UPO3504E | 500 MHz 4Ch Oscilloscope (Logic Pod Optional)
Overview
The UPO3504E is a 500 MHz mixed signal oscilloscope with 4 analog channels. Digital channels available via optional UT-M15 logic probe pod. It samples at 2.5 GSa/s with 250 Mpts memory depth and captures waveforms at up to 200,000 wfms/s on an 8-inch capacitive touchscreen. All MSO/UPO3000E-series instruments share the same platform — the same sample rate, memory, and measurement engine — with differences only in bandwidth, channel count, and included accessories.
The oscilloscope provides 36 automated measurements with statistics, advanced triggering (edge, pulse width, slope, video, pattern, and area trigger), Bode plot analysis for power supply loop characterization, and web-based remote control via LAN. Serial bus protocol decoding for RS-232, UART, I²C, SPI, CAN, CAN-FD, LIN, and FlexRay is available as optional software licenses.

Key Features
- 500 MHz Bandwidth, 4 Analog Channels — Four-channel capture at up to 500 MHz for mixed-signal debugging and signal analysis.
- 2.5 GSa/s Sample Rate — Captures fast edges and high-frequency content with accurate timing resolution.
- 250 Mpts Memory Depth — Deep memory for capturing long signal records without reducing sample rate.
- 200,000 wfms/s Capture Rate — Fast acquisition reveals infrequent glitches, runts, and timing violations that slower scopes miss.
- 16 Digital Channels (Optional) — Add mixed-signal capability with the UT-M15 logic probe pod (sold separately).
- 36 Automated Measurements — Time, voltage, frequency, and statistical measurements with min/max/average/standard deviation tracking.
- Area Trigger — Draw a region on screen and trigger when a waveform enters or exits it — effective for isolating anomalies in complex signals.
- Bode Plot Analysis — Automated frequency response measurement for characterizing power supply control loops and filter circuits.
- 8-Inch Capacitive Touchscreen — Pinch, zoom, drag, and gesture navigation for efficient waveform interaction.
- Web Remote Control — Access the oscilloscope interface from any browser on the LAN — no software installation required.
- Connectivity — USB, LAN, VGA, EXT trigger, AUX output.
Deep Memory for Complete Signal Capture
With 250 Mpts of memory depth, the oscilloscope maintains its full 2.5 GSa/s sample rate across wide time base settings. This means you can capture an entire communication sequence, a full power-on cycle, or a long servo motor control loop without aliasing or missing events. Zoom into any portion of the captured record to examine details at full resolution.

Optional Mixed-Signal Capability
The UPO3000E platform supports 16 digital channels via the optional UT-M15 logic probe pod. Once connected, digital channels display alongside analog traces with full time correlation — the same mixed-signal debugging capability as the MSO models, added when you need it. Start with analog-only and upgrade to mixed-signal later without replacing the oscilloscope.

Advanced Triggering and Area Trigger
Beyond standard edge triggering, the MSO/UPO3000E supports pulse width, slope, video, pattern, and timeout triggers for isolating specific signal conditions. The area trigger lets you draw a box on screen and trigger when a waveform enters or exits it — particularly effective for catching anomalies in signals where you know what the waveform should look like but not exactly when the fault will occur.

Web-Based Remote Control
Connect the oscilloscope to your LAN and access the full interface from any web browser — no dedicated software installation required. Adjust settings, view waveforms, capture screenshots, and transfer data remotely. This is useful for rack-mounted test setups, shared lab instruments, or situations where the oscilloscope is physically difficult to access.

Professional Applications
- Embedded Systems Development — Debug microcontroller firmware with time-correlated analog and digital views. Decode SPI, I²C, UART, and CAN bus traffic alongside power rails and clock signals.
- Power Electronics — Capture switching waveforms with deep memory, characterize control loop stability with Bode plot analysis, and trigger on specific voltage or timing conditions.
- Multi-Channel Signal Analysis — Four analog channels for simultaneous capture of input, output, reference, and feedback signals in complex circuits.
- Education and Training — The touchscreen interface and automated measurements lower the barrier for students learning oscilloscope operation, while the advanced features support upper-level lab coursework.
- Manufacturing and Quality — Automated measurements with pass/fail limits, web remote control for rack-mounted setups, and data export for test documentation.
Frequently Asked Questions
Can I add digital channels to the UPO3504E later?
Yes. The UT-M15 logic probe pod adds 16 digital channels to any UPO3000E-series oscilloscope. It connects to the logic analyzer port on the rear panel. You also need the UPO3000CS/E-LA16 software license to enable the logic analyzer function.
Are serial bus protocol decodes included?
No. Protocol decoding for RS-232, UART, I²C, SPI, CAN, CAN-FD, LIN, and FlexRay is available as optional software licenses. See the MSO/UPO3000E series page for available decode options.
What is the difference between MSO and UPO models?
MSO models include the 16-channel logic probe pod in the box. UPO models are the same oscilloscope without the logic pod — you can add it later with the UT-M15 and LA16 software license. All other specifications are identical between MSO and UPO models at the same bandwidth and channel count.
Can I upgrade the bandwidth later?
No. The bandwidth is fixed at the factory. Choose the bandwidth you need at purchase — 500 MHz for this model. The 500 MHz and 350 MHz models share the same chassis and feature set.
Part of the MSO/UPO3000E oscilloscope series. All models share the same 2.5 GSa/s sample rate, 250 Mpts memory, and measurement engine. See the series comparison table to find the right combination of bandwidth, channels, and accessories for your application.
