to 1 GSa/s” and “up to 2 Mpts” — both of which are the CML+ figures. Read the SDS1052DL+ column of the model table. On repetitive signals the equivalent-time mode reaches 50 GSa/s, but that only works on a signal that repeats.
Does it decode serial buses?
No. There is no I²C, SPI, UART, CAN or LIN decoding on this model and no option that adds it. If you work on embedded buses, the instrument you want is the SDS1202X-E at €339, where all five are standard.
Is 50 MHz and 32 kpts enough for what I do?
It depends entirely on the signal. For audio, mains-frequency work, power supplies, sensor outputs and most microcontroller I/O, comfortably. For fast digital edges, serial buses or anything where you need to capture a long window and then zoom into a short event, the 32 kpts record is the first thing you will run out of — and that is exactly what the €13 step to the SDS1102CML+ fixes.
Can I control it from a script?
Yes. It has USB-TMC and a LAN port with VXI-11, and it answers the standard SCPI command set, so it drops into a test framework like any other instrument. EasyScopeX and a LabVIEW driver are in the downloads below.
There is a 9-pin serial connector on the back — can I use it?
Ask us before you rely on it. Some units carry a DB9 on the rear panel, but neither the data sheet nor the user manual lists RS-232 as a supported interface for this model — both document only USB host, USB device, LAN and the pass/fail output. We would rather tell you that than let you plan a serial installation around a connector we cannot confirm.
How high a voltage can I measure?
The inputs are rated 400 V and the supplied PB470 probes are 150 V / 300 V RMS CAT II. Beyond that you need a differential probe such as the DPB5150. Never put a mains-referenced circuit directly on a scope input — both probe grounds are joined inside the instrument, so the earth lead becomes a short circuit.
Is the series still supported?
Yes. It is in the current Siglent European price list, we hold stock, and firmware is still published — the most recent SDS1000DL+ build is V6.02.01.13. The manual and data sheet are shared with the SDS1000CML+, which is normal for this family and not a sign of neglect; the firmware images are separate.
What warranty and support does it come with?
Three years of manufacturer warranty, handled by us in the Netherlands as the official Siglent distributor for the European Union. We can also supply it with an ISO or DKD/DAkkS calibration certificate — often worth doing on a teaching instrument that has to be demonstrably traceable.
Equipping a teaching laboratory?
Tell us how many benches and what your students will measure, and we will tell you honestly whether the SDS1052DL+ is the right choice or whether €13 a bench is worth spending. We are the official Siglent distributor for the European Union, we hold stock in the Netherlands, and we can supply instruments with ISO or DKD/DAkkS calibration certificates — useful when the equipment has to be demonstrably traceable.
