This unit
The Keysight E1344A is a B-size, 1-slot VXI register-based multiplexer module engineered for high-voltage thermocouple measurements. It switches 16 channels of high, low, and guard signals to a compatible DMM, enabling multi-point temperature acquisition with automatic cold junction compensation. The module handles DC and AC voltages up to 250 V with channel currents to 50 mA, delivering thermal measurement accuracy within 10 µV differential offset per channel.
Technical Specifications
- Maximum voltage (DC): 250 Vdc (any terminal to any other or chassis)
- Maximum voltage (AC rms): 250 V rms (any terminal to any other or chassis)
- Maximum current per channel (non-inductive): 50 mA
- Maximum power per channel: 1 VA
- Maximum thermal offset (differential Hi-Lo): 10 µV
- Closed channel resistance: 100 Ω ± 10%
- Channel configuration: 16-channel switching (high, low, guard)
- Form factor: B-size, 1-slot VXI module
Key Features
- Thermocouple-compensated relay switching for 16 independent channels
- Automatic cold junction compensation for standard thermocouple types
- Register-based control via SCPI commands
- Includes one analog bus cable for mainframe connectivity
- Closed channel resistance of 100 Ω ± 10% ensures signal integrity
- Thermal offset specification of 10 µV minimizes measurement error in precision applications
Typical Applications Multi-point thermocouple temperature monitoring across industrial, laboratory, and environmental test environments. Channel scanning with automatic type conversion for diverse thermocouple inputs. Integration with VXI-based measurement systems requiring synchronized voltage, current, or resistance measurements alongside temperature data.
Compatibility & Integration Operates with Agilent E1326B or E1411B DMMs. For B-size mainframes (E1300B, E1301B), connect via the analog bus cable supplied with the E1326B DMM. C-size mainframes require the E1403C active adapter. The module ships with one analog bus cable for direct slot-adjacent module connection.

Agilent / Keysight E1344A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight E1344A. Calibration covers all module-specific parameters per manufacturer datasheet, output accuracy and linearity, frequency accuracy, and VXI register and trigger bus compliance. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Agilent / Keysight E1344A faults: relay contact wear, DAC/ADC drift, VXI backplane connector oxidation. Common faults include relay contact wear, DAC or ADC gain drift, and VXI backplane edge connector oxidation. Most modules are repaired at the component level with full post-repair verification in a C-size or D-size mainframe.
