Advanced Signal Visualization

Equipped with a 6-inch analog CRT screen, the CRO-20A delivers sharp, stable waveform displays, essential for analyzing fast-moving electronic signals. The vertical sensitivity and dual-channel capacity ensure accurate comparative measurements, enhancing troubleshooting and circuit analysis.

Versatility for Engineering Applications

The wide time base range (0.2 s/div to 0.5 s/div) and variable sweep magnification (x10) accommodate low to high-frequency signal inspection. Designed for portability and easy handling, the instruments solid construction and manageable weight (around 8 kg) suit both field and classroom environments.

Safety and Compliance

Built according to IS 1646:2018 safety standards, the analog oscilloscope guarantees operator protection. Its robust input protection (max voltage 400V) and reliable AC 220V 10% power compatibility ensure consistent and safe operation across varying work conditions.

FAQs of Analog Oscilloscope (Cro):

Q: How do I set up and use the CRO-20A analog oscilloscope for signal measurement?

A: To use the CRO-20A, power it on using an AC 220V supply. Connect your signal source to one of the dual input channels. Adjust the vertical (Volt/div) and time base (Time/div) knobs to scale the waveform as desired. Select the proper input coupling (AC, DC, or GND) based on the signal characteristics, and utilize the trigger controls for stable waveform display.

Q: What is the benefit of having a bandwidth of 20 MHz and a rise time of <17.5 ns?

A: A 20 MHz bandwidth allows the oscilloscope to accurately capture and analyze high-frequency signals up to 20 MHz, while a rise time of less than 17.5 ns ensures precise visualization of fast-transient waveforms. This makes the instrument suitable for testing and troubleshooting electronic circuits where signal fidelity is crucial.

Q: When should I use AC coupling versus DC coupling on this oscilloscope?

A: AC coupling is ideal for observing only the AC component of a signal, effectively blocking any DC offset present. Use DC coupling to view the entire signal, including both DC and AC components. Select the coupling mode that best fits your measurement needs using the AC/DC/GND switch.

Q: Where can the CRO-20A oscilloscopes be utilized effectively?

A: This analog oscilloscope is well-suited for engineering colleges, research laboratories, electronic manufacturing units, and field maintenance services. Its reliable measurement performance and portable design make it practical for diverse testing scenarios.

Q: What is the process for measuring fast voltage transitions using this oscilloscope?

A: To measure fast signals, connect the probe, set the vertical sensitivity to the appropriate range, adjust the time base to a low value (such as 0.2 s/div), and activate sweep magnification (x10) as needed. The CRTs fast response and the instruments high bandwidth provide clear visualization of quick transitions in voltage.

Q: How does IS 1646:2018 compliance benefit users?

A: Compliance with IS 1646:2018 ensures that the oscilloscope meets stringent safety requirements, minimizing electrical hazards during use. This certification offers peace of mind, especially in educational and professional settings where equipment reliability and user safety are paramount.

Q: What are the core components of the CRO-20A and their functions?

A: The core components include the CRT tube (for waveform display), vertical and horizontal amplifiers (for signal processing), trigger circuitry (for waveform stability), and the time base generator (for horizontal sweep control). These parts work together to deliver clear and accurate signal representation.
