Measurement Category:
The Infiniium V-Series oscilloscopes are not rated for CAT II, III, or IV measurements. They are intended for use only on circuits not directly connected to mains.
The maximum input signal level for V-Series oscilloscopes is ±5 V.
Accuracy Specifications:
- Offset Accuracy: ≤ 3.5 V: ±(2% of channel offset + 1% of full scale + 1 mV); >3.5 V: ±(2% of channel offset + 1% of full scale). Full scale is 8 vertical divisions (60 mV below 7.5 mV/div).
- DC Gain Accuracy: ±2% of full scale at full resolution channel scale (±2.5% for ≤ 5 mV/div). Full scale is 8 vertical divisions (60 mV below 7.5 mV/div).
- Time Scale Accuracy (TSA): Depends on initial accuracy and an aging component that scales linearly from the last time base calibration. Test limits are ±(0.100 + 0.100 x Years Since Calibration) ppm.
Usage Features:
- Calibration: The oscilloscope supports four levels of calibration:
- Environmental Calibration: A quick fine-tune for environmental changes (air flow, temperature, humidity). Takes a few minutes and does not invalidate the Certificate of Calibration.
- User Calibration (Self Calibration): A more rigorous set of calibrations, including optional time scale and interleave correction. Takes about 2-1/4 hours and invalidates the Certificate of Calibration. Requires additional equipment.
- Service Calibration: Performed by Keysight Service Center technicians, includes 50 Ω input resistance calibration. Takes about 2-1/2 hours.
- Factory Calibration: Complete set of calibrations performed during production, with factors stored in flash RAM.
- Self-Tests: Internal procedures to verify proper functioning of the measurement system, keyboard, LEDs, and touch screen.
- Measurement Capabilities: Measures average voltage (V avg), RMS voltage, and frequency.
- Display: Features a 12.1-inch LCD backlit display with capacitive touch screen.
- Connectivity: Includes USB 3.0, SATA, BNC, and LAN connections. Optional GPIB port is available.
- Storage: High-capacity (480 GB or 960 GB) removable solid-state hard disk drive for storing operating system, application software, calibration data, and user files.
