Multi-capture API index¶
Use these guides when you need periodic or scheduled captures (for example, hourly RxMER snapshots) along with downstream analysis.
Background Read the capture operation guide first. It explains how capture operations, transactions, and storage hang together.
Workflow at a glance¶
- Plan - Decide whether you need multi-RxMER or multi-channel-estimation captures and confirm storage availability.
- Start - Call the workflow-specific endpoint (for example, multi-RxMER capture) with schedule, modem list, and retention options.
- Monitor - Poll operation status and review logs via the PyPNM system endpoints.
- Download - Use the workflow guide or file manager to grab ZIP archives once captures complete.
- Analyze - Feed the captures into one of the advanced analysis modules listed below.
Multi-capture workflows¶
| Workflow | Purpose |
|---|---|
| Multi-RxMER capture | Periodic downstream OFDM RxMER sampling across multiple carriers. |
| Multi-DS channel estimation | Scheduled OFDM channel estimation captures and reporting. |
| Multi-US OFDMA Pre-Equalization | Multi-sample upstream OFDMA Pre-Equalization capture and analysis under /advance/multi/us. |
Advanced analysis modules¶
| Module | Purpose |
|---|---|
| Multi-RxMER min/avg/max | Roll up RxMER across captures. |
| Multi-ChanEst min/avg/max | Summaries for channel estimation data. |
| Group delay calculator | Compute group delay variations. |
| OFDM performance 1:1 | Compare per-subcarrier capacity vs profile. |
| OFDM echo detection | Detect reflections and echo artifacts. |
| Phase slope LTE detection | Spot LTE-related interference patterns. |
| Signal statistics | Extract RMS/min/max variance from captures. |
