4. Product Introduction
The Keysight (Agilent/HP) E1413C is a C-size, single-slot VXI scanning analog-to-digital converter designed for high-speed, high-channel-count data acquisition. It scans up to 64 channels at rates reaching 100,000 samples per second with 16-bit resolution and 0.01% of reading accuracy.
The module accepts a mix of Signal Conditioning Plug-on (SCP) boards for filtering, gain, strain, temperature, and other sensor interfaces. Dual-ported FIFO memory and a current-value table support both high-speed streaming and real-time monitoring. It remains a standard choice for legacy VXI-based test systems that require reliable multi-channel digitization.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No readings or all zeros | SCP missing/faulty or input open | ✅ High | Verify SCP installation and input connections | Reseat SCPs; check sensor wiring |
| Slow or incomplete scans | Incorrect scan list or trigger setup | ✅ High | Review scan lists and trigger configuration in software | Correct programming; verify trigger source |
| Calibration fails | Internal reference or SCP issue | ✅ High | Run self-calibration command; check error status | Replace module if calibration consistently fails |
| Data errors or noise | Grounding, shielding, or range mismatch | ✅ Medium | Check input range settings and cable shielding | Adjust ranges; improve signal integrity |
| Module not recognized by controller | VXI backplane or address conflict | ❌ Low–Medium | Verify logical address and backplane power | Reseat module; check VXI chassis |
| Over-range or clipped signals | Input exceeds selected range | ✅ High | Monitor actual input voltage vs. programmed range | Select correct range or add attenuator SCP |
If the module fails self-test or produces inconsistent data under known-good conditions, photograph the front panel, SCP configuration, and any error codes, then contact support with the VXI controller details.
6. Frequently Asked Questions (FAQ)
Q: Is the E1413C still in production?
A: No. Keysight (Agilent) has discontinued the E1413C. Units available on the secondary market are typically tested used or new surplus. Availability is limited.
Q: What Signal Conditioning Plug-ons (SCPs) does it support?
A: It accepts up to eight SCPs, including direct input, filters, gain, current source, strain completion, sample-and-hold, and attenuator modules (e.g., E1501A–E1513A series). Confirm compatibility with your sensor types.
Q: Can it measure temperature or strain directly?
A: Yes, when the appropriate SCP is installed (thermocouple, RTD, or strain completion modules). The module performs engineering-unit conversion on board.
Q: What is the maximum sampling rate?
A: Up to 100 kHz aggregate (100,000 channels per second). Actual per-channel rate depends on the number of channels in the scan list.
Q: Does it require a specific VXI controller?
A: It is a register-based C-size module and works with standard VXI command modules and controllers that support SCPI or direct register programming.
Q: Why is a used or surplus unit more affordable than modern DAQ alternatives?
A: This is a legacy VXI product. Pricing reflects secondary-market availability. We verify functionality, including self-calibration and basic scanning performance, and provide limited warranty coverage.
Q: What should I check before installing a replacement?
A: Confirm the VXI chassis has an available C-size slot, note the current logical address and SCP configuration, and back up any existing scan lists or calibration data. Match the exact SCP complement if sensor types are critical.
