2420-742 HICKOK Oscilloscope Subassembly

Review HICKOK Oscilloscope Subassembly

The Hickok 2420-742 oscilloscope subassembly is a crucial component in the functioning of a high-performance oscilloscope. This subassembly is meticulously designed and manufactured to deliver precise and accurate measurement results.

At its core, the 2420-742 subassembly is a sophisticated vertical amplifier circuit. It is capable of amplifying and displaying electrical signals in the vertical direction on the oscilloscope screen. The amplifier circuit features a wide bandwidth of up to 200 MHz, ensuring that it can handle a broad range of input frequencies with ease.

The input impedance of the 2420-742 subassembly is 1 M , making it suitable for measuring signals with very low current levels. The subassembly also comes with a built-in 1:2 probe selector, which allows for easy probe selection and signal splitting.

One of the standout features of the 2420-742 subassembly is its high common-mode rejection ratio (CMRR). This ratio is an essential measure of the amplifier's ability to reject unwanted common-mode signals, which can interfere with the measurement of differential signals. The 2420-742 subassembly boasts a CMRR of up to 100 dB, which is an impressive figure and ensures that measurements are not affected by common-mode noise.

The 2420-742 subassembly also comes with a built-in DC offset adjustment feature. This feature allows for the adjustment of the DC offset voltage of the amplifier output, which can be crucial for accurately measuring signals with non-zero DC components. The adjustment range is from -500 mV to 500 mV.

The subassembly is housed in a rugged, compact enclosure, which is designed to withstand the rigors of laboratory use. It comes with a set of standard BNC connectors for input and output signals, as well as a power connector for the oscilloscope.

In summary, the Hickok 2420-742 oscilloscope subassembly is a versatile and high-performance component that delivers accurate and reliable measurement results. Its wide bandwidth, low input impedance, high CMRR, and DC offset adjustment feature make it an essential component for any high-performance oscilloscope setup.

The Hickok 2420-742 oscilloscope subassembly is a component used in oscilloscopes for displaying and analyzing electrical signals. Here are some pros and cons of buying this subassembly:

1. High Precision: The Hickok 2420-742 subassembly is known for its high precision and accuracy in displaying electrical signals. It can handle a wide range of frequencies and voltages, making it a versatile tool for various applications.

2. Durable: The subassembly is built with high-quality components and is designed to withstand heavy usage in a laboratory or industrial setting. It is also resistant to electromagnetic interference, ensuring reliable performance even in noisy environments.

3. Cost-effective: Buying a new oscilloscope can be expensive, but purchasing a subassembly like the Hickok 2420-742 can be a more cost-effective option for those who already have an oscilloscope and only need to replace the display tube or other components.

1. Complexity: Installing and configuring the Hickok 2420-742 subassembly can be a complex process, especially for those who are not familiar with oscilloscope repair or electronics in general. It may require specialized knowledge and tools.

2. Availability: The availability of the Hickok 2420-742 subassembly may be limited, as it is a discontinued model. This could make it more difficult and expensive to obtain, especially for those in need of a replacement in a timely manner.

3. Compatibility: The subassembly may only be compatible with specific oscilloscope models, so it is essential to ensure that it will work with the existing oscilloscope before making a purchase.

In conclusion, the Hickok 2420-742 oscilloscope subassembly offers high precision, durability, and cost-effectiveness, making it an attractive option for those in need of a replacement display tube or other components for their oscilloscope. However, the complexity of installation, limited availability, and compatibility issues may be deterrents for some buyers.

If you have the necessary expertise and are confident in your ability to install and configure the subassembly, and if it is compatible with your oscilloscope, then it could be a worthwhile investment. However, if these factors are a concern, it may be more practical to consider purchasing a new oscilloscope instead. Ultimately, the decision depends on your specific needs, resources, and technical capabilities.
