Description
A scope that barely keeps up will round off steep edges. The Rigol DS9404 oscilloscope reaches 4 GHz at 50 ohm on four analog channels, so fast edges keep their shape. It sits in the MSO-DS9000 family. Lost in HCM lists it for rental and sale, so you can reserve it for a signal-integrity study or own it.
Four gigahertz for fast edges
The DS9404 specifies 4 GHz at 50 ohm. A 1 Mohm input drops that to 500 MHz, so match the input to the probe. Because rise time shrinks as bandwidth grows, a wider scope shows steep edges more faithfully. Sample rate reaches 20 GSa/s in half-channel mode and 10 GSa/s with all channels running.
Rigol DS9404 oscilloscope at a glance
- Bandwidth: 4 GHz at 50 ohm, 500 MHz at 1 Mohm.
- Inputs: four analog channels plus an external trigger.
- Vertical resolution: 8 bit native, 9 to 16 bit in high-resolution mode.
- Display: 10.1-inch touchscreen at 1280 x 800.
- Waveform generator: none integrated.
Depth for long captures
Standard memory is 500 Mpts in half-channel mode and 200 Mpts with all channels. Optional upgrades reach 2 Gpts and 1 Gpts. Deep memory then lets you hold a high sample rate across a long window.
Catching rare glitches
In fast recording mode the scope stores up to 1,000,000 waveforms every second. As a result, an intermittent fault gets many chances to appear on screen.
Projects that suit it
- High-speed digital and signal-integrity studies.
- Embedded-system debugging.
- Laboratory waveform inspection.
- Wideband research work.
Lifecycle and options
Rigol lists the series, yet the catalog entry marks availability as unverified. Lost in HCM therefore confirms stock, options and firmware for each quote. Also check that decode licenses and probes appear on the offer for the Rigol DS9404 oscilloscope.
Rent for a study, or buy for the lab
Rent it for a validation sprint or a design review. Buy it when the same team needs gigahertz capture every week.

DS9404 questions
How deep can the memory go?
Standard depth is 500 Mpts in half-channel mode and 200 Mpts with all channels. Optional memory adds 2 Gpts and 1 Gpts.
How many waveforms per second can it capture?
Up to 1,000,000 in fast recording mode.
Is availability guaranteed?
No. Rigol lists the model, but the entry marks availability as unverified, so Lost in HCM confirms it for each quote.
