Keysight U2351A Oscilloscope

While in differential input mode for floating signal sources, the Keysight U2351A Oscilloscope has an extra resistor that is required at each channel to offer a bias return way. The resistor esteem is proportionate to around 100 times the source impedance. If the source impedance is under 100 Ω, the user can interface the negative polarity of the signal straightforwardly to AI_GND, along with the negative input of the Instrumentation Amplifier. The noise couples in differential input mode are less contrasted with the single-ended mode.

The A/D acquisition in the U2351A Oscilloscope requires a trigger source. Once the trigger condition is coordinated, the data acquisition starts. The measured signal is buffered in a data FIFO buffer. The analog inputs can provide input voltages between ±1.25 V to ±10 V (16-bit ADC), aside from U2351A with ±0.05 V to ±10 V (12-bit ADC).

When the U2351A DAQ gadget is switched on, the calibration constant is loaded from the on-board EEPROM to guarantee both the Calibration DACs and PGA circuit are working accurately. Clients are required to set the information arrangement in the Scan List, trigger source, and trigger mode by utilizing SCPI orders.

The polling mode available is the most effortless approach to procure a single A/D data. The A/D converter begins converting one reading at whatever point the committed SCPI command is executed. This mode is appropriate in applications that require the Oscilloscope to process A/D data continuously. In this mode, the timing of the A/D conversion is completely controlled by the product. Notwithstanding, it is difficult to control the A/D conversion rate.
