The Keysight E1512A is an 8-channel signal conditioning module (SCP) that provides fixed low-pass filtering and input protection for data acquisition systems. Each channel incorporates a 2-pole low-pass filter with a 3 dB cutoff frequency of 25 Hz, effectively attenuating sensor noise across eight independent measurement channels. The module accepts full-scale voltage inputs ranging from 62 mV to 16 V and delivers corresponding filtered outputs. Built-in input over-voltage protection and open transducer detection on all channels enhance system reliability and fault diagnostics.
## Technical Specifications
• **Channels:** 8
• **Filter Type:** Fixed low-pass, 2-pole
• **Cutoff Frequency:** 25 Hz (3 dB)
• **Input Voltage Range:** 62 mV to 16 V (full-scale)
• **Protection Features:** Input over-voltage protection, open transducer detection
• **Shipping Weight:** 1 lb
## Key Features
• Eight independent channels with identical filter characteristics eliminate cross-channel interference in multi-point measurements.
• Fixed 25 Hz cutoff frequency targets low-bandwidth sensor signals while rejecting higher-frequency noise and electromagnetic interference.
• Open transducer detection automatically identifies sensor connection failures or lead breaks, preventing invalid data collection.
• Input over-voltage protection safeguards measurement circuitry against transient overshoot and sensor faults.
## Typical Applications
• Voltage measurements from instrumentation sensors
• Temperature acquisition using thermocouples, thermistors, or resistance temperature detectors (RTDs)
• Strain measurement systems
Accuracy specifications for temperature measurements include instrument and firmware linearization errors based on ITS-90 transducer curves; add transducer accuracy for total measurement error. Standard terminal block isothermal references introduce ±0.6 °C uncertainty due to temperature gradients. Autoranging operation adds ±0.02% FS to accuracy specifications.
## Compatibility & Integration
The E1512A mounts in VXI card slots. The E1313 VXI card accommodates up to four modules; E1413, E1415, E1419, and E1422 cards accept up to eight modules each. Companion SCP modules extend measurement capability: the E1505A 8-Channel Current Source SCP enables thermistor and RTD measurements, E1506A/E1507A Strain Completion SCPs support strain applications, and E1503A/E1508A/E1509A modules provide enhanced thermocouple accuracy.
