set_channel
Set scale (V/div), offset, coupling (AC/DC/GND), probe ratio, on/off
How to use it
set_channel is exposed by the Rigol MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), and the set_channel tool becomes available to the model automatically. See the full listing for setup details and every tool this server provides.

Auto-configure timebase, vertical scale, and trigger
Query the SCPI error queue
Read cursor positions (in seconds) and all delta/amplitude readouts
Snapshot of all channel configs, timebase, and trigger settings
Download and analyse waveform data (NORM screen buffer: up to 1200 pts on DS1000Z, 1000 on DHO); returns text analysis by default, raw time/voltage arrays with rawdata=true
Identify the instrument — make, model, serial, firmware
Query any single-channel measurement: VMAX, VMIN, VPP, VTOP, VBASE, VAMP, VAVG, VRMS, PVRMS, VUPPER, VMID, VLOWER, VARIANCE, FREQUENCY, PERIOD, PWIDTH, NWIDTH, PDUTY, NDUTY, RTIME, FTIME, OVERSHOOT, PRESHOOT, PSLEWRATE, NSLEWRATE, TVMAX, TVMIN, MAREA, MPAREA, PPULSES, NPULSES, PEDGES, NEDGES
Query delay or phase between two channels. DS1000Z: RDELAY, FDELAY, RPHASE, FPHASE. DHO: RRDELAY/RFDELAY/FRDELAY/FFDELAY, RRPHASE/RFPHASE/FRPHASE/FFPHASE (DS1000Z names auto-map to the homogeneous-edge DHO equivalents)
Start continuous acquisition
Capture display as PNG — returns image inline and saves to disk
Send any SCPI command directly (escape hatch). Disabled by default — set RIGOLENABLESENDRAW=1 to expose it, since arbitrary SCPI can leave the scope in any state.
Set cursor mode (MANUAL/TRACK/OFF) and time positions in seconds
Set time/div and trigger offset
Configure edge trigger: source, slope (POS/NEG/RFAL), level
Arm for one trigger event, then stop
Stop and freeze display
