Performance and Specifications

When evaluating an oscilloscope, understanding its performance specifications is critical. The Keysight DSOX1204A is engineered to deliver precise and reliable measurements, making it a trusted instrument for various applications. Let's break down some of the key performance aspects:

• Bandwidth: The 200 MHz bandwidth is a primary specification that defines the range of frequencies the oscilloscope can accurately measure. This bandwidth is suitable for most general-purpose applications, including analyzing audio signals, digital circuits, and lower-frequency RF signals. The bandwidth ensures that signals within this range are captured with minimal attenuation.
• Sample Rate: The sample rate of up to 2 GSa/s (Giga samples per second) is another critical factor. A higher sample rate allows the oscilloscope to capture more data points per second, resulting in a more accurate representation of the input signal. This is especially important for capturing fast transient signals and high-frequency waveforms. The DSOX1204A's sample rate ensures that you can capture even brief events with sufficient detail.
• Memory Depth: The memory depth of 1 Mpts (Mega points) allows the oscilloscope to store a large amount of data for each channel. Deeper memory is essential when you need to capture long time windows while maintaining a high sample rate. This is particularly useful for analyzing complex signals that evolve over time or for capturing intermittent glitches. With 1 Mpts of memory, you can zoom in and analyze specific portions of the waveform without losing resolution.
• Vertical Resolution: The DSOX1204A offers 8 bits of vertical resolution, which determines the precision with which the oscilloscope can measure voltage levels. While 8 bits is standard for most oscilloscopes in this class, it provides sufficient resolution for a wide range of applications. This resolution ensures that small voltage changes can be accurately detected and measured.
• Input Impedance: The standard input impedance of 1 MΩ (Megaohm) is suitable for most probing applications. This high impedance ensures that the oscilloscope has minimal impact on the circuit being measured. However, the DSOX1204A also offers a 50 Ω (Ohm) input impedance option, which is useful for impedance matching when measuring high-frequency signals.
• Triggering Capabilities: The DSOX1204A supports a variety of triggering modes, including edge, pulse width, pattern, and video triggering. These advanced triggering options allow you to isolate specific events and capture the data you need. For example, you can trigger on a specific pulse width to capture only those signals that meet certain criteria.
• Accuracy: The DC voltage accuracy is typically around ±3%, which ensures that voltage measurements are reliable and consistent. This accuracy is crucial for making precise measurements and ensuring the integrity of your analysis.

These specifications collectively define the performance envelope of the Keysight DSOX1204A. Understanding these parameters will help you evaluate whether this oscilloscope meets the requirements of your specific applications. Its combination of bandwidth, sample rate, memory depth, and triggering capabilities make it a versatile tool for a wide range of tasks.
