Rigol DHO914 Oscilloscope, 125 MHz, 4 Analog Channels, 12-Bit, 7-Inch Touchscreen

Description

Teaching labs and service technicians share one need: a compact scope that is easy to learn. The Rigol DHO914 oscilloscope offers four analog channels, 125 MHz of bandwidth and a 7-inch touchscreen in the DHO900 family. Lost in HCM lists it for rental and sale in Vietnam.

The Rigol DHO914 oscilloscope in class and in the field

The listing positions the Rigol DHO914 oscilloscope for embedded debugging, education, serial-bus analysis and field work. A technical school can fill a bench row with units for one term. A maintenance team can also carry one to a machine, because it only needs a signal to probe. Because the screen responds to touch, new users can work through a capture by hand.

What 125 MHz covers

Bandwidth sets the fastest signal a scope shows without heavy rounding. At 125 MHz, the scope suits control signals, sensor outputs and common serial lines. However, faster clocks or sharp edges need more bandwidth, so check your signal first. Then pick the bandwidth that leaves some margin. For comparison, the DHO924 listing gives 250 MHz with the same sampling and memory figures.

Sample rate and memory by channel count

• One channel: up to 1.25 GSa/s with up to 50 Mpts of memory
• Two channels: 625 MSa/s with 25 Mpts
• All channels: 312.5 MSa/s with 10 Mpts

Capture speed also reaches up to 1,000,000 waveforms per second in UltraAcquire mode, and vertical resolution is 12 bit. The 16 digital channels are optional, so ask whether the logic option comes with the unit. These figures also depend on the enabled channels, acquisition mode and installed options.

Rent for a term, or buy for the lab

A course or a field project often ends before a purchase makes sense. Renting then covers the term, so nothing sits idle afterward. If the same scope runs every week, then a purchase quote may suit better. Either way, request a quote from Lost in HCM and name the probes, the logic option and the delivery site. The product photo shows a DHO900 series panel marked DHO924S, so check the label on your unit. For other models, see the oscilloscope listings, the Rigol site, or contact SMK Vietnam.

DHO914 questions

How does it compare with the DHO924?

The listings give 125 MHz here and 250 MHz for the DHO924. They also show the same sample rate, memory and screen figures. Ask Lost in HCM about any other difference.

Does a 125 MHz scope suit serial-bus work?

The listing names serial-bus analysis as a use. Tell Lost in HCM which buses and decoders you need, because the listing does not promise software options.

What happens to sample rate with all four channels on?

It drops to 312.5 MSa/s, and memory falls to 10 Mpts. A single channel still gets the full 1.25 GSa/s.
