+# Test Procedure — v0.2.2 Issue #10 Sweep fallback timing
+
+## Purpose
+Verify that sweep fallback no longer depends on an immediate `SYST:ERR?` after the first `SWWV` write.
+
+The new logic should do this sequence:
+
+1. `*CLS`
+2. send first sweep command
+3. wait on `*OPC?`
+4. then read `SYST:ERR?`
+5. only if needed, retry with `SPAC`
+
+## Test files
+- `SDG2042X_V0.2.2.py`
+- `test_v0.2.2_Issue_10_sweep_fallback.py`
+
+## Preconditions
+- SDG reachable via LAN on port `5025`
+- No other program connected to the instrument
+- Output load/test setup safe for a short sweep test
+
+## Command
+Example:
+
+```bash
+python3 test_v0.2.2_Issue_10_sweep_fallback.py --ip 192.168.178.50 --channel C1
+```
+
+Optional custom values:
+
+```bash
+python3 test_v0.2.2_Issue_10_sweep_fallback.py \
+  --ip 192.168.178.50 \
+  --channel C1 \
+  --start 1000 \
+  --stop 5000 \
+  --time 1.0 \
+  --type LIN
+```
+
+## What the script checks
+1. Socket connection and `*IDN?`
+2. Safe baseline setup (`BSWV` to sine)
+3. Direct one-form check for:
+   - `WAV,...`
+   - `SPAC,...`
+4. Production-like bug #10 helper
+5. Stale-error immunity:
+   - inject old error
+   - run helper again
+   - helper must still succeed because it starts with `*CLS`
+
+## Pass criteria
+- `critical tests passed: True`
+- exit code `0`
+- no final `[ERR]` style failures from the script
+
+## Interpretation
+- If only one of the direct forms works, that is acceptable.
+  The important point is that the production-like helper succeeds.
+- If the stale-error test fails, the error-clear / sync sequence is still not robust enough.
+- If both direct forms fail, then bug #10 may be masked by a larger sweep syntax compatibility issue.
+
+## Notes
+This test script intentionally mirrors the current GUI sweep token style (`WAV`, `STAR`) so it checks the real regression path for Issue #10, not a separate protocol cleanup.

+"""Live instrument test for SDG GUI bug #10.
+
+Bug #10
+-------
+Sweep fallback from WAV to SPAC was timing-fragile because the code queried
+SYST:ERR? immediately after the first SWWV write. This script tests the new
+synchronised approach on a real instrument via raw socket SCPI.
+
+What it checks
+--------------
+1. Instrument identity and basic socket comms.
+2. Which direct sweep form the instrument accepts:
+   - WAV,<LIN|LOG>
+   - SPAC,<LIN|LOG>
+3. The production-style fallback logic:
+   *CLS -> SWWV write -> *OPC? -> SYST:ERR? -> optional SPAC fallback
+4. Stale-error immunity:
+   an old queued error should not poison the next sweep apply because the
+   helper clears the error state before the real attempt.
+
+Notes
+-----
+- This mirrors the current GUI sweep token set (WAV / STAR) on purpose,
+  because the target is bug #10 regression testing of the GUI path.
+- The programming guide documents START and SWMD for sweep. This script does
+  not try to resolve that wider compatibility question.
