Siglent oscilloscopes

Use a Siglent scope to inspect rail droop, ringing, rise time, pulse width, and other analog behavior. Captures appear in the Monitor’s Oscilloscope tab. Siglent scopes share the setup, capture, and scripting workflow in SCPI oscilloscopes; this page covers what’s specific to Siglent. For a Siglent spectrum analyzer, see Spectrum analyzer.

Check the model

Embedder supports these exact models:

Family	Models	Channels
SDS800X HD	SDS802X HD, SDS804X HD, SDS812X HD, SDS814X HD, SDS822X HD, SDS824X HD	2 on `2X HD` models, 4 on `4X HD` models
SDS1000X-E	SDS1102X-E, SDS1202X-E, SDS1104X-E, SDS1204X-E	2 on `02X-E` models, 4 on `04X-E` models
SDS2000X Plus	SDS2104X Plus, SDS2204X Plus, SDS2354X Plus	4
SDS1000X HD	SDS1102X HD, SDS1104X HD, SDS1202X HD, SDS1204X HD	2 on `02X HD` models, 4 on `04X HD` models
SDS2000X HD	SDS2204X HD, SDS2354X HD	4

Embedder rejects other models before it changes any settings. Every family supports analog channel and timebase setup, edge triggers, single acquisitions, screenshots, and saved waveforms. The SDS800X HD also supports the advanced triggers below. Support for the SDS1000X-E, SDS2000X Plus, and SDS1000X/2000X HD is tested against simulated scopes. The first time you use one of these models, check a capture against a known signal.

Connect

Put the scope on a network the Embedder host can reach. Read its IP address on the scope under Utility › Menu › I/O › LAN Config. To confirm the host can reach the scope, open http://<scope-ip> in a browser; the scope’s LXI page loads.

In the Monitor, select + to open the Connect tab.
Select the scope under On the bench. LXI discovery finds most scopes automatically.
If the scope isn’t listed, type its address in the search field and select Connect to for that address.
In the scope’s tab, select Set up & connect if it appears. Selecting it approves setup, and Embedder installs what that model needs. Once setup has run, the tab connects to a Ready scope on its own, or shows Connect.

See Connect a bench instrument for device states and controls. LAN is the verified connection. USB VISA resources are accepted, but they need platform drivers or device permissions.

Connect when discovery is blocked

If discovery fails and you work from a hardware script, set the scope’s address in the environment that launches Embedder or VS Code:

export EMBEDDER_SCOPE_HOST=192.168.1.20

With only a host set, scripts connect over VXI-11. If the scope’s VXI-11 server is off, also set EMBEDDER_SCOPE_PORT=5025 to use the raw SCPI socket.

Take a single capture

In the Oscilloscope tab, open the setup panel, set the channels, timebase, and edge trigger, then select Single, Run, or Auto. See Capture in the Monitor for each control. To have Embedder set up the capture, name the channel, coupling, scale, timebase, trigger, and timeout:

Connect to the SDS812X HD at 192.168.1.20. Enable C1 at 1 V/div with DC coupling,
set 1 ms/div, and trigger on C1 rising through 1.5 V. Wait up to 10 seconds,
then show the waveform and the applied settings.

Enable every channel a trigger uses. Embedder refuses a trigger on a channel that’s turned off, because the scope would quietly keep its previous source. To inspect an acquisition already stopped on the scope, ask Embedder to read it without rearming. In a hardware script, scope_connect() with no arguments uses the scope selected in the Monitor:

scope_connect()
scope_set_channel(1, scale=1.0, coupling="DC")
scope_set_timebase(scale=1e-3)
scope_set_trigger(source="C1", level=1.5, edge="rising")
data = scope_capture_waveform(channels=[1], timeout_s=10)
scope_publish_capture(name="C1 rising edge")
scope_disconnect()

Choose a trigger

The Oscilloscope tab sets edge triggers on every model. On models with an external trigger input, its Source list also offers EXT and EXT/5. On the SDS1000X-E, Slope offers rising and falling only. On the SDS800X HD, ask Embedder or use a hardware script for these 13 trigger types:

Trigger	Fires on
Edge	One channel crossing a level: rising, falling, or either.
Slope	An edge that transitions too slowly or too quickly.
Pulse	A pulse whose width passes a test, such as a glitch shorter than 200 ns.
Window	The signal leaving a voltage band, for over- or under-voltage.
Runt	A pulse that clears one threshold but never reaches the other.
Dropout	The signal stopping toggling for longer than a set time.
Interval	The gap between successive like edges leaving a time window.
Nth edge	The nth edge of a burst, after an idle gap.
Pattern	Several channels holding a logic pattern at once.
Qualified	One channel’s edge, gated by another channel’s state or edge.
Delay	One edge arriving too soon or too late after another.
Setup/hold	Data violating setup or hold time against a clock edge.
Video	A composite-video line or field (NTSC, PAL, or HDTV).

On the SDS814X HD, trigger when C1 has a positive pulse above 1.5 V that is
shorter than 200 ns. Wait up to 10 seconds and read back the applied trigger.

SDS800X HD trigger limits:

Sources: analog channels, and LINE for the edge trigger. Edge, pulse, interval, and dropout triggers also accept digital channels D0–D15 when the MSO logic probe is fitted, and a pattern trigger can include them. Slope, window, runt, video, qualified, nth edge, delay, and setup/hold triggers use analog channels only.
No external trigger input. The SDS800X HD has none.
Modifiers: coupling (DC, AC, LF reject, or HF reject), noise rejection, and holdoff by time from 8 ns to 30 s. Not every trigger type accepts every modifier, and Embedder reports one that doesn’t apply.
Serial-bus triggers: the scope supports I²C, SPI, UART, CAN, and LIN triggers, but Embedder sets them only through raw SCPI commands.
Monitor captures: Single and Run in the Oscilloscope tab apply the tab’s edge trigger, which replaces an advanced trigger. To capture on an advanced trigger, ask Embedder or use a hardware script.

The SDS1000X-E, SDS2000X Plus, and SDS1000X/2000X HD support edge triggers only. Embedder rejects other trigger types on these models before it changes the scope. Embedder checks every trigger setting before it writes any of them, so a rejected request leaves the current trigger unchanged. If a capture behaves unexpectedly, ask Embedder to read back the applied trigger.

Measure and save

Capture VDD on C1 and the firmware marker on C2. Trigger when VDD falls below
2.8 V, then report the minimum voltage and the delay from the marker edge.

Save the waveform with its settings. You can also ask for a front-panel screenshot. For instrument functions outside the standard controls, Embedder can send the scope’s SCPI commands from a hardware script with scope_query() and scope_write(). When you configure an unfamiliar setting, ask for the command and its readback.

Troubleshoot

No scope: check the IP address, the network, and the scope’s LAN settings. Select Rescan in the ⋯ menu, or type the address in the Connect tab.
Unsupported: confirm the exact model against the table above.
Trigger rejected: use an edge trigger on models other than the SDS800X HD. On the SDS800X HD, check that the trigger type accepts the source and modifiers you asked for.
Trigger source refused: turn on the channel before you trigger on it.
Trigger timeout: check the enabled source, level, polarity, coupling, and expected event.
Clipped signal: increase volts per division or adjust the offset.
Unexpected old frame: request a new single acquisition and wait for its trigger.
