What is the maximum voltage input supported by these oscilloscopes?

For 50 Ω inputs, both the RTO2024 and RTO64 support a maximum input voltage of 5 V RMS (the RTO64 also lists a maximum peak voltage of 30 V). For 1 MΩ inputs, the RTO2024 supports up to 150 V RMS, while the RTO64 supports up to 300 V RMS CAT I.

Can the hardware bandwidth of the RTO64 be upgraded?

Yes. The RTO64 has a base analog bandwidth of 600 MHz, which is software upgradable up to 6 GHz.

What are the selectable hardware bandwidth limits on the RTO2024?

The RTO2024 has selectable hardware bandwidth limits of 20 MHz, 100 MHz, 200 MHz, 500 MHz, 1 GHz, and 1.5 GHz.

Bandwidth and Acquisition Performance

The models within this series provide different base frequency ranges and signal acquisition rates to match specific application needs:

RTO2024: Features a fixed 2 GHz analog bandwidth (-3 dB) and a calculated rise time (10% to 90%) of 175 ps. It supports a maximum real-time sample rate of 20 Gsample/s when interleaved.
RTO64: Starts with a base analog bandwidth of 600 MHz (-3 dB) and has a calculated rise time of less than 583 ps. The RTO64 bandwidth is software upgradable up to 6 GHz, offering a path for testing higher frequency systems over time.

Vertical Resolution and Signal Fidelity

Vertical resolution determines the quantization level of acquired signals. The two instruments differ in their native hardware resolution, though both support high-definition scaling:

RTO2024: Built around an 8-bit analog-to-digital converter, which can achieve up to 16-bit resolution when operating in High Definition mode. It offers input sensitivities ranging from 1 mV/div to 1 V/div at 50 Ω, and 1 mV/div to 10 V/div at 1 MΩ. The DC gain accuracy is ±1.5% of full scale.
RTO64: Utilizes a native 10-bit analog-to-digital converter, likewise supporting up to 16-bit resolution in HD mode. It provides a wider input sensitivity range, down to 500 µV/div for both 50 Ω (up to 1 V/div) and 1 MΩ (up to 10 V/div). It features a tighter DC gain accuracy of ±1% of full scale for settings of 5 mV/div or higher.

Physical Integration, Display, and Connectivity

The instruments provide distinct physical layouts, screen dimensions, and rear panel connections:

RTO2024: Equipped with a 12.1-inch WXGA capacitive color touchscreen with 1280 × 800 resolution and a SmartGrid user interface. External connectivity includes four USB 3.0 ports, two USB 2.0 ports, a USB 2.0 device port, Gigabit LAN, DVI-D, and a DisplayPort. It has a weight of 9.6 kg and dimensions of 427 mm × 249 mm × 204 mm.
RTO64: Features a larger 15.6-inch TFT capacitive color touchscreen with Full HD (1920 × 1080) resolution. It offers four USB 3.1 Gen 1 ports, two USB 2.0 ports, a USB 3.1 Gen 1 device port, LAN (10/100/1000BASE-T), HDMI, DisplayPort, and an optional GPIB interface. It weighs 13.0 kg with dimensions of 450 mm × 311 mm × 211 mm.
